GridView1列绑定JS方法,该如何解决

GridView1列绑定JS方法
//这是GRIDVIEW绑定列
<ItemTemplate>
 <a href="return gl_newswindow(" <%# Bind("wldm") %> "," <%# Bind("jydm") %>) "'>设置</a>
 </ItemTemplate>
//JS
<script type="text/javascript">
  function gl_newswindow(wldm,jydm)
{
  window.showModalDialog("../sl_zj_ylkcbz.aspx?wldm=wldm && jydm=jydm,"new","dialogHeight: 370px; dialogWidth: 590px; edge: Raised; center: Yes; help: No; resizable: no; status: no;");
} 
</script>

这样写出错，应该怎么写呢？

请高手帮忙
