如题. 想根据单击事件的返回结果,来出来超链接是否失效.
本来想js直接返回false因该可以. 谁知不行.
<html>
<head>
<script type="text/javascript">
function checkOrderLock()
{
return false;
}
</script>
</head>
<body>
<a href="#" onclick="checkOrderLock();window.location.href='http://www.google.com'";>google</a>
</body>
</html>
<head>
<script type="text/javascript">
function checkOrderLock()
{
return false;
}
</script>
</head>
<body>
<a href="#" onclick="checkOrderLock();window.location.href='http://www.google.com'";>google</a>
</body>
</html>
后 google到 http://www.cnblogs.com/blodfox777/archive/2008/08/27/1277997.html
改成:
<html>
<head>
<script type="text/javascript">
function checkOrderLock()
{
return false;
}
</script>
</head>
<body>
<a href="#" onclick="if(!checkOrderLock()){return false;} window.location.href='http://www.google.com'";>google</a>
</body>
</html>
<head>
<script type="text/javascript">
function checkOrderLock()
{
return false;
}
</script>
</head>
<body>
<a href="#" onclick="if(!checkOrderLock()){return false;} window.location.href='http://www.google.com'";>google</a>
</body>
</html>
就可以了. 这个...

断点小叹号: "当前不会命中断点，源代码与原始代码不同"
不解,google下也无解. 乱点进入 web.config <compilation debug="false"/>
办法:
<compilation debug="true"/>
再调试可行.
