It is hard to tell what the issue is that you are having. Does mozillado anything when the code is executed? does it display an error? What version of iedid you test it with? And can you also provide the htmlfor the ctrlelement?
很难说你遇到了什么问题。不Mozilla的代码执行时做什么？它是否显示错误？你用什么版本的ie测试的？您还可以提供该元素的htmlctrl吗？
One of the issue with IE and the getElementByIdmethod is that in some versions of the browser it will match on the idattribute of a tag as well as the nameattribute (which does not follow the JavaScript spec). In Mozilla it is only matching using the idattribute.
IE 和该getElementById方法的问题之一是，在某些版本的浏览器中，它将匹配id标签的name属性以及属性（不遵循JavaScript 规范）。在 Mozilla 中，它仅使用id属性进行匹配。
