Question

当我尝试调用我的小部件时，我收到错误

Uncaught TypeError: Object [object Object] has no method 'koSpreadSheet'

我的插件

(function ($) {

    //Create spreadsheet app
    $.widget('koSpreadSheet', {
        //Default values for options
        options: {

        },

        //Call Constructor
        _create: function () {
            this._CreateTable();
        },

        //Function to Render Table
        _CreateTable: function () {
            $.each(data.info[0], function (key, value) {
                console.log(data.info[0]);
                if ($.isNumeric(value)) {
                    if (jQuery.inArray(key, Equationlhs) === -1) {
                        html += "<td><input type='text' class='numericData' data-bind='value:" + key + "'></td>";
                        head += "<th class='variableHeading header-row' id= '" + key + "' title='Click to bind Equation'>" + key + "</th>";
                        list += "<li class='ui-state-default'>" + key + "</li>";

            var checklist = "<input type='checkbox' id='readonlyCheckbox'><span> Check to make fields ReadOnly</span></br>";
            checklist += "<input type='checkbox' id='viewonlyCheckbox'><span> Check for ViewOnly</span></br>";

            $("body").prepend(checklist);
            $("#div1 thead").append(head);
            $("#div1 tbody").append("<tr></tr>");
            $("#div1 tbody tr").append(html);
        }
    });
})(jQuery);

如何解决此问题

Answer 1

有多个错误：

最重要的是设置命名空间，在当前情况下，我在名称前面使用了自定义。所以你的情况应该是： $.widget('custom.koSpreadSheet');

目前存在一个限制，即必须使用一个名称空间。 [ Learn JQuery]

请注意初始化过程，这样您就不会得到未定义的变量。变量我在调试时遇到问题：
- data
- Equationlhs
- html
- list
- head

我刚用默认值＆amp;初始化了所有内容。使它们全局可用，但你应该对它们的初始化过程进行细粒度控制。

以下是基于您的代码的working example。
