我正在使用 JS API 3.5。

我的网络应用程序中有一个编辑器小部件。当我在小部件中单击新选择时，它会引发错误“未捕获的类型错误：无法读取未定义的属性“preventDefault”

在 Chrome 和 Firefox 中，即使控制台日志出现此错误，我也可以绘制并继续，但是 IE 11 会因此异常而中断。

确切的错误消息是http://serverapi.arcgisonline.com/jsapi/arcgis/3.5/中第 34 行第 471861 列的未处理异常

0x800a138f - JavaScript 运行时错误：无法获取未定义或空引用的属性“preventDefault”

在 IE 调试文件中，代码看起来像 e 的值未定义。

_onClick:function(e){
        var ok=this.inherited(arguments);
        if(ok)
        {
           if(this.valueNode)           
        {           
          this.valueNode.click();
          e.preventDefault(); //e is undefined
          e.stopPropagation();}
        }
           return ok;
        }

我不知道如何处理此异常，因为我无法在源代码中找到它。

下面包括创建编辑器小部件的代码：

          require(["esri/dijit/editing/Editor",
                "esri/dijit/editing/TemplatePicker",
                 "dojo/domReady!"], lang.hitch(this, function (Editor, TemplatePicker) {

          console.log("click on new Editor => " + ops);
          this.editor = new Editor({
            'settings': ops
          }, editorContainer);
          this.editor.startup();
        }));

我尝试了以下方法，但没有成功： - 包括“dojo/domReady！” 在调用编辑器小部件之前 - 已更改

请帮忙！

这是调用编辑器小部件 onClick 的代码：

   define([
     'dojo/_base/declare',
     'dijit/_WidgetBase',
     'dijit/_TemplatedMixin',
     'dijit/_WidgetsInTemplateMixin',
      'dojo/_base/lang',
      'dojo/dom-construct',
         'dojo/domReady!'], function (declare, _WidgetBase, _TemplatedMixin, _WidgetsInTemplateMixin, lang, domConstruct) {

  return declare([_WidgetBase, _TemplatedMixin, _WidgetsInTemplateMixin], {
      templateString: '<div class="gis_GeoLocation_Dijit"><div style="text-align:center;"><button data-dojo-type="dijit/form/Button" data-dojo-attach-event="onClick:toggleEditing" data-dojo-props="label:\'Start Editing\',baseClass:\'geoLocationButton\'" style="background-color:#ECECEC;" data-dojo-attach-point="toggleBTN"></button></div><div style="margin-top:5px;" data-dojo-attach-point="containerNode"></div></div>',
    widgetsInTemplate: true,
    editor: null,
    isEdit: false,
    templatePicker: null,

    toggleEditing: function () {
      if (!this.isEdit) {
        var ops = lang.clone(this.settings);
        ops.map = this.map;
        ops.layerInfos = this.layerInfos;

        var templatePickerOptions = this.templatePickerOptions;
        templatePickerOptions.featureLayers = this.templatePickerFeatureLayers;

        // create container for Editor
        var editorContainer = domConstruct.create("div", {
