js代码

JScript code

function test(){    var myDocument = document;    var htmlElement = myDocument.documentElement    var bodyElement = htmlElement.getElementsByTagName("body")[0];    var items = bodyElement.getElementsByTagName("a");    for ( var i = 0 ; i < items.length; i ++ )    {        var itemAttributes = items[i].getAttribute("id");        if ( itemAttributes.substr(0,3) == "aaa" )        {            var parentTD = items[i].parentNode ;            if ( parentTD != null)            {                parentTD.setAttribute("height","500");                alert(parentTD.getAttribute("onmousedown"));                            parentTD.setAttribute("onmousedown","function anonymous() { ShowDiv(); }");                alert(parentTD.getAttribute("onmousedown"));            }         }    }}    function ShowDiv(){        if ( window.event.button == "2")    {        alert("I'm a Event.....");    }}

HTML code

<body><table border = "1">        <tr>            <td>                 <a id = "aaa" href="#">bbbb</a>                <input type="button" value="test" onClick="test();"/>            </td>        </tr>    </table></body>

js和html代码如上
为什么我在js代码中给td加的onmousedown事件总是不管用呢？

[解决办法]
试一下这样

document.body.onmousedown=function()
{
if(event.srcElement.id.substring(0,3)=="aaa")
{
ShowDiv()
return false
}

}

function ShowDiv()
{
if ( window.event.button == "2")
{
alert("I'm a Event.....");
}
}

[解决办法]
if ( window.event.button == "2")

改为

if ( window.event.button == 2)
[解决办法]
parentTD.setAttribute("onmousedown","function anonymous() { ShowDiv(); }");

==>>>parentTD.attachEvent("onmousedown",ShowDiv);
