jQuery Question

curving text using button jquery

i would like to know how i can make more designs using http://circletype.labwire.ca/#fitText i was succesful on making one but that is about it it only makes a circle i cant make more designs something is wrong with my code can someone please help? also how can i make wedge text and "wiggle" text one last thing i would also like to know how to make spiral text if some one knows any of these it would be a great help



$("#fs").change(function() {
//alert($(this).val());
$('.changeMe').css("font-family", $(this).val());

});

$("#size").change(function() {
$('.changeMe').css("font-size", $(this).val() + "px");
});







$("#demo1").click(function(){ $('.changeMe').circleType("fitText:true", $(this).attr('radius: 180')); });

Answer

My guess is that your problem is with this code:

   $("#demo1").click(function(){
        $('.changeMe').circleType("fitText:true", $(this).attr('radius: 180'));
    });

You do not have a proper div matching this code. I'll come back to this in a minute but first you should know that usually one does not go in and edit a library directly. My suggestion is that you play with your code inside of its own separate <script> tags.

So maybe after you finish loading your libraries:

<script>
$("#fs").change(function() {
    //alert($(this).val());
    $('.changeMe').css("font-family", $(this).val());
});

$("#size").change(function() {
    $('.changeMe').css("font-size", $(this).val() + "px");
});

$("#demo1").click(function(){
    $('.changeMe').circleType("fitText:true", $(this).attr('radius: 180'));
});
</script>

Then you just need to modify your HTML so that you have a demo1 div that is not a button:

<div id="demo1">Here is some text I would like to see in a different shape.</div>

This code probably likes to run against regular old HTML text and not a button.

Hope this helps!
