Disable Buttons

Disable Buttons

I am trying to disable buttons after the page loads. The code is located in an linked script but when the $(document).ready section:

$(document).ready(function () {
      $("#btnMoveDesigns").button({
        disabled: true
    });
});

When I hit the above code I get on 'Object doesn't support property or method 'button''.

The jquery.js, jquery-ui.js and jquery-ui.css are all linked in a masterpage that the page calling the .button reference is using.

I cannot supply a jsfiddle example but if anyone has any ideas how to approach/resolve this issue I would appreciate the help.
