How can I get JQGrid to recognize server sent Errors?

Question

I have a jqgrid that\'s functionning very well.

I was wondering is it possible to catch server sent errors ? how Is it done ?

Answer 1

function gridCroak(postdata, _url, grid, viewCallBack, debug) {
$(".loading").css("display", "block");
$.ajax({
    type: 'POST',
    url: _url,
    data: postdata,
    dataType: "xml",
    complete: function(xmldata, stat){
    if(stat == "success") {
        $(".loading").css("display", "none");
        var errorTag = xmldata.responseXML.getElementsByTagName("error_")[0];
        if (errorTag) {
        $("#ErrorDlg").html(errorTag.firstChild.nodeValue);
        $("#ErrorDlg").dialog('open');
        } else {
        var warningTag = xmldata.responseXML.getElementsByTagName("warning_")[0]; 
        if (warningTag) {
            $("#WarningDlg").html(warningTag.firstChild.nodeValue);
            $("#WarningDlg").dialog('open');
        } else {
            if (debug == true) {
            alert(xmldata.responseText);
            }
            jQuery(grid)[0].addXmlData(xmldata.responseXML);
            if(viewCallBack) viewCallBack();
        }
        }
    } else {
        $("#ErrorDlg").html("Servizio Attualmente Non Disponibile !");
        $("#ErrorDlg").dialog('open');
    }
    }
});
}

And In the Grid

datatype : function(postdata) { gridCroak(postdata, 'cgi-bin/dummy.pl?query=stock', 
                                                    "#list", null, false) },

At the end it does use the same approach I think.

Thanks all
