即新对象 - 对象不支持此操作

Question

在IE（全部）中收到错误。每个其他浏览器都处理得很好。

对象不支持此操作

var process = new $.ProcessingModal({ message: "Saving...", wait: 1000 });
process.open();

基本功能设置 $ .ProcessingModal = function（options）{...}

甚至尝试过Object.create。

如果我只能停止支持IE。

$.ProcessingModal = function (options) {
    // default options
    this.defaultOptions = {
        message: 'Processing...',   // message to appear in the process box.    
        wait: 1000,                 // time to wait before showing.
        timeout: null
    };
    // open the process modal
    this.open = function () {
        var o = this;
        var opts = o.defaultOptions;
        opts.timeout = setTimeout(function () {
            $("#process_Modal").modal({
                modalCss: "modH_adj  modW_5 grey_modal",
                onShow: function (dialog) {
                    SetModalFocus(dialog);
                    $("p#process_message > strong").text(opts.message);
                },
                close: false,
                containerId: 'payce_modal_processing'
            });
        }, opts.wait);

        $('body').ajaxStart(function (opts) {
            closeModal(); //close any modal that maybe open.
        });
        $('body').ajaxComplete(function (opts) {
            o.close(opts);
        });
    };
    this.close = function (opts) {
        if (opts == null)
            opts = this.defaultOptions;
        clearTimeout(opts.timeout);
        $.modal.close();
    };
    // set any options.
    $.extend(this.defaultOptions, options);
};
