2、在html裡用<%=fucntion()%>可以調用 複製代碼 代碼如下:<html xmlns="http://www.w3.org/1999/xhtml%22>
<head runat="server">
<title>Untitled Page</title>
<script language="javascript" type="text/javascript">
function say()
{
var strHello = "<%=Hello()%>";
alert(strHello);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="say();" />
</div>
</form>
</body>
</html>
方法三、 複製代碼 代碼如下:<script language="javascript">
function __doPostBack(eventTarget, eventArgument)
{
var frontForm = document.Form1; //指runat=server的form
frontForm.__EVENTTARGET.value = eventTarget;
frontForm.__EVENTARGUMENT.value = eventArgument;
frontForm.submit();
}
</script>
<input id="Button1" type="button" name="Button1" value="按鈕" onclick="javascript:__doPostBack('Button1','')">
JavaScript中訪問C#變數
方法一：1、通過頁面上隱藏欄位訪問<input id="xx" type="hidden" runat="server">
方法二：1、如後台定義了PUBLIC STRING N;前台js中引用該變數的格式為'<%=n%>'或"+<%=n%>+"
方法三：1、或者你可以在伺服器端變數賦值後在頁面註冊一段指令碼
"<script language='javascript'>var temp=" + tmp + "</script>"
tmp是後台變數，然後js中可以直接存取temp獲得值。
C#中訪問JavaScript的已有變數
方法一：1、前台使用靜態文本控制項隱藏欄位，將js變數值寫入其中；
2、後台用request["id"]來擷取值；
方法二：可以用cookie或session
C#中訪問JavaScript函數
方法一：1、Page.RegisterStartupScript("ggg","<script>SetVisible(1);</script>");
方法二：使用Literal類，然後 複製代碼 代碼如下:private void Button2_Click(object sender, System.EventArgs e)
{
string str;
str="<script language='javascript'>";
str+="selectRange()";
str+="</script>";
//Literal1.Visible=true;
Literal1.Text=str;
}
