สุ่ม load ภาพด้วย Java Script

Weeraphan K. — Mon, 02 Apr 2007 18:35:30 GMT

In the head, you'll need to paste the following code:

    function newImage()
    {
        document.getElementById("mainImage").setAttribute("src", MyImages[Math.round(Math.random()*3)])
    }
</script>

You'll obviously need to change the file names to what ever files you want to load.

In the <body> tag, you'll also need to add onload="newImage()", so you get something like <body onload="newImage()">

Finally, you need to make sure that you have an image with an ID of "mainImage" on your page somewhere. If you don't, you'll get JavaScript errors.
