如何调用javascript方法 [英] How to call javascript method

推荐答案

试试这个..

try this ..

<div id="divvvv" runat="server">
    <select id="ddlSelect" onchange="changeTest()" name="select1">
           <option value="0" selected="selected">Choose a color</option>
           <option value="1">Red Star</option>
           <option value="2">Yellow Star</option>
           <option value="3">Pink Star</option>
         </select>




in cs file call like this
  divvvv.Attributes.Add("onClick", "javascript:return BindSelect();");

这是你如何从cs页面调用javascipt方法

this is how you can call javascipt method from cs page

StringBuilder strBuilder = new StringBuilder();
strBuilder.Append("<script laungauge='javascript'>");
strBuilder.Append(" MethodName();");
//javascript function name
strBuilder.Append("</script>");

//register script

Page.ClientScript.RegisterStartupScript(GetType(), "InitDiag", strBuilder.ToString());

将MethodName更改为你的javascript方法名称

change the MethodName to yours javascript methods name

尝试如下。

Hi,

try like below.

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), 'yourKey', 'YourJSFunction();', true);

参考 ClientScriptManager.RegisterClientScriptBlock方法（类型，字符串，字符串，布尔值） [ ^ ]



希望它有所帮助。

refer ClientScriptManager.RegisterClientScriptBlock Method (Type, String, String, Boolean)[^]

hope it helps.
