Hello,

The alert() musn’t display, if any checkbox(s) isn’t selected.
How can I do this?

[code=php]
<script language=”javascript”>
function confirmDel() {
var agree=confirm(“Are you sure you want to delete rows?!”);
if (agree) {
return true ; }
else {
return false ;}
}
</script>

<input type=”checkbox” name=”name[]” value=”<?=$id?>”>
<input type=”checkbox” name=”name[]” value=”<?=$id?>”>
<input type=”checkbox” name=”name[]” value=”<?=$id?>”>
<input type=”checkbox” name=”name[]” value=”<?=$id?>”>
<input type=”checkbox” name=”name[]” value=”<?=$id?>”>

<input type=”submit” onclick=”return confirmDel();” />
[/code]

Thanks in advance

@ZABIMay 03.2013 — [CODE]
<script language="javascript">
function confirmDel() {
var inputElems = document.getElementsByTagName('input'), count = 0;
for (var i=0; i<inputElems.length; i++) {
if (inputElems[i].type === 'checkbox' && inputElems[i].checked === true) {
count++;
}
}

if (count<1){alert('select atleast one item');return false;}
var agree=confirm("Are you sure you want to delete rows?!");
if (agree) {
return true ; }
else {
return false ;}
}
</script>

<input type="checkbox" name="name[]" value="<?=$id?>">
<input type="checkbox" name="name[]" value="<?=$id?>">
<input type="checkbox" name="name[]" value="<?=$id?>">
<input type="checkbox" name="name[]" value="<?=$id?>">
<input type="checkbox" name="name[]" value="<?=$id?>">

<input type="submit" onclick="return confirmDel();" />
