Question

I have jquery script, which should send response to my file. If everything good, I get success, but if wrong, I should get error function, but I get jQuery.handleError is not a function
jQuery.handleError(s, xml, status, e);

How can I change this handleError to other function? Or what can I do?

jQuery.extend({

createUploadIframe: function(id, uri)
{
        //create frame
        var frameId = 'jUploadFrame' + id;
        var iframeHtml = '<iframe id="' + frameId + '" name="' + frameId + '" style="position:absolute; top:-9999px; left:-9999px"';
        if(window.ActiveXObject)
        {
            if(typeof uri== 'boolean'){
                iframeHtml += ' src="' + 'javascript:false' + '"';

            }
            else if(typeof uri== 'string'){
                iframeHtml += ' src="' + uri + '"';

            }   
        }
        iframeHtml += ' />';
        jQuery(iframeHtml).appendTo(document.body);

        return jQuery('#' + frameId).get(0);            
},
createUploadForm: function(id, fileElementId, data)
{
    //create form   
    var formId = 'jUploadForm' + id;
    var fileId = 'jUploadFile' + id;
    var form = jQuery('<form  action="" method="POST" name="' + formId + '" id="' + formId + '" enctype="multipart/form-data"></form>');    
    if(data)
    {
        for(var i in data)
        {
            jQuery('<input type="hidden" name="' + i + '" value="' + data[i] + '" />').appendTo(form);
        }           
    }       
    var oldElement = jQuery('#' + fileElementId);
    var newElement = jQuery(oldElement).clone();
    jQuery(oldElement).attr('id', fileId);

Answer 1

handleError was deprecated from jquery 1.5 and up. I switched from the plugin you are using to this one: http://www.jainaewen.com/files/javascript/jquery/iframe-post-form.html

It’s much simpler and it is pretty easy to modify the plugin to your specific form.

You could try to write your own handleError function as this post suggests: When was handleError removed from jQuery?
