can't get data from row

chucke1992

When I click on a row - I add class info to it.
[code]$("#roletable tbody").click(function(event) {
$(oTable2.fnSettings().aoData).each(function() {
$(this.nTr).removeClass('info');
});
$(event.target.parentNode).addClass('info');
});
[/code]

I want to pass values from selected row(it is always only one row) to modal form when I click on [quote]rolesedit[/quote] button.
I was trying to do like this(I check each row and in order to check data I show alert)
[code]$("#rolesedit").click(function() {
var arr = oTable1.fnGetNodes();
var item = null;
for(var i = 0; i < arr.length; i++) {
if ($(arr[i]).hasClass('info')){
item = oTable1.fnGetData(arr[i]);
alert(item[0]);
}
}
$('#ErolenameInput').val(item[0]);
$('#ERoleID').val(item[1]);
});
[/code]
But item[0] is always undefined.
I was trying something like this too
[code]
$(oTable1.fnSettings().aoData).each(function() {
if ($(this.nTr).hasClass('info'))
alert('has class' + oTable1.fnGetData(this.nTr)[0]);
});[/code]
but it undefined too.

What is the correct way to get data?

Just use fnGetData to get the data for a row :-). I would suggest that the fnSettings object should _never_ be used externally unless you are _very_ familiar with how DataTables works internally. Also the settings object can and will change between releases.

Your second clock block looks more correct. `item[0]` will be undefined if you are using an object data source. Are you?

Yes, I use ajax data source - response from server in json with serialized to json object using GSON.

In which case, just access the object properties as you normally would since fnGetData gives the original data object.

Oh. I see. Thanks.
