提交表单验证功能在IE中不起作用

我正在为一个html表单开发一个简单的javascript验证函数,但是使用IE7遇到了它的问题.我没有收到任何错误消息,表单只是提交而不验证.Firefox和Opera工作正常,所以我真的不确定我在这里做错了什么.我用谷歌搜索,但没有发现任何有用的,或者可能没有谷歌搜索正确的关键字.

*另外,如果有人可以推荐一个好的工具用于在IE中调试javascript.

任何帮助将不胜感激.

问题(奇怪)是由一个名为"parent"的全局变量引起的,你在这里创建:

parent = document.getElementById("parent").value;

JavaScript有自己的变量叫做"父",你要覆盖它,因此混淆了浏览器.你应该将你的声明声明为局部变量,如下所示:

var parent = document.getElementById("parent").value;

这将使它工作.最好总是对那种变量使用"var" - 对你正在使用的所有变量都这样做.

对于JavaScript调试器,您可以使用FireBug在FireFox中进行调试.在Internet Explorer中,Visual Studio很好但价格昂贵.或者您可以通过以下说明免费使用Visual Web Developer:http://www.berniecode.com/blog/2007/03/08/how-to-debug-javascript-with-visual-web-developer-express /
