防止锚点跟随href

Question

I have an anchor defined as follows -

<a onClick="javascript:isLinked('');" class="..." href="..."><img border="0" alt="" height="8" width="8" src="..."/> <u>Add another</u></a> 

The javascript function -

function isLinked(sId) {
        if(!sId)
        {
            alert(".....");
            return false;
        }
        else
            document.body.style.cursor='wait';                  
    }

Although I do see the alert being triggered on the click of the anchor,the links still follows the target url.
How can i prevent the link from following?

The browser is IE8(if that is relevant)

Answer 1

您需要从onclick处理程序中返回方法返回的值

onClick="return isLinked('');"

Answer 2

The javascript way to disable a link is to add return false; . In your case, the boolean is determined by your function isLinked . So the answer is :

<a onClick="return isLinked('');" class="..." href="..."><img ...

In case that might be of use to you, there's also a css way of disabling links, as documented here .
