jQuery is not finding elements

Question

jQuery is not finding any elements. alert($(\"#testbutton\").length); displays 0 every time.

Am I doing something wrong?

My JS / jQuery cod

Answer 1

If you write jQuery script in the head using:

(function() {

    ...

})();

it doesn't work because it may execute the script before loading the content of the body page.

Use:

$(document).ready(function() {

    ...

});

or move your script at the footer.
