Code Issues Releases Activity

New: fnUpdate has been updated (oh the irony) to accept either an individual value, an array or an object as the first parameter passed to it. The individual and array options behave exactly as they did before this change - the new option is the object being passed in. This allows fnupdate to be given a data object which is identical to data objects used by the table when using complex objects and mDataProp. How fnUpdate itself actually operates has also changed to be self calling, which makes the multipe column updates for arrays and objects much easier.

/* /*
* Function: fnUpdate * Function: fnUpdate
* Purpose: Update a table cell or row * Purpose: Update a table cell or row - this method will accept either a single value to
* update the cell with, an array of values with one element for each column or
* an object in the same format as the original data source. The function is
* self-referencing in order to make the multi column updates easier.
* Returns: int: 0 okay, 1 error * Returns: int: 0 okay, 1 error
* Inputs: array string 'or' string:mData - data to update the cell/row with * Inputs: object | array string | string:mData - data to update the cell/row with
* mixed:mRow - * mixed:mRow -
* int: - index of aoData to be updated, or * int: - index of aoData to be updated, or
* node(TR): - TR element you want to update * node(TR): - TR element you want to update
* int:iColumn - the column to update - optional (not used of mData is 2D) * int:iColumn - the column to update - optional (not used of mData is an array or object)
* bool:bRedraw - redraw the table or not - default true * bool:bRedraw - redraw the table or not - default true
