在javascript中你可以使用它支持即低版本
<script>
debugger
window.onload = function () {
var childs = document.getElementById('parent').childNodes;
for (var i = 0; i < childs.length; i++) {
childs[i].onclick = function () {
debugger
var pos = indexInParent(this);
alert(pos+1);
}
}
};
function indexInParent(node) {
debugger
var children = node.parentNode.childNodes;
var num = 0;
for (var i = 0; i < children.length; i++) {
if (children[i] == node) return num;
if (children[i].nodeType == 1) num++;
}
return -1;
}
</script>
