Combined total for multiple jQuery-UI Sliders

Well here ya go:

var sliders = $("#sliders .slider");

sliders.each(function() {
    var value = parseInt($(this).text(), 10),
        availableTotal = 400;

    $(this).empty().slider({
        value: 0,
        min: 0,
        max: 400,
        range: "max",
        step: 10,
        slide: function(event, ui) {
            // Update display to current value
            $(this).siblings().text(ui.value);

            // Get current total
            var total = 0;

            sliders.not(this).each(function() {
                total += $(this).slider("option", "value");
            });

            // Need to do this because apparently jQ UI
            // does not update value until this event completes
            total += ui.value;

            var max = availableTotal - total;

            // Update each slider
            sliders.not(this).each(function() {
                var t = $(this),
                    value = t.slider("option", "value");

                t.slider("option", "max", max + value)
                    .siblings().text(value + "https://stackoverflow.com/" + (max + value));
                t.slider('value', value);
            });
        }
    });
});

Here’s a simple demo of this: http://jsfiddle.net/yijiang/Y5ZLL/4/

Made an updated version of the above answer to show percentages of 100%. So as you adjust one slider up, the other two decrease making the percentage of each slider add up to 100%. Also made it easy to set initial values

JSfiddle

var sliders = $("#sliders .slider");
var availableTotal = 100;

sliders.each(function() {
    var init_value = parseInt($(this).text());

    $(this).siblings('.value').text(init_value);

    $(this).empty().slider({
        value: init_value,
        min: 0,
        max: availableTotal,
        range: "max",
        step: 2,
        animate: 0,
        slide: function(event, ui) {

            // Update display to current value
            $(this).siblings('.value').text(ui.value);

            // Get current total
            var total = 0;

            sliders.not(this).each(function() {
                total += $(this).slider("option", "value");
            });

            // Need to do this because apparently jQ UI
            // does not update value until this event completes
            total += ui.value;

            var delta = availableTotal - total;

            // Update each slider
            sliders.not(this).each(function() {
                var t = $(this),
                    value = t.slider("option", "value");

                var new_value = value + (delta/2);

                if (new_value < 0 || ui.value == 100) 
                    new_value = 0;
                if (new_value > 100) 
                    new_value = 100;

                t.siblings('.value').text(new_value);
                t.slider('value', new_value);
            });
        }
    });
});
