I found this nice little Java script to add table rows on click... I’m not familiar with java and I need to limit the number row added, say only 10 rows can be created. Can someone help me on this? Thanks
<script type="text/JavaScript">
function addRow(r){
var root = r.parentNode;//the root
var allRows = root.getElementsByTagName('tr');//the rows' collection
var cRow = allRows[0].cloneNode(true)//the clone of the 1st row
var cInp = cRow.getElementsByTagName('input');//the inputs' collection of the 1st row

for(var i=0;i<cInp.length;i++){//changes the inputs' names (indexes the names)
cInp[i].setAttribute('name',cInp[i].getAttribute('name')+'_'+(allRows.length+1))
}
root.appendChild(cRow);//appends the cloned row as a new row
}
</script>

Use :


<script type="text/JavaScript">
	function addRow(r){
		var root = r.parentNode;//the root
		var allRows = root.getElementsByTagName('tr');//the rows' collection
		if(allRows.length<10) {
			var cRow = allRows[0].cloneNode(true)//the clone of the 1st row
			var cInp = cRow.getElementsByTagName('input');//the inputs' collection of the 1st row
			
			for(var i=0;i<cInp.length;i++){//changes the inputs' names (indexes the names)
				cInp[i].setAttribute('name',cInp[i].getAttribute('name')+'_'+(allRows.length+1))
			}
			root.appendChild(cRow);//appends the cloned row as a new row
		}
		else {
			alert("You can' add a new row");
		}
	}
</script>
