每当dijit select中的选择发生变化时，我都会显示一个dijit对话框。问题是我得到一个“未捕获范围错误：在dijit select中进行另一个选择之前，如果没有手动关闭对话框（单击对话框右上角的X），则会出现“超出最大调用堆栈”。我尝试在使用.show（）方法之前使用.hide（）方法隐藏对话框--但我仍然得到相同的错误。有什么方法可以防止此错误吗？
//选择模板：

<div>
    <br /><select name="selectMAS" style="width: 150px; height:20px;"
                                    data-dojo-type="dijit/form/Select" data-dojo-attach-point="selectMAS" 
                    data-dojo-attach-event="onChange:MASChange"></select>
</div>

//从select打开对话框的代码：

MASChange: function (evt) {
//show the dialog when the selection changes (content of the dialog changes with the selection)
NSRF.NSRFDialog.show();//NSRF created in postcreate of class

}

//对话框模板：

<div>
    <div data-dojo-type="dijit/Dialog" title="New Service Request Form" data-dojo-attach-point="NSRFDialog" class="nonModal">
        TEST
</div>
</div>

//对话框代码：

define([
  "dojo/_base/declare",
  "dijit/_WidgetBase",
  "dijit/_TemplatedMixin",
  "dijit/_WidgetsInTemplateMixin",
   "dojo/dom", "dojo/ready", "dojo/dom-style", "dojo/on",
  "dojo/text!Templates/test.htm"
], function (declare, _WidgetBase, _TemplatedMixin, _WidgetsInTemplateMixin,
    dom, ready, style, on,
    NSRFTpl) {
    return declare([_WidgetBase, _TemplatedMixin, _WidgetsInTemplateMixin], {
        templateString: NSRFTpl,

        postCreate: function () {

        },
        destroy: function () {

            this.inherited(arguments);
        },
       showForm: function () {
            //fill in some info in the form later
        },

    });
});

谢谢
查看调用堆栈，发现错误：Select.js

try {
    this.focusNode.focus()
} catch (a) {}
}, focusChild: function(a) {
        a && this.set("value", a.option)
    }, _getFirst: function() {
        var a = this._getChildren();
        return a.length ? a[0] : null
    }, _getLast: function() {
        var a =

型
init.js

try {
    a.focus()
} catch (c) {}
}
}));
b(function() {
    var a = v.registerWin(r.get(document));
    c("ie") && d(window, "unload", function() {
        a && (a.remove(), a = null)
    })
});
s.focus = function(a) {
    v.focus(a)
};
for (var w in v) /^_/.test(w) || (s.focus[w] = "function" == typeof v[w] ? g.hitch(v, w) : v[w]);
v.watch(function(a, c, b) {
    s.focus[a] = b
