Scripting All the Elements of a Particular Kind Using DOM


In DOM compliant browsers (IE5 & NS6), you can handle attributes of all similar elements with the getElementByTagName() function. For example, to change the background color of all the cells in a table you can use the following script:
 
<script language=javascript1.2>
function changeColor(){
var tds = document.getElementByTagName("td");
for(i=0;i<tds.length;i++)
     tds.item(i).bgColor = "red";
}
</script>
