DRY multiple if statements used to show/hide elements based on slider value I'm showing and hiding 4 svg paths based on the value of a slider, all is working as expected, but it still feels a little cumbersome. Does anyone know a way to "DRY" it out a little more?

jsFiddle

$('.volumeSlider').slider({
    value: 1,
    orientation: "vertical",
    range: "min",
    max: 1,
    step: 0.05,
    animate: true,
    slide: function (e, ui) {
        $('p').text(ui.value);
        var v = $('.volume1');
        if (ui.value == 1) {
            v.show();
        }
        if (ui.value &lt; 1) {
            v.slice(0).hide();
            v.slice(1, 4).show();

        }
        if (ui.value &lt;= 0.65) {
            v.slice(0, 2).hide();
            v.slice(2, 4).show();
        }
        if (ui.value &lt;= 0.35) {
            v.slice(0, 3).hide();
            v.slice(4).show();
        }
        if (ui.value === 0) {
            v.hide();
        }
    }
});
I am guessing that the '.volume' elements are like volume indicators, the louder the sound, the more you show.

You can iterate over the '.volume' elements, compare the index / elementCount to ui.value and decide to hide or show per that comparison.

So, something like : 

$('.volumeSlider').slider({
    value: 1,
    orientation: "vertical",
    range: "min",
    max: 1,
    step: 0.05,
    animate: true,
    slide: function (e, ui) {
        $('p').text(ui.value);
        var v = $('.volume1');
        for( var i = 0 ; i &lt; v.length ; i++ ){
            ( 1-ui.value &gt; 1 / v.length * (i + 1)) ? v.slice(i).hide() : v.slice(i).show()
        }
    }
});


should work. This approach will work with any number of volume1 elements.
I did not test this, but once you see/get this I am sure you can make this work.

Further optimizations can be caching v.length and 1 / v.length, you could probably also use eq instead of slice()

EDIT : I fixed the code to work with your HTML, the original was 

( ui.value &lt; 1 / v.length * (i + 1)) ? v.slice(i).hide() : v.slice(i).show()
which would work if the HTML elements were created in what I see as the correct order.
