How to start

Install it

Include mprogress.min.js and mprogress.min.css in your target html file.

<link rel='stylesheet' href='mprogress.min.css'/>

<script src='mprogress.min.js'></script>

You can also install it via Bower or npm:

bower install --save mprogress

npm install --save mprogress

Basic usage

Example for the Determinate type

1.Instantiation:

var mprogress = new Mprogress();

2.Show and start the bar by using:

mprogress.start();

Or you can just use the following code to replace step 1 and 2:

var mprogress = new Mprogress('start');  //start it immediately

3.Finish the loading and hide it :

mprogress.end();

Advanced usage

All types have start and end methods.

Type1: Determinate

Determinate also has set and inc methods.

set(n)

Sets the progress bar status, where n is a number from 0.0 to 1.0.

eg:

mprogress.set(0.3);

inc()

Increases by a random amount.

eg:

mprogress.inc(); // Increase the bar with a random amount.
mprogress.inc(0.3); // This will get the current status value and adds 0.3 until status is 0.994

Type2: Buffer

Its always used for video loading, and you can use for other case.

Init Type Buffer :

var bufferIntObj = {
  template: 2
};
var bufferProgress = new Mprogress(bufferIntObj);

Start it:

bufferProgress.start();

If you want to start it immediately after instantiating it，you can use:

var bufferIntObj = {
  template: 2, // type number
  start: true  // start it now
};
var bufferProgress = new Mprogress(bufferIntObj);

End it:

bufferProgress.end();

Buffer also has set , inc and setBuffer methods

Type Buffer has two progress: main progress and buffer progress.

set(n)

Sets the main progress bar status (0,1)

setBuffer(num)

Sets the buffer progress bar status (0,1)

inc()

Increases by a random amount, including buffer bar.

Type3:Indeterminate

Init Type Indeterminate :

var intObj = {
  template: 3, 
  parent: '#customId' // this option will insert bar HTML into this parent Element 
};
var indeterminateProgress = new Mprogress(intObj);

Type Indeterminate just has start and end methods.

indeterminateProgress.start();

indeterminateProgress.end();

Type4:Query Indeterminate and Determinate

Init Type Query :

var intObj = {
  template: 4,
  parent: '#anothercustomId' // to other position
};
var queryProgress = new Mprogress(intObj);

Type Query just has start and end methods.

queryProgress.start();

queryProgress.end();
