<form method=post action="b.php">
<input type="checkbox" name="test[]" value="1">v1
</form>

<script type="text/javascript">
window.onload=function(){
	var obj = document.getElementsByName("test[]")[0];
	var node = obj.nextSibling;
	alert(node.nodeValue)
}
</script>
	
<form method=post action="b.php"> 
<input type="checkbox" name="test[]" value="1">v1 
</form>
