Jquery textbox KeyUp event

Jquery textbox KeyUp event

Jquery keypress event. Here we will see how to to get keycode and text when user press the key. we need to attach Jquery keyup event to textbox.


Above code snippet finds input control by Id “Text1” and attach keyup event to it.

var keycode = e.KeyCode ? e.KeyCode : e.which ;

In IE you can get the value of keycode by using “e.KeyCode” but for FireFox it is “e.which”.

So, be careful while using e.KeyCode.

Jquery to get Key Pressed value.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

   <script type="text/javascript" language="javascript">
   $(document).ready( function (){ 
       var key = $(this).val();
       var keycode = e.KeyCode ? e.KeyCode : e.which ;
       var message = key + " " + keycode;
       $("#msg").text( message );

Html code for keyup event

        <input id="Text1" type="text" />    
        <label id="msg"></label>

The same way you can trap the key as soon as it is pressed using keydown event, You can also use keypress() event instead of keyup event to trap the key.

In above example we are finding the key pressed by user inside the input textbox. we are displaying the value of key along with key code inside label control.

You can also trap escape and print screen keys and take appropriate actions.
