artdialog4.1.7 弹窗open方法不能调节width

[Java小白进阶之路]

<script src="<%=basePath%>plug-in-js/artDialog4.1.7/artDialog.js?skin=default" type="text/javascript" ></script>
<script src="<%=basePath%>plug-in-js/artDialog4.1.7/plugins/iframeTools.js" type="text/javascript" ></script>

<script type="text/javascript">

function show(url){
art.dialog.open(url,
{title:'',
width:'800px',
height:'300px',
lock:true,
drag:false,
close:function(){
window.location.href='<%=basePath%>manage/department/getDepartmentList.do?totalRootCode=${totalRootCode}';
}
});
}

</script>

在静态页面上测试没问题 在jsp页面上width不生效 但可以调节height
