I'm using jquery - Filamentgroup slider. I want to limit the slider movement.

Javascript

$('select#valueA, select#valueB').selectToUISlider({
			sliderOptions: {
					change:function(e, ui) {
						return false;
						
					}
			},
			labels: 12
		});

HTML

<fieldset>
		<label for="valueA">From:</label>
		<select name="valueA" id="valueA">
			<option value="6am">6:00</option>
			<option value="7am">7:00</option>
			<option value="8am">8:00</option>
			<option value="9am" selected="selected">9:00</option>
			<option value="10am">10:00</option>

How can i control slider movement. That means if anyone move the slider some position, i need to pragmatically move the slider to particular position.

How can i do that?

Not quite positive what you're trying to achieve, but taking a look at the code samples from the jQuery-UI website for the slider control.

Here's an example from the docs:

Javascript

$(function() {
  $( "#slider-range-min" ).slider({
    range: "min",
    value: 37,
    min: 20,  //valueA
    max: 50,  //valueB
    slide: function( event, ui ) {
      $( "#amount" ).val( "$" + ui.value );
    }
  });
  $( "#amount" ).val( "$" + $( "#slider-range-min" ).slider( "value" ) );
});

HTML

<label for="amount">Maximum price:</label>
<input type="text" id="amount" />
<div id="slider-range-min"></div>

Working demo in Stack Snippets & jsFiddle

<!-- begin snippet: js hide: true console: false babel: false --> <!-- language: lang-js -->
$(function () {
  $("#slider-range-min").slider({
    range: "min",
    value: 37,
    min: 30,
    max: 50,
    slide: function (event, ui) {
      $("#amount").val("$" + ui.value);
    }
  });
  $("#amount").val("$" + $("#slider-range-min").slider("value"));
});
