提问一个小问题：在看别人留下的代码中有一段javascript角本：前面有一段后面直接跟了个：void(0)；这是什么意思呀？

没有人吗？

我觉得这段没多大实质作用
比如下面两个应该是一样的作用
<a href="#" onclick=check()>
<a href="void(0)" onclick=check()>

喔
我也觉得
但不敢确定

[hbhbhbhbhb1021]

错了，我刚刚试过了有作用，看其他人的了

[WJY2003]

有什么用呀？？

[startray]

javascript:void(0)相当于取消链接。

会跳转

例：
aa();
void(0)

<script>
function aa()
{..}
</script>

这是什么意思？

The void() function causes the browser to take no redirection action upon clicking. In most modern, javascript-literate browsers you can accomplish the same disarming task by adding a "return false;" at the end of the onClick event code, but you'd still need to provide something in for the href property, so might as well make it javascript:void(0).

you can actually have it invoke a javascript function like so:


<a href="javascript:void(alert('You clicked.'))" >sss</a>

大概意思是防止当前页面重定向到其它页面或重新加载.
