i'm using a simple html file with some rows in it, i need to get the rowindex of the clicked row and send it as parameter to one of my custom javascript methods.
I wont be using any gridview or jquery.
my html would be something like this
<html>
<head>
<body>
<form name=myForm>
<table id=mainTable border=1 width=100%>
<script>
document.write('<tr>')
document.write('<td>')
document.write('row1')
document.write('</td>')
document.write('</tr>')
document.write('<tr>')
document.write('<td>')
document.write('row2')
document.write('</td>')
document.write('</tr>')
document.write('</table>')
document.write('<table>')
document.write('<tr>')
document.write('<td>')
document.write('<input type=button value= move UP onClick=swapRowUp(getRowIndex(this))</input>')>
document.write('<input type=button value=move DOWN onClick=swapRowDown(getRowIndex(this))</input>')>
document.write('</td>')
document.write('</tr>')
document.write('</table>')
</script>
</table>
</form>
</body>
</head>
</html>
<script>
var mainTable = document.getElementById(mainTable);
function getRowIndex(el)
{
while( (el = el.parentNode) && el.nodeName.toLowerCase() !== 'tr' );
if( el )
alert(el.rowIndex);
return el.rowIndex;
}
function swapRowUp(chosenRow) {
if (chosenRow.rowIndex != 0) {
moveRow(chosenRow, chosenRow.rowIndex-1);
}
}
function swapRowDown(chosenRow) {
if (chosenRow.rowIndex != mainTable.rows.length-1) {
moveRow(chosenRow, chosenRow.rowIndex+1);
}
}
function moveRow(targetRow, newIndex) {
if (newIndex > targetRow.rowIndex) {
newIndex++;
}
var mainTable = document.getElementById('mainTable');
var theCopiedRow = mainTable.insertRow(newIndex);
for (var i=0; i<targetRow.cells.length; i++) {
var oldCell = targetRow.cells[i];
var newCell = document.createElement(TD);
newCell.innerHTML = oldCell.innerHTML;
theCopiedRow.appendChild(newCell);
copyChildNodeValues(targetRow.cells[i], newCell);
}
//delete the old row
mainTable.deleteRow(targetRow.rowIndex);
}
function copyChildNodeValues(sourceNode, targetNode) {
for (var i=0; i < sourceNode.childNodes.length; i++) {
try{
targetNode.childNodes[i].value = sourceNode.childNodes[i].value;
}
catch(e){
}
}
}
</script>
now if user clicks row1 i need to get rowindex of it, store it in some variable and send it to my JS methods. so how can i do it ?
this is the complete set of code i used, but i'm unable to swap the rows.
i'm getting the cellIndex as null
