This website, http://www.ukgoldrefiners.co.uk/ under the top right window "HOW MUCH IS GOLD WORTH?" there are three sliders that estimate what the current gold price is. Its obvious it uses a formula that multiplies the weight of gold by the current gold price (taken from and external source) of the various carats.
If I manipulate this for my own project :- I have three or more sliders and I can select a value between 1 to 100 and the live number is an average of all the numbers on the slider. e.g
Rating 1: 1-------|--100 (70)
Rating 2: 1-------|--100 (70)
Rating 3: 1-------|--100 (70)
So the average would be 70 and if I manipulate the slider it would change the average number.
My question would be what would this be called? What would I use to make this, JQuery, Java, HTML? Is there any resources?
Click here for an excellent jQuery slider. I've used it before and it includes lots of functionality for event functions such as change which you can use to do your calculation.
Your html would look something like:
<div id="slider1"></div>
<div id="slider2"></div>
<div id="slider3"></div>
<div id="average"></div>
And you would initialize each of the slider div's with something like this:
$("#slider?").slider({
change: function(event, ui) {
//average out the values of all 3 and set the value of 'average' to the averages.
}
});
