jQuery progress timer bar

Solution 1

Fiddle Example

I would do something like:

var start = new Date();
var maxTime = 835000;
var timeoutVal = Math.floor(maxTime/100);
animateUpdate();

function updateProgress(percentage) {
    $('#pbar_innerdiv').css("width", percentage + "%");
    $('#pbar_innertext').text(percentage + "%");
}

function animateUpdate() {
    var now = new Date();
    var timeDiff = now.getTime() - start.getTime();
    var perc = Math.round((timeDiff/maxTime)*100);

    if (perc <= 100) {
        updateProgress(perc);
        setTimeout(animateUpdate, timeoutVal);
    }
}

Solution 2

Simply do some good old fashioned math. It doesnt seem right because you're giving width percentage as the value of the "tick" which will eventually be 835000! Meaning you eventually have a width of "835000%"!!!

Example

var timer = 0,
    perc = 0,
    timeTotal = 835000,
    timeCount = 50;

function updateProgress(percentage) {
    var x = (percentage/timeTotal)*100,
        y = x.toFixed(3);
    $('#pbar_innerdiv').css("width", x + "%");
    $('#pbar_innertext').text(y + "%");
}

function animateUpdate() {
    if(perc < timeTotal) {
        perc++;
        updateProgress(perc);
        timer = setTimeout(animateUpdate, timeCount);
    }
}

$(document).ready(function() {
    $('#pbar_outerdiv').click(function() {
        clearTimeout(timer);
        perc = 0;
        animateUpdate();
    });
});

jsFiddle Demo

Description

This just simply increases the progress every 10ms...since you know the time it takes, take that time and divide by 100 then make that your timeinterval in var timer = setInterval(updateProgressbar, 10);

HTML

<div id="progressbar"></div>

JS

var progress = 0;
var timer = setInterval(updateProgressbar, 10);

function updateProgressbar(){
    $("#progressbar").progressbar({
        value: ++progress
    });
    if(progress == 100)
        clearInterval(timer);
}

$(function () {
    $("#progressbar").progressbar({
        value: progress
    });
});

JS Fiddle Just for you

JS

var progress = 0;
var timer = setInterval(updateProgressbar, 8350);

function updateProgressbar(){
    $("#progressbar").progressbar({
        value: ++progress
    });
    if(progress == 100)
        clearInterval(timer);
}

$(function () {
    $("#progressbar").progressbar({
        value: progress
    });
});

    I have a progress timer bar in jQuery - here is an example http://jsfiddle.net/6h74c/

    If I have time values in milliseconds, (600000 = 10 minutes, 300000 = 5 minutes, etc), how can I make the bar increment for that period of time?

    In the jsfiddle link, I'm trying to set the progress bar to increase for 835000ms.

    However, the setTimeout() determines how often the bar will increase and it is also basing it off of width percentage, which doesn't seem accurate - should I be doing this differently?

    function updateProgress(percentage) {
        $('#pbar_innerdiv').css("width", percentage + "%"); // probably not ideal
        $('#pbar_innertext').text(percentage + "%");
    }
    
    function animateUpdate() {
        perc++;
        updateProgress(perc);
        if(perc < 835000) {
            timer = setTimeout(animateUpdate, 50); // probably not ideal either?
        }
    }
