急啊！！！关于TD不响应onmousedown简单问题，一经测试成功，马上揭帖

vimson999 2007-10-15 10:24:55

js代码





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.....");

	}

}



<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？

parentTD.setAttribute("onmousedown","function anonymous() { ShowDiv(); }");

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

if ( window.event.button == "2")

改为

if ( window.event.button == 2)

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.....");
}
}
