form.action赋值 - 对象不支持此属性或方法

Question

JSP

<form:form id="myForm" action="myAction.html" name="sws" commandName="myModel" method="POST">
    .
    .
    </form:form>

的Javascript

var currentForm=document.getElementById("myForm");
currentForm.target = '_self';
currentForm.action = 'myAction2.html';
currentForm.submit();

我在IE 7中遇到错误object doesn't support this property or method，在行 - ＆gt; currentForm.action =＆＃39; myAction2.html＆＃39;;

Answer 1

用以下jquery代码替换Javascript代码解决了这个问题。我仍然想知道，如何以及为什么。

$("#myForm").attr({'target': '_self' , 'action': '/MyApp/forms/MyAction2.html'}).submit();
