6 points

In this article, we would like to show you how to get an element by id with jQuery.

Quick solution:

var element = $("#exampleId");

And now we can make numerous operations on this selected element for example:

// change text of div
$("#div-id").text("Changed text.");

// change text of button
$("#button-id").text("Changed text.");

// change value of input
$("input-id").val("Hello world");

 

1. Change text of the button

Runnable example:

// ONLINE-RUNNER:browser;

<!doctype html>
<html>
<head>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.0.0/jquery.min.js"></script>
</head>
<body>
  <button id="example-id">Change text button</button>
  <script>

    $(document).ready(function() {
        var element = $('#example-id');

        element.click(function() {
            element.text('Text button has been changed');
        });
    });

  </script>
</body>
</html>

2. Change text of the div

Runnable example:

// ONLINE-RUNNER:browser;

<!doctype html>
<html>
<head>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.0.0/jquery.min.js"></script>
</head>
<body>
  <div id="example-id">Original text.</div>
  <button>Change Text Button</button>
  <script>

    $(document).ready(function() {
		var element = $("#example-id");

        $("button").click(function() {
            element.text("Changed text.");
        });
    });

  </script>
</body>
</html>
