An error occur when http response isn't 200

NickZhang

Hi , when i sumbit a create /edit request to the server, as the session timeout or permission denies got 403 response code,

the editor just stuck there and got no response, my question is: is there any way to put a hook to handle such special http response code ?

That depends on how you are sending updates to the server. sample code please.

                        editor = new jQuery.fn.dataTable.Editor( {
                     "ajax": function ( method, url, data, sccess, error ) {
                         jQuery.ajax( {
                                type: 'POST',
                                contentType: 'application/json',
                                url:  'serverURL',
                                data: JSON.stringify(data),
                                dataType: "json",
                                success: function (json) {
                                    sccess( json );
                                },
                                error: function (xhr, error, thrown) {
                                    error( xhr, error, thrown );
                                }
                            } );
                        },

All that http error detail should be in that error function on line 13. You'll need to do some debugging to see if that line is being called correctly.

Now that I'm at work, I can post a sample. I renamed some of the passed-in parameters because I found the variable names in the examples hard to keep track of.

dtEditor = new $.fn.dataTable.Editor( {
[SNIP]
    //this defines how the editor submits data
    ajax: function( method, url, submitData, dtSuccessCallback, dtFailureCallback) {
        $.ajax({
            type: "POST",
            url: myAjaxURL,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            data: JSON.stringify({ ...my data here ...}),
            cache: false,
            processData: true,
            success: function (data, status, xhr) {
                              ... do something with the data that comes back... 
            },
            error: function (xhr, jqAjaxerror, thrown) {
                if ( xhr.status == 412 ) {                      
                    alert("Your change could not be saved because the record has been updated by someone else. Please refresh the screen and enter your change again.");
                } else {
                    alert("Your change could not be saved. Please contact Supper for support with this error information " + xhr.status + "  "+ thrown +". Please note the time and which item you were updating.");
                }
//This tells dataTables editor that the update failed                       
                dtFailureCallback( jqAjaxerror );
            }
        });
    } 
} );
