Desactivate warning

perso80

Hello at everybody,

i would wish desactivate the warning :
[code]
"DataTables warning: Unexpected number of TD elements. Expected 3057 and got 2448. DataTables does not support rowspan / colspan in the table body, and there must be one cell for each row/column combination."
[/code]

It appears if i go to an another page and in the same time, the datatable isn't fully loaded.
How do you can desactivate the warning ?
I didn't find the option to do this.

An solution is to desactivate every click on the document and re-activate when datatable is fully loaded but i would like something more efficient.

[code]
$(document).click(function() {
alert('datatable is'nt fully loaded');
return(false);
});

$('#my-datatable').dataTable({
.....,
.....,
"fnInitComplete": function() {
$(document).unbind('click');
}
[/code]

Thanks in advance.

The warning is there for a reason :-). DataTables is saying that it expected 3057 cells, but found only 2448. So it looks like some cells are missing... This is likely either to be a rowspan / colspan issue as the warning says, or an incomplete table.

Thanks Allan.

Yes, the warning is there for a reason, the document hasn't finished to load, but the user doesn't wait.
I want to remove this.
It's logical because the document isn't fully loaded, but i'm not going to allow the user to click on a link which is

How can i remove a warning caused by the fact to go on an another page (click on a link) ?

It's a daft question - but why is that table being initialised before it has finished loading? It also doesn't explain why DataTables is finding a lot less cells that it is expecting. It does rows * columns, which would suggest that you are loading the columns after the rows!? I presume you are trying to make it quicker for the end user? In which case, perhaps it might be better to use ajax source, or server-side processing?

I initialize datatable in the anonym function $(document).ready(function() { ....

the customization of the datatable is doing. In consequence, i have an error message if the user click on an link before the datatable is fully loaded.

Hi perso80,

I've been investigating this, as it's a bit nasty... What appears to be happening is that the web-browser is telling jQuery to run all functions which are attached using $(document).ready() before the DOM has loaded, due to the click! I've filed a bug with Webkit about this ( https://bugs.webkit.org/show_bug.cgi?id=39683 ), and will also do so with Mozilla. This behaviour seems very odd to me - but all of the browsers do it - so I think I need to come up with some kind of work around. I just don't know what yet...

I'm running into this problem too, and the bug in the browsers seems pretty odd.

I think the simplest work around would be to have some kind of flag like 'sErrMode' to allow disabling of these types of warnings too. I think any and all 'alert' calls should be disable-able for use on a production site - users don't care that I am a terrible programmer and can't make the number of td elements consistent in every row.

It may be an alternative to allow a user defined function to run when an error/warning occurs, to allow the programmer to provide his own error message.

Hi dallin,

sErrMode does indeed allow you to disable the alert()s. Just set it to 'throw' and it will throw a JS error rather than an alert warning. The reason 'throw' is not the default, is because a surprising number of posts in the forum are rooted from missing a JS error... However, an alert you cannot miss! As I roll out more debugging tools for DataTables, I hope to be able to set 'throw' to the default in future.
