Javascript返回false在IE中不起作用

大家好

我的JSP中有以下几行.

I have following lines in my JSP.

<s:submit name="submit" onclick="return validateUser();" action="saveUser" theme="simple" value="Save" />

java脚本方法validateUser()验证用户并返回true或false.验证失败时，不应提交表单.

The java script method validateUser(), validates the user and returns true or false. The form should not be submitted when the validation fails.

这在FF中有效，但在IE8中无效.

This is working in the FF but not in the IE8.

即使验证失败，IE8也会提交表单.

IE8 submits the form even after validation fails.

推荐答案

首先，一个可以执行多项操作的表单是个坏主意，说...

First, a single form that can perform multiple actions is a bad idea, that said...

请不要使用提交按钮，

<button type="button" onclick="javascript:validateUser();">Save user</button> <button type="button" onclick="javascript:deleteUser();">Delete user</button>

现在，您只需要担心表单的默认提交行为(当用户在字段中按Enter时).

Now you only have to worry about default submit behaviour of a form (when user presses enter in a field).
