你好，

如果您正在使用JavaScript，并且想要访问主页的内容页面，然后只需将javascript代码放在母版页的head标签部分。通过这种方式，当您添加任何与该母版页链接的内容页面时，您将看到在该页面上工作的java脚本。

Hello,
If you are using JavaScript, and Want to access is on Content Page of Masterpage, then simply put the javascript code in the , head tag section of masterpage. By this , when you will, add any content page, linked with that master page, you will see java script working on that contantpage.

这是我在母版页上包含div的方式（外部ContentPlaceHolder）：

This is how I included div on Master page(outside ContentPlaceHolder):

<div id="DivTest" style="width: 200px;">
</div>

这是我在子页面上写的代码（在ContentPlaceHolder中）：

This is the code I wrote on child page(inside ContentPlaceHolder):

<script language="javascript" type="text/javascript">
        //        function getwidth() {
        var content_div = document.getElementById('DivTest');
        var content_width = content_div.clientWidth;
        alert('content_width=' + content_width + 'px');
        // }
</script>

有效。

It worked.
