Multi jQuery Sliders, Help me write this in better code
When you have code that repeats itself like that, you want to try and separate the logic from the values. Something like this would work, and you just have to add more to the settings object when needed. It's not jQuery that's badly written, you just have to change the way you're using it. http://jsfiddle.net/Sqg8A/5/

$(function() {
    var settings = {
        "yield" : {
            range: true,
            min : 15.2,
            max : 308,
            step : 0.3,
            values : [75.8, 241.4]
        },
        "tensile" : {
            range: true,
            min : 37.7,
            max : 345,
            step : 0.3,
            values : [81.2, 243.3]
        },
        "elongation" : {
            range: true,
            min: 1.0,
            max: 77,
            step: 0.1,
            values: [14.5, 43.2]
        } //Add more if needed
    }

    $.each(settings, function(key, value){
        var _key = key;
        $( "#" + _key ).slider(
            $.extend(value, { 
                slide: function( event, ui ) {
                    $( "#" + _key + "-value" ).val( ui.values[ 0 ] + " - " + ui.values[ 1 ] );
                }
            })
        );
        $( "#" + _key + "-value" ).val( $( "#" + _key ).slider("values", 0) + " - " + $( "#" + _key ).slider("values", 1));
    });
});
