jquery progress bar : non determinate one
I am using jQuery progress bar. However I want to use it more like a spinner. I can't really predict when the task will complete. So I need a non determinate progress bar.
jQuery UI progress bar only works when you know how much is done. Is is it possible to use jQuery UI progress bar in such a way that when bar reaches 100% then it starts again.
I have everything theme rolled so it would be nice if I could make jquery UI progress bar work rather than using a dif开发者_运维知识库ferent plugin.
As a matter of UI design, please don't change the value of a determinate progress bar to represent an indeterminate one: it's very irritating to see a progress bar apparently going to completion and “... nope! fooled ya!” Indeterminate progress bars on both Mac OS X and Windows have distinct visual representations, and so should yours.
http://www.ajaxload.info/ lets you create several types of customized indeterminate progress bars and spinners. If you really want to use jQuery I guess you could make a custom theme that uses an animated spinner type background for the progress bar.
You could set a timeout to increase the progress bar value by 5% every few seconds and if it reaches 100% start from 0 .. or reverse the increment to -5% so it goes up and down ...
something like
function progressTimeout() {
setTimeout(
function(){
var pbar = $("#progressbar");
var pvalue = pbar.progressbar('option','value');
if (pvalue == 100) pvalue = 0;
pbar.progressbar('option', 'value',pvalue + 10);
if (!/*check if action is complete*/)
setTimeout( progressTimeout, 2000 );
},
2000
);
}
