Question

我已经通过某人的帮助获取了这段代码，并希望在点击#print_button后执行该代码。出于某种原因，我不能让它工作，我不知道我哪里出错了？

这是jquery：

     $(document).ready(function () {
         $('#Print_Button').click(function () {


             var html2obj = html2canvas($('#form1'));

             var queue = html2obj.parse();
             var canvas = html2obj.render(queue);
             var img = canvas.toDataURL();

             window.open(img);

         });

     });

以及我的按钮的HTML属性：

id="Print_Button" runat="server" value="Print"

任何人都可以建议我哪里出错吗？

这是正文的完整html：

<form id="form1" runat="server">


    <div class="header">

    <strong class="auto-style11">
        MCN PRINTOUT

    </strong>
        <img alt="Veolia Logo" class="logo" src="logo.png" />

使用输入类型按钮

＆＃13;

 $(document).ready(function () {
         $('#Print_Button').click(function () {
          alert("Clicked");

          //your code here

         });

     });

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<input type="button" id="Print_Button" value="click me"/>

＆＃13;

asp.net - 按钮不会执行功能onclick
