[CLOSED] Request error

[GavinLou]

When I submit a request, a error was occurred.

Uncaught TypeError: Object [object Array] has no method 'remove'

from: ext.axd?v=38586:8817

The wrong code : this.queue.waitingList.remove(item);

waitingList has no method 'remove'

This error led to my data cannot refresh

The entire code:

onResult : function (options, success, response) {
            if (success === true) {
                if (options.mode === "css") {
                    Ext.util.CSS.createStyleSheet(response.responseText);
                } else {
                    var head = document.getElementsByTagName("head")[0],
                        el = document.createElement("script");

                    el.setAttribute("type", "text/javascript");
                    el.text = response.responseText;

                    head.appendChild(el);
                }

                var i = 0,
                    item = this.queue.getItem(options.url);

                if (item !== null) {
                    item.loading = false;
                }

                if (options.loadCallback) {
                    options.loadCallback.apply(window, [options]);
                }

                if (options.groupCallback) {
                    options.groupCallback.step();
                }

                while (this.queue.waitingList.length > i) {
                    item = this.queue.waitingList[i];

                    if (item.url === options.url) {
                        if (item.loadCallback) {
                            item.loadCallback.apply(window, [item]);
                        }

                        if (item.groupCallback) {
                            item.groupCallback.step();
                        }

                        this.queue.waitingList.remove(item);
                    } else {
                        i++;
                    }
                }
            }
            else {
               Ext.net.DirectEvent.showFailure(response, response.responseText);
            }

            this.queue.dequeue(options);

            this.doLoad();
        },
