Change the mouse pointer using JavaScript


I wanted to use a script to change the mouse pointer on my website using JavaScript. It's better done by CSS but my requirement is of a script that can be distributed to many people to embed in the head section of their websites. Through CSS, this can be manipulated by

html
{
    cursor: *cursorurl*
}

How to do the same in JavaScript?


Solution

  • JavaScript is pretty good at manipulating CSS:

     document.body.style.cursor = *cursor-url*;
     //OR
     var elementToChange = document.getElementsByTagName("body")[0];
     elementToChange.style.cursor = "url('cursor url with protocol'), auto";
    

    or with jQuery:

    $("html").css("cursor: url('cursor url with protocol'), auto");
    

    Firefox will not work unless you specify a default cursor after the imaged one!

    other cursor keywords

    Also remember that IE6 only supports .cur and .ani cursors.

    If cursor doesn't change: In case you are moving the element under the cursor relative to the cursor position (e.g. element dragging) you have to force a redraw on the element:

    // in plain js
    document.getElementById('parentOfElementToBeRedrawn').style.display = 'none';
    document.getElementById('parentOfElementToBeRedrawn').style.display = 'block';
    // in jquery
    $('#parentOfElementToBeRedrawn').hide().show(0);
    

    working sample:

    document.getElementsByTagName("body")[0].style.cursor = "url('http://wiki-devel.sugarlabs.org/images/e/e2/Arrow.cur'), auto";
    div {
      height: 100px;
      width: 1000px;
      background-color: red;
    }
    <html xmlns="http://www.w3.org/1999/xhtml">
    
      <body>
        <div>
        hello with a fancy cursor!
        </div>
      </body>
    
    </html>
