C＃asp.net的JavaScript调用 [英] C# asp.net calling javascript

问题描述

我有ASP里面的div：内容：

I have a div inside asp:content :

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<div id="slidebar" style="display:none;"  >There are some pending approvals.Please    approve    by the 25th of this month

<a href="#" id="slink" style="margin-left:10px;" onclick="fade('slidebar');">Click here to   close <sup style="font:caption;color:#373636;">X</sup></a>
</div>

<script language="javascript" type="text/javascript">
 function showbanner()
  {
   document.getElementById("slidebar").style.visibility="visible";
  }
</script>
<\asp:content>

和背后的code：

 ClientScript.RegisterClientScriptBlock(Page.GetType(), "displaybanner", "return  showbanner();", true);

我不能把从后面甚至当我直接打电话registerclientscript里面showbanner的声明......它不被调用的code函数showbanner。

I cannot call the function showbanner from the code behind and even when I directly call the statement inside showbanner with registerclientscript ...it doesnt get called .

请帮忙

推荐答案

属性能见度和显示不同样，改变js函数为：

The properties visibility and display are not the same, change the js function to:

function showbanner()
{
    document.getElementById("slidebar").style.display="block";
}

也改变你的code后面

also change your code behind to

ClientScript.RegisterStartupScript(Page.GetType(), "displaybanner", "showbanner();", true);

所以执行脚本的页面加载了，否则将找不到元素之后。

so the script executes after the page has load or else it won't find the element.
