if(document.getElementById("隐藏域").value=="")
{document.getElementById("隐藏域").value =document.getElementById("a1").href;
document.getElementById("a1").href="";}else{
document.getElementById("a2").href=document.getElementById("隐藏域").value;
document.getElementById("隐藏域").value =document.getElementById("a1").href;
document.getElementById("a1").href="";
}
a2事件
document.getElementById("a1").href=document.getElementById("隐藏域").value ;
document.getElementById("隐藏域").value =document.getElementById("a2").href;
document.getElementById("a2").href="";

<a>a1</a><a>a2</a>
<input id="隐藏" value>

------解决方案--------------------
探讨


$("#a1").client()

说下思路吧。。获取A1 和A2的href值。 a1触发事件的时候a1的href值清空。并保持到临时变量中。可以是隐藏域。然后当a2触发事件的时候a2的href值清空。并且把临时值传给a1、、
a1的事件
JScript code
if(document.getElementById("隐藏域").value=="")
{document.getEl……


------解决方案--------------------
写了一个比较笨的方法。
JScript code

<script type="text/javascript">
    var a3="true";
    var a4="true";
    $(document).ready(function(){    
        $("#a3").bind({
            "click":function(){
                if(a3=="true"){    
                    window.open("www.baidu.com","_blank");
                    a3="false";
                    a4="true";
                }
            },
            "mouseover":function(){
                if(a3=="true"){
                    $("#a3").css("text-decoration","underline");
                    $("#a3").css("cursor","hand");
                }        
            },
            "mouseout":function(){
                if(a3=="true"){
                    $("#a3").css("text-decoration","");
                    $("#a3").css("cursor","");
                }        
            },
            "mouseup":function(){
                if(a3=="true"){
                    $("#a3").css("text-decoration","");
                    $("#a3").css("cursor","");
                }        
            }
        });
        $("#a4").bind({
            "click":function(){
                if(a4=="true"){
                    window.open("www.google.com","_blank");
                    a4="false";
                    a3="true";
                }
            },
            "mouseover":function(){
                if(a4=="true"){
                    $("#a4").css("text-decoration","underline");
                    $("#a4").css("cursor","hand");
                }        
            },
            "mouseout":function(){
                if(a4=="true"){
