js在asp和c#中 有何语法区别？

function datacheck() {
  input1.target="preview";
input1.action="print.asp";
var win = window.open("about:blank","preview","directorys=no,toolbar=no,status=no,menubar=no,scrollbars=no,resizable=no,width=700,height=550,top="+(window.screen.height-550)/2+",left="+(window.screen.width-700)/2+"");
win.focus();
input1.submit();
}
<input type ="submit" value="打印预览(Alt+p)"  accesskey="p"  onClick="datacheck();">

以上代码在asp中可以运行  为何到c#中 运行不了？


c#代码
function datacheck() {
  input1.target="preview";
input1.action="print.aspx";
var win = window.open("about:blank","preview","directorys=no,toolbar=no,status=no,menubar=no,scrollbars=no,resizable=no,width=700,height=550,top="+(window.screen.height-550)/2+",left="+(window.screen.width-700)/2+"");
win.focus();
input1.submit();
}
<form id="form1" method="post" runat="server" >
  <asp:Button ID="btn_submit" runat="server" Text="打印预览(Alt+p)" AccessKey="p" OnClick="datacheck();" />
