<html>
    <head>
        <script language="javascript">
    function test(event){
        //FF兼容
        var e = event || window.event;
        var el = e.srcElement || e.target;

        if(el.tagName.toLowerCase()=="td")//el可能是table等，但大部分都是td
{
alert(el.id);
}

    }
        </script>
    </head>
    <body>
        <table onclick="test();" border="1">
