. aspx 文件中的用 javscript 脚本为控件添加事件
<head >
…
…
<script language="javascript ">
function displayDiv1 ()
{
document .getElementById ( "Div1").style .display ="";
}
</script>
</head>
<body >
<form id="Form1" method="post" runat ="server">
<input type ="button" id="btn2" runat ="server" value ="displayDiv " onclick ="displayDiv1( ) ">
<br >
<div id="Div1" style ="DISPLAY: none; BACKGROUND -COLOR: #009999" runat ="server">
一个 DIV 图层
</div>
<br >
</form>
</body>
aspx.cs 文件中实现上面同样的效果，后台执行 javascript 脚本
A ：测试一个带 alert() 的脚本文件，在 .cs 中执行
//Page_Load () 中添加：
JavascriptRegistEnvent () ； // 在页面显示之前向页面中写入脚本
// 定义 javascriptRegistEvent ()
public Void JavascriptRegistEvent (object sender,EventArgs e)
{
Response.Write ( "run CustomEvent ()...");
Response.Write ( "Regisit dispalyJavascript ....");
// 测试可用
StringBuilder builder=new StringBuilder ( );
builder.Append ( "<script langugage ='javascript '> ");
builder.Append ( "function displayDiv () ");
builder.Append ( "{ ");
builder.Append ( "alert('abc '); ");
builder.Append ( "document .getElementById ('Div1').style.display =''; ");
builder.Append ( "} ");
builder.Append ( "</script> ");
Response.Write ( builder.ToString ());
if( !IsStartupScriptRegistered ("Startup"))
{
this.RegisterStartupScript ( "Startup",builder.ToString ());
this.bnt1.Attributes.Add( "Onclick ", "displayDiv ()");
}
}
// 效果如前台脚本一致吗？似乎有问题！
