title: jQuery UI Slider - disable sliding on track/enable on handle mousedown
body: <p>I have a jQuery UI Slider, which I want to disable when a user tries to slide using the track. It should only work/enable when someone drags the handle somewhere. Clicking and trying to drag the sliding to move the handle should be disabled. I'm not sure if this can be done using <code>unbind</code> or <code>mousedown</code> event.</p>
  
  <p>The problem I notice is, my handle goes from 1 to 100. When you move the start of the handle, it displays uses the <code>ui.value</code>. But if you try to go outside the handle and slide on the slider track, the <code>ui.value</code> resets its value. </p>
  
  <p>So, I want to disable non-handle dragging.</p>
