I am hiding a paragraph on button_click and showing again on the click of the same button using jquery.
But when I click on the button nothing happens not even error is displayed. I have checked using inspect element in the browser. There is no error. Here is my code.

C#

<body>
<%--<script type="text/javascript" language="javascript" src="Script/Hideshow.js"></script>--%>
  <%--<script src="Script/jquery-2.1.1.js" type="text/javascript"></script>--%>
   
    <script src="Script/jquery-2.1.3.min.js" type="text/javascript"></script>
  <script type="text/javascript">
     
      $('#hide_show').click(function () {
          alert("hello");
          var value = $('#hide_show').attr('value');
          $('#message').toggle('fast');
          if (value == 'Hide') {
              $('#hide_show').attr('value', 'Show');

          }
          else if (value == 'Show') {
              $('#hide_show').attr('value', 'Hide');
          }
      });
  </script>
    <form id="form1" runat="server">
    <div>
        <input id="hide_show" type="button" value="Hide"  />
    <p id="message">This is paragraph </p>
    </div>
    </form>
</body>

Please tell me what is wrong in this code.

The only change is that I wrapped the binding of click in document-ready...

You try to fetch hide_show before it's created.

To be sure that you only execute the JavaScript code when all DOM objects are created, there are two options:

You can put the script at the end of your body tag.

You can execute the code in a document.ready event handler, like this:

JavaScript

$(function() {
    // the code here is executed when the DOM is ready
    $('#hide_show').click(function () {
        alert("hello");
        var value = $('#hide_show').attr('value');
        $('#message').toggle('fast');
        if (value == 'Hide') {
            $('#hide_show').attr('value', 'Show');
        }
        else if (value == 'Show') {
            $('#hide_show').attr('value', 'Hide');
        }
    });
});

You have placed the script code before the HTML elements. hide_show is not there yet when you declare #hide_show.
You should either put the script code inside $( document ).ready() or after all the HTML elements.

<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
      $('#hide_show').click(function () {
          alert("hello");
          var value = $('#hide_show').attr('value');
          $('#message').toggle('fast');
          if (value == 'Hide') {
              $('#hide_show').attr('value', 'Show');

          }
          else if (value == 'Show') {
              $('#hide_show').attr('value', 'Hide');
          }
      });
});
</script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <input id="hide_show" type="button" value="Hide"  />
    <p id="message">This is paragraph </p>
    </div>
    </form>
</body>
</html>

$( document ).ready()[^]
