Question

I need a jquery slider with two handles with inputs from two textbox like this http://www.israel-diamonds.com/search/diamonds/default.aspx .Currently i have a single handle slider with input from a single textbox

$("#slider").slider({
    value: 1,
    step: 1000,
    min: 0,
    max: 5000000,
    slide: function(event, ui) {
        $("input").val("$" + ui.value);
    }
});
$("input").change(function () {
    var value = this.value.substring(1);
    console.log(value);
    $("#slider").slider("value", parseInt(value));
});

Any suggestion?

        <div id="slider"></div>
    </div>

and

  $("#slider").slider({
        range: "min",
        value: 1,
        step: 10,
        min: 0,
        max: 1000,
        slide: function (event, ui) {
            $("input").val(ui.value);
        }
    });


    $("input").change(function (event) {
        var value1 = parseFloat($("input").val());
        var highVal = value1 * 2;
        $("#slider").slider("option", { "max": highVal, "value": value1 });
    });

Solution

Assuming you have two <input> elements:

<input type="text" class="sliderValue" data-index="0" value="10" />
<input type="text" class="sliderValue" data-index="1" value="90" />

And a slider placeholder element:

<div id="slider"></div>

You can use the values option to put the slider widget in multiple handle mode, and synchronize the values of the <input> elements with:

$("#slider").slider({
    min: 0,
    max: 100,
    step: 1,
    values: [10, 90],
    slide: function(event, ui) {
        for (var i = 0; i < ui.values.length; ++i) {
            $("input.sliderValue[data-index=" + i + "]").val(ui.values[i]);
        }
    }
});

$("input.sliderValue").change(function() {
    var $this = $(this);
    $("#slider").slider("values", $this.data("index"), $this.val());
});
