Add fnOnParserError function

brunoborges

When there's an error parsing data, we want to be able to decide what to do, instead of displaying an alert.

Here is my suggestion to be applied to default fnServerData

[code]
"error": function (xhr, error, thrown) {
if ( error == "parsererror" ) {
if (typeof oSettings.oInit.fnOnParserError === 'function') {
oSettings.oInit.fnOnParserError(error, thrown);
} else {
alert( "DataTables warning: JSON data from server could not be parsed. "+
"This is caused by a JSON formatting error." );
}
}
}

[/code]

Also, theese lines must be added too:

[code]
DataTable.models.oSettings = {
/**
* Function to be called when there's a parsererror.
* @type functinon
*/
"fnOnParserError": null,

(...)
[/code]

[code]
// Map the initialisation options onto the settings object
(...)
_fnMap( oSettings, oInit, "fnOnParserError" );
[/code]

Is DataTables on github? I could fork from there, and do a pull request
