如何禁用页面上的a链接

方法一：

<a href="http://www.baidu.com" onclick="test1()" ondblclick="test2()" name="ah">aaaaaaaaaaaaaa</a>
<a href="http://www.baidu.com" onclick="test1()" ondblclick="test2()" name="ah">aaaaaaaaaaaaaa</a>
<a href="http://www.baidu.com" onclick="test1()" ondblclick="test2()" name="ah">aaaaaaaaaaaaaa</a>
<a href="http://www.baidu.com" onclick="test1()" ondblclick="test2()" name="ah">aaaaaaaaaaaaaa</a>

<script>
    var ahs=document.getElementsByName("ah");
    for(var i=0;i<ahs.length;i++){
        ahs[i].disabled=true;
        ahs[i].ondblclick=null;
        //ahs[i].href="#";    
       ahs[i].href="javascript:void(0)";
    }
</script>

方法二(csdn上一位网友给出的):

<div id="cs">
<a href="http://www.g.cn/" target="_blank">google</a>
<a href="http://www.baidu.com/" target="_blank">baidu</a>
<a href="http://community.csdn.net/" target="_blank">csdn</a>
</div>
<script type="text/javascript">
!function (id) {
    var a = document.getElementById(id).getElementsByTagName('a'), i = 0, l = a.length;
    for (; i < l ; i ++) {
        a[i].onclick = function (e) {
            e = window.event || e;
            if (e.preventDefault)
                e.preventDefault();
            else
                e.returnValue = false;
        };
    }
    a = null;
}('cs');
</script>

ahs[i].onclick=function(){return false;};
