<a label="Click" onClick="popUp();">

我也有popUp()函数.但是当我点击

<script type="text/javascript">
    function createPopUp(url)
    {
        var w = 600;
        var h = 500;
        var left = (screen.width/2)-(w/2);
        var top = (screen.height/2)-(h/2);
        window.open(url,'name','scrollbars=yes,width='+w+',height='+h+',top='+top+',left='+left);
    }
</script>

但是当我点击该链接它会分解以下错误：

Command not found: popUp() : at Line: 13 :
