问题描述
我正在使用带有一点动画的菜单控件.
我正在使用另外两个munu's.我不想使用所有菜单.
我只想根据自己的情况一次只显示一个菜单控件.
我收到错误消息所需对象:在"DIV"中标识为空
我没有在代码中使用任何"DIV".为什么在"DIV"中显示为空
为什么会出现错误...?
请参阅下面的完整代码...

I did''t use any "DIV" in my code. why it shows null identied in the "DIV"
why the error will come...?

我得到的错误对我没有意义?
必需的对象
如果(this.element.tagName ===``DIV''){
在下面的系统生成的JavaScript摘录中突出显示了.
(但是我正在使用VB.Net-Framework 4.0-因此，DIV应该是div-但我没有div，所以看不到在哪里引入一个?)
if(！window.Sys){window.Sys = {}; }
如果(！Sys.WebForms){Sys.WebForms = {}; }
Sys.WebForms.Menu = function(options){
this.items = [];
this.depth = options.depth || 1;
this.parentMenuItem = options.parentMenuItem;
this.element = Sys.WebForms.Menu._domHelper.getElement(options.element);
如果(this.element.tagName ===``DIV''){
var containerElement = this.element;
this.element = Sys.WebForms.Menu._domHelper.firstChild(containerElement);
this.element.tabIndex = options.tabIndex || 0;
options.element = containerElement;
options.menu = this;
this.container = new Sys.WebForms._MenuContainer(options);
Sys.WebForms.Menu._domHelper.setFloat(this.element，this.container.rightToLeft?"right":"left");
}
其他{
this.container = options.container;
this.keyMap = options.keyMap;
}
The error I get makes NO sense to me?
Object required
if (this.element.tagName === ''DIV'') {
is highlighted in the extract from the system generated JavaScript below.
(But I''m using VB.Net - Framework 4.0 - so, DIV should be div - but I have no div and can''t see where to introduce one?)
if (!window.Sys) { window.Sys = {}; }
if (!Sys.WebForms) { Sys.WebForms = {}; }
Sys.WebForms.Menu = function(options) {
this.items = [];
this.depth = options.depth || 1;
this.parentMenuItem = options.parentMenuItem;
this.element = Sys.WebForms.Menu._domHelper.getElement(options.element);
if (this.element.tagName === ''DIV'') {
var containerElement = this.element;
this.element = Sys.WebForms.Menu._domHelper.firstChild(containerElement);
this.element.tabIndex = options.tabIndex || 0;
options.element = containerElement;
options.menu = this;
this.container = new Sys.WebForms._MenuContainer(options);
Sys.WebForms.Menu._domHelper.setFloat(this.element, this.container.rightToLeft ? "right" : "left");
}
else {
this.container = options.container;
this.keyMap = options.keyMap;
}
