Best method to notify a server error retrieving data.

djpable

I'd like to know the best way to raise a JS alert after a server-side error retrieving data (on re-draw for example).

You can use fnServerData to add your one function to get data from the server (typically using $.ajax()). Here is a an example: http://datatables.net/examples/server_side/post.html , it just needs an 'error' hander added.

I did:
[code]
jQuery.ajax( {
"dataType": 'json',
"type": "GET",
"url": sSource,
"data": aoData,
"success": fnCallback,
"error": function(XMLHttpRequest, textStatus, errorThrown) {
jQuery('html').html(XMLHttpRequest.responseText);
}
});
[/code]

I did this because the web server response is HTML and i want to see the error in the current document. But i see that inspecting the dom, that the responseText is putted on the html node with an empty head and body tag.

How can i fix this ?

You need to change the selector you are giving to jQuery as it is currently writing the the 'html' element in the DOM. Perhaps something like $('div:eq(0)')... although the exact answer will depend on what you want.

I think the code i posted before will be ok.
I'd like to substitute all the document from ... to ... to use all CSS, ...
the web-server give in the case of error (So Tomcat gice his default message, IIS too, and so on).

Thank you anyway, I think i'm off-thread right now.
