具有类名单击事件的按钮不起作用

Question

I have button with class name of "sldprv" but when in doucment ready I checked that button with class clicked or not. its not working and i am getting this error in chrome. and in fire fox it's not even working

        $(".sldprv").click(function(e) {
             alert('click');
             e.preventDefault();
         });

but with button Id it is working.

I know there's too little basic I have missed but I can't see god!!

[edited] To explain you bit more on this...

I am working this code with Jquery Wizard that I am adding this class to the previous button only in the first step and removing that after follow the lines of code edited in the plug in js

       if ( state.isFirstStep || o.unidirectional ||
        state.step.hasClass( o.stepClasses.unidirectional ) ) {
        //TO DO: back to slide
        this.elements.backward.addClass("sldprv");
    } else {

        this.elements.backward.removeAttr( disabled );
        this.elements.backward.removeClass("sldprv");
    }

so that I can catch the previous button only at the first step and do my own animation

Hope you guys got the idea and what the issues is.

Look this: http://jsfiddle.net/fXb6s/1/ . I just add jQuery as lib for it.

$(document).ready(function() {
         $(".sldprv").click(function(e) {
             alert('click');
             e.preventDefault();
         });
});
