- This comes about from thread 29819 which highlights that inserting the
buidler string as a variable into the static file causes issues.
- This will only take effect once 1.10.10 has been released
- The fix is to loop over the data array to find the cell. Slower, but
for an edge case I think this is an approriate fix.
- This fixes DataTables/DataTables #653
- The fix is to replace with more approriate options. The jquery
`$.merge` function in particular is useful and array concat when we
don't need to maintain a refernce.
- This fixes DataTables/DataTables #651
- This was caused by using `_fnGetRowElements` to get the cells. While
it was good for performance with large number or rows to do so, it
isn't needed for a single row and a single line of jQuery is simpliler
and doesn't trigger the set function
- Fixes DataTables/DataTables #638
- The issue was effectively duplicate code - for 1.9- compatiblity when
I introduced 1.10 I had the set function run specifically if a DOM
node was given. But later in the 1.10 series when it became possible
to have the data written to an object rather than an array, that code
would itself call the setter, thus leading to two calls when there is
a DOM node present for the row.
- The first is simply to remove the code that was running the setter for
the DOM specific case.
- This fixes DataTables/DataTables #638 and thread 25846. Thanks to
@Jamaur and @strang91 for following up on this.
- The issue was caused by the check for the `bScrollOversize` option
which looks for the container being the same width as its inner
content area. Obviously that happens to be true if there is no
scrollbar. Adding a check for the clientWidth not being 100 as well
resolves this.
- I've also combined the scrollbar width detection with the other
browser detect functions. The two functions were performing very
similar operations and so easily combined
- The browser detect DOM creation will only run once, rather than for
every table initialisation, optimising multi-table loading
- Fixes DataTables/DataTables #633 - Thanks to @nddery and @epitaphmike
for the input
- If d or objectRead were truthful then the row's data object would be
replaced with an empty object. This was one shortcut in code too many!
- Relates to thread 29530 with thanks to idleog.
- This appears to be caused by setting the prototype chain as an object
directly. For example:
var test = function () {};
test.prototype = {};
$.isPlainObject( new test() );
will return `true` with jQuery 2.1.4 (and `false` for 1.11.3).
If an item is added to the prototype object then it will return
`false`, although for some reason that wasn't the case with
DataTables' API prototype.
More investigation required, but for full compatiblity with exisiting
jQuery releases, the correct thing to do here is to build on the
exisiting prototype, which we can do with `$.extend`.
- This is an interesting one, and I suspect a bit of an edge case in the
browsers - what is happening is that the window is going from having a
scrollbar to not having a scrollbar when the scrolling viewport is
collapsed. This causes the browser to show the scrollbars in the
viewport for an instant, even although they aren't actually required.
If the height of the viewport is 53px and you up it to 80 so there are
no scrollbars and reduce it back to 53 the scrollbars are gone! The
browser must be stopping a race condition once the scrollbars are
shown.
- The fix is to use `max-height` for the scrolling container if the
scroll collapse is set and `height` otherwise. The browser native
methods makes the code _much_ easier to work with, more performant and
easier to understand.
column width for these tables. However, that was in error - it is in
fact required still as the smart width calculations cause the browser to
crash (APPCRASH). There is no indication as to why this is, not is it as
simple as just disabling one or two pieces of code to stop the crash.
This leads me to suspect that it is the number of operations being
performed - particularly to do with the cloning of the elements. If this
is the case, then its just never going to work. Also IE6/7 are such a
small market now (thank goodness) this is just a feature that won't be
available in those browsers.
If anyone is interested in working on fixing it, or paying me to do so,
I'm happy to hear from you :-)
Fix: The auto width calculation table, when scrolling is enabled, being inserted into the scrolling container could cause the viewport to scroll, even when the main table doesn't actually need scrolling. This causes the column width calculations to be incorrect by the scrollbar's width. The fix is to have the calculation table `position:absolute` in the scrolling container and height:1px so it has no effect on the vewport's scrolling.
- These two fixes address DataTables/DataTables #612. Kudos to @Delgan
for reporting these issues and supplying test cases - thanks!
Fix: Table could overscroll if `dt-init data` is used to populate the table
This is a fairly significant change to how DataTables operates for the
scrolling width calculations and primarily is due to a simplification
with the use of `clientWidth` to get the scrolling container width.
Rather than getting the offsetWidth and then removing the scrollbar
width if required the `clientWidth` will give us the value directly.
With the scrollbar width already accounted for the scrolling draw code
can be updated to not need to account for it itself.
Finally, when using the `data` property to add data to the table we need
to recalculate the column widths after the first draw, just like with
Ajax loaded data, otherwise the data added won't be taken into account
and we can get an error in the scrolling.
when body's position is changed (left: 375px) _fnBrowserDetect incorrecly calculates offsets. thus header is a bit misaligned. commit changes test object's position to fixed. in this case it's position will
be relative to the viewport not to the body.
When the table was being destroyed and the remove parameter was passed
in as `true` to remove the table from the DOM there was potential for
bound events to not be unbound from the table elements. This was caused
by the use of the `detach` jQuery method which will not remove events.
Furthermore, rows would not be added to the table before this method (or
`remove()`) was called. As such we need to reorder the code slightly -
attach the rows back into the DOM and then remove them (or detach if the
table is left in the DOM) - otherwise rows which were hidden by paging
would not have their events unbound.
Many thanks for KnowledgeNet ( http://kn-it.com/ ) for their support in
finding and allowing this bug to be addressed!
Being able to get and keep a reference to each row is quite important.
You can't use the DataTables row index for this as it can potentially
change, but we can use IDs, based on a unique value for each row in the
data - `dt-init rowId`.
I've made the decision to not require escaping of data in the ID. This
means that selectors can be ID selectors with a cobontation of other
things (#div.class for example) as that really doesn't make much sense
in this contact - you only have rows that you can select from. Not
requiring escaping makes both the client and library code much easier.
This is documented.
The implemention is to store a reference to each row's data object based
on its id allowing for a trivial lookup. The object has its own index
in the `aoData` array, so there is no `indexOf` required. The only
downside is that the index must be updated when a row is deleted. This
is done with a trivial for loop.
* Issue was that an `error` event was being triggered before the
settings object had been configured. There is no option to trigger an
error event in this case.
* Fixes DataTables/DataTables #572
On line 605, column.sTitle is set to the TH's innerHTML.
On line 1816, column.sTitle is compared with cell.html().
If you have child elements with event handlers on them inside the TH, these are not the same in IE8 (see https://gist.github.com/simonbrent/933e552739477f4be3ab#file-test-html)
As a result, the check on 1816 fails, the contents of the cell is replaced, and the event handlers are removed.
Comparing instead with cell[0].innerHTML fixes this issue.
This is so each repo defines its own integration files, ensuring that
they are both easy to update and that they are up-to-date. I will be
blogging about this change next week.
The main change here is to modify `_selector_run` to loop over the
extension functions (if there are any). This involves passing extra
information to the function (selector type so the correct extension can
be used, settings object and selector modifier to pass on to the
extension method).
The _selector_opts function has also been updated to give the ability to
use unknown properteries through a $.extend, rather than writing a three
property object.
The specificity of pesudo selectors ranks higher than class selectors,
so `tr:hover` will always rank higher than `tr.odd`. Thus giving
`tr:hover, tr.odd:hover` is redundant and this commit removes that
redundancy.
For more about CSS selector specificity see the MDN documentation:
https://developer.mozilla.org/en-US/docs/Web/CSS/Specificity
Fix: Ellipsis elements didn't have padding which could be jarring when shifting between paging that does and doesn't show ellipsis
This fixes DataTables/DataTables #26
Fix: Scrollbar width was being calculated everytime requested on machines with zero width scrollbars
The scrollbar width calculation method has been rewritten to use a
single element with use of `offsetWidth` and `clientWidth` to calculate
the scrollbar width. This works all the way back to IE6.
Previously the CSS shorthand `background` was used for the background of
the header cells, but this makes it a good deal more difficult to set
the background colour if you want to since `transparent` is implicit in
the shorthand used. This method, although a bit longer in CSS is still
fairly simple and a lot more flexible
_fnAjaxDataSrc will in turn call _fnGetObjectDataFn, which
can be specified by the dataSrc method.
This way the dataSrc can set the recordsTotal parameter on
the json data and the changes will be read into the
recordsTotal/recordsFiltered variables.
* This is actually compatible with 1.10.0+ but was never documented (it
wasn't an intended feature, but rather an implementation detail. It
is rather useful though, so is now documented.
* `alert` - Alert the error
* `throw` - Throw an error
* `none` - Do nothing
* A function that is called
New: `dt-event error` event that is triggered when an error occurs (regardless of the value of `$.fn.dataTable.ext.errMode`
Previously the whole row was invalidated as a quick workaround for what
I would would be a complex task, but the solution is actually relatively
simple and small in code size, reusing much of the current invalidation
code. The cache data for the whole row is still removed, but the
important part of minimising the DOM interaction is in place.
Fix: Incorrect returns from sub-methods if a selector does not contain any results (DataTables/DataTables #431)
Update: `dt-api iterator()` has a fourth parameter to indicate that a return value is expected
The basic issue here was the `iterator()`'s automatic check to see if a
new API instance should be returned or not. If there are no results from
a selector the iterator will just use the original API instance to
return, but this isn't correct as we expect an empty result set in this
case. This is partly due to the fact that the top level methods (`row()`
for example) will return 2D arrays, while the child methods will flatten
the results, this is parhaps an error in the API, but too late to fix
now.
To address this, `iterator()` now has a parameter to tell it if a new
instance should be used or not. I debated about a new method
`iteratorNew()`, but I think this is just as clear (which isn't very
clear unfortunatly, but just needs to be made clear in the
documentation, which I've updated for this change).
I've added tests for the selectors with `deferRender` enabled. The test
suite is still in desperate need of update...
This is something that has been in DataTables since the version first
vresion and was contentious at that point so while this is a minor code
change, for me it is quite a big change! I feel that this is the correct
operation now, although it does result in rows being moved around where
they might not be needed to if partial pages could be used.
Improved last page calculation when page size is changed on last page.
e.g. Suppose there are total 12 records and page size is set to 5 records/page. Go to last page, which should be 3, change page size to 10. Page#2 should be selected and it should show 2 records on it.
* This reverts the last commit which documented the old behaviour.
Thinking again about it, if you want to modify the rendered data use
`$(cell).html()`.
* When `dt-init columns.data` / `dt-init columns.render` resolve to a
function, that function is executed. Previously this execution was in
the global scope, but in order to be able to use an instance as a data
source for the row (something I wanted as part of 1.10) we need to
execute the function with the instance's scope. A simple `call()` does
this.
* I could add a check to see if the `rowData` is a plain object or not,
but that would add significant overhead to the processing, and this
particular part of the code needs to be very fast. Additionally, I
think it is unlikely that any one was dependant on this being executed
in global scope, so the change is made.
* This fixes DataTables/DataTables #368.
* 1.10.0 had issues when searching for boolean data as the search
extension methods were checking for empty data, but if found they were
using `''` as the term to filter. It should more accurately just use
the given data.
* Relates, the `_empty()` method was considering `false` to be empty,
but not `true`. Both are now considered to be empty.
* `dt-api state()` - get the last saved state
* `dt-api state.loaded()` - get the state that was loaded when the table
was created
* `dt-api state.save()` - trigger a state save
* `dt-api state.clear()` - clear the saved state
* Fix is to convert from hungarian notation to camelCase in a loop for
the array
New: State staving object structure is now full documentated
* The structure has been altered to be camelCase notation like the rest
of the 1.10 API. State loaded from older versions of DataTables will
be silently ignored
* The native `forEach` is suprisingly slow. I had assumed that it would
be faster that a for loop, but it appears that due to the function
execution it is actually much slower. A simple for loop is much better
for performance and we loose nothing since hte API instance is array
like.
* This fixes DataTables/DataTables #364
* It appears that if you have a reference to a DOM node, but that DOM
node is overwritten by use of innerHTML, the reference is destroyed
and you cannot use the referenced DOM node any more.
* This became apparent from using Editor's inline editing mode, where in
IE the inline edit would work only once. No other browser has this
issue but it is in IE7-DC1.
* The workaround is to remove the child nodes first. not ideal at all,
but it does work.
* Searching the internet I didn't find much about this so I've opened an
issue on the IE connect site:
https://connect.microsoft.com/IE/content/content.aspx?ContentID=29582
* DataTables uses custom jQuery events which propagate up through the
DOM, with the custom event being triggered on the table node. Ideally
I'd like to change the event handling to use $().triggerHandler() to
avoid this issue, but as discussed in issue #245 that would mean that
delegated events wouldn't work. Perhaps there should be two forms of
events triggered by DataTables, those which do bubble and those which
do not. `init` is the only one which would _have_ to bubble.
* The workaround for the moment is to check that the settings object in
context of the executed settings handler is the same as the one that
was used in the addition of the event handler.
* This fixes DataTables/DataTables #361
* In particular this fixes the FixedColumns + ColReorder example which
was showing the problem by expanding the columns to the full container
width for each column. See thread 20848 for information.
