js method to achieve color change when mouse passes over table rows_javascript skills

The example in this article describes how to use js to change the color of table rows when the mouse passes over them. Share it with everyone for your reference. The specific implementation method is as follows:

<script type=text/javascript>
<!--
(function(){
 var rows = document.getElementById("listdata");
 var add = function(){
 this.style.backgroundColor="#f3f3f1";
 };
 var del = function(){
 this.style.backgroundColor="#fff";
 };
 for(var m=rows.firstChild;m!=null;m=m.nextSibling){
 m.onmouseover = add;
 m.onmouseout = del;
 }
})();
-->
</script>

I hope this article will be helpful to everyone’s JavaScript programming design.
