从后面的代码中调用javascript方法

Question

此代码在另一页中有效，但在新页面中不起作用

JS函数被称为：

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
  <script type="text/javascript">
    function myfun() {
      alert("test");
    }
  </script>
</asp:Content>

HTML代码：

<asp:TemplateField>
  <ItemTemplate>
    <asp:ImageButton CssClass="Link" ID="IMGDetail" 
         ClientIDMode="Static" runat="server" 
         ImageUrl="~/Img/Detail.png" Height="19px" 
         Width="19px" OnClick="IMGDetail_Click" ToolTip="Detail" />
  </ItemTemplate>
</asp:TemplateField>

后面的代码：

protected void IMGDetail_Click(object sender, ImageClickEventArgs e) {
  LinkButton lbtn = (LinkButton) sender;
  GridViewRow gvr = (GridViewRow) lbtn.NamingContainer;
  Label LabelTicketId = (gvr.FindControl("LBTicketId") as Label);
  Session["TicketId"] = LabelTicketId.Text;
  ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text", "myfun()", true);
}

我认为您需要在aspx页面中添加以下标记。

<asp:ScriptManager ID="ScriptManager" runat="server" />

在Codebehind

ScriptManager.RegisterStartupScript(this, typeof(string), "myfun", "myfun()", true);
