从c#调用javascript

Question

我需要使用javascript函数来显示和隐藏页面上的元素,但是在C#方法中调用它.这可能吗？

编辑:我尝试过RegisterStartupScript(见下文),但这并没有像我希望的那样隐藏元素:

HidePopup("CompanyHQSetup", "$('#<%=DivDataProvider.ClientID %>').hide();$('#<%=modalOverlay.ClientID %>').hide();");

private void HidePopup(string Key, string jscript)
    {
        string str = "";
        str += "<script language='javascript'>";
        str += jscript;
        str += "</script>";
        RegisterStartupScript(Key, jscript);
    }

编辑:通过使用隐藏字段布尔来确定是否隐藏或显示元素

是的,请查看RegisterClientScriptBlock.

这是从该链接获取的片段:

  public void Page_Load(Object sender, EventArgs e)
  {
    // Define the name and type of the client script on the page.
    String csName = "ButtonClickScript";
    Type csType = this.GetType();

    // Get a ClientScriptManager reference from the Page class.
    ClientScriptManager cs = Page.ClientScript;

    // Check to see if the client script is already registered.
    if (!cs.IsClientScriptBlockRegistered(csType, csName))
    {
      StringBuilder csText = new StringBuilder();
      csText.Append("<script type=\"text/javascript\"> function DoClick() {");
      csText.Append("Form1.Message.value='Text from client script.'} </");
      csText.Append("script>");
      cs.RegisterClientScriptBlock(csType, csName, csText.ToString());
    }
  }
