这个JS代码冲突了，如何修改？
<script type="text/javascript">
function $(id) { return document.getElementById(id); }

function addLoadEvent(func){
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function(){
oldonload();
func();
}
}
}
//以下代码省略
</script>

====================================

<script type="text/javascript">
window.onload = function()
{
var wordinput = document.getElementById("TextBox1");
wordinput.onfocus = function()
{
this.value = "";
}
wordinput.onblur = function()
{
if(this.value == "")
{
this.value = "请输入名称"; }
}
}
</script>
============================
请问如何修改？

[解决办法]
或者把下面的这段放到上面代码的前面
