呼叫ButtonClick（）事件

Question

My event is never being fired, and I can not figure out owhy. 我的活动从未被解雇，我无法弄清楚。 Here is my syntax 这是我的语法

<asp:Button id="btnone" runat="server" visible="false" OnClick="btnone_Click" />
<script type="text/javascript">
  $( document ).ready(function() {
    var button = document.getElementById('btnone').click();
    }
});

And for my C# code behind 对于我后面的C＃代码

protected void btnone_Click(object sender, EventArgs e)
{
    Response.Write("It was clicked through JS");
}

EDIT I have also tried to use this code to capture the ClientID of the button but it's not working 编辑我也曾尝试使用此代码来捕获按钮的ClientID，但它不起作用

$( document ).ready(function () {
  $('<%= btnone.ClientID %>').click();
  }
});

First of all you should set ClientIDMode="Static". 首先，您应该设置ClientIDMode =“ Static”。 Otherwise there will be no element with ID 'btnone'. 否则，将没有ID为“ btnone”的元素。 Also, if you set visible="false" - it does not apply style "display:none;". 另外，如果您设置visible =“ false”-它不会应用样式“ display：none;”。 Instead button won't be on the page. 而是按钮不会在页面上。 You can use this code: 您可以使用以下代码：

.aspx : .aspx：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication2.WebForm1" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script src="//code.jquery.com/jquery-1.12.0.min.js"></script>
    <script type="text/javascript">
        $( document ).ready(function() {
            var button = document.getElementById('btnone').click();
        });

</script>
    <style>
        #btnone
        {
            display:none;
        }
    </style>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <asp:Button id="btnone" runat="server" ClientIDMode="Static" OnClick="btnone_Click" Text="btn"/>
    </div>
    </form>
</body>
</html>

.cs : .cs：

namespace WebApplication2
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void btnone_Click(object sender, EventArgs e)
        {
            Response.Write("It was clicked through JS");
        }
    }
}

First of all, you need to put the property ClientIDMode="Static" in your button, this grants the ID will be the same in runtime, it's what you need to get in Javascript. 首先，您需要在按钮中放入属性ClientIDMode="Static" ，这将授予ID在运行时相同，这是您需要在Javascript中获得的。

In jQuery you need to do something like this: 在jQuery中，您需要执行以下操作：

 $( document ).ready(function() { // Getting the event in a callback $('#btnone').click(function(){ // Work here.. }); // Trigger the event $('#btnone').click(); });

If you want to work in pure JS try something like this: 如果要使用纯JS，请尝试以下操作：

 $( document ).ready(function() { // Here is the callback when the event is triggered function getTheClick(){ // Work here.. } // Assigning the event and it's callback document.getElementById("btnone").addEventListener("click", getTheClick); });

In this case you need to assign a function to an event using the AddEventListener function. 在这种情况下，您需要使用AddEventListener函数将函数分配给事件。
