Simple JavaScript function to blur an image

Question

I'm using a [jQuery plugin][1] to create a blur an image with the following code:

$(document).ready(function(){
    
var img = new Image();
img.onload = function() {
    Pixastic.process(img, "blurfast", {amount:1});
}
document.body.appendChild(img);
img.src = "image.jpg";

});

How can I rewrite this so than rather than creating the image I can just assign it to < img class="blurthisimage" >?

UPDATE:

New code still not working:

<img src="image.jpg" class="blurthisimage" />

<script type="text/javascript">
$(document).ready(function(){
var img = $(".blurthisimage");
img.onload = function() {
    Pixastic.process(img, "blurfast", {amount:1});
}
});
</script>

Answer 1

Change

img = new Image();

to

img = $(".blurthisimage");

UPDATE Try checking to see if the image is loaded with this

if (img[0].complete == true) {
    Pixastic.process(img[0], "blurfast", {amount:1});
}
else {
    img.load(function () {
        Pixastic.process(img[0], "blurfast", {amount:1});
    });
}

if you wanted to have this work on multiple images use the following:

img.each(function(index, element)
{
    if (img[index].complete == true) {
        Pixastic.process(img[index], "blurfast", {amount:1});
    }
    else {
        img.load(function () {
            Pixastic.process(img[index], "blurfast", {amount:1});
        });
    }
});

If that doesn't work add an alert to inside your onload function to see if it even fires
