css中可否定义onclick事件?
如题


------解决方案--------------------
ie下可以,俺曾经试验过,不过这么做确实有点儿bt,哈

还是用js实现更好一些!

JS实现,L@_@K
JScript code

    <script type="text/javascript">
    <!--
function setElementsByClassName(className)
{
    var allEles = document.body.childNodes;

    for (var i=0; i<allEles.length; i++)
    {
        if (allEles[i].className 
            && allEles[i].className == className)
        {
            allEles[i].onclick = function()
            {
                alert(this.tagName + " " + this.type);
            };
        }
    }
}
setElementsByClassName("enableClick");
    //-->
    </script>
</body>
</html>

css+expression实现,不推荐!
注:IE6sp1下可用,其他浏览器未测试!
