Getting Started

#### Install it

Include material-refresh.min.js and material-refresh.min.css in your target html file.

``html



`

Cause it is a plugin for Zepto or jQuery, so we also need to include Zepto or jQuery:
`html




`

Usually, we will combine and compress all the css or js, depend on your needs.

You can also install it via Bower or npm:

`
bower install --save material-refresh
`
`
npm install --save material-refresh
`

Basic usage

Example for Type1: Above surface (default):

1.Instantiation:

`js
mRefresh();
`

2.Finish the refresh and hide it:

`js
mRefresh.resolve();
`

Relations of three types

* Type1 and Type2 can not use in the same time.
* Type3 is depend on Type1 or Type2, cause it will determine the refresher position
* Type3 and (Type1 or Type2) can use in the same time.

Advanced usage

#### Options

`js
// Default options
/ var opts = { /
/ nav: '', //String, using for Type2 /
/ scrollEl: '', //String /
/ top: '0px', //String /

mRefresh(opts);
`

##### nav:

-- Using for turn into Type2, refresh body will below the nav surface

`js
// Example
var opts = {
nav: '#navMain'
}
`

##### scrollEl:

-- Custom scroll wrapper element, decide which elemnt will allow trigger refresh action.

-- Default:{ ios:document.body, android: document }

`js
var opts = {
scrollEl: '#mainWrapper'
}
`

##### onBegin: (Callback Function)

-- Trigger when the refresh body start to rotate because of the right gesture(swipe).

-- You can use this callback to pull ajax data or other action.

`js
var opts = {
onBegin: function(){
alert('Begin to rotate');
$.get('/whatevs.html', function(response){
$('#someDom').append(response);
});
}
}


##### onEnd: (Callback Function)

-- Trigger when finished the refresh

-- Using like onBegin

##### top:

-- Set top of the refresher.

-- You can change its position finally by setting this option.

-- Default{ Type1 :'0px', Type2: depend on the height and top of the nav element }

`js
var opts = {
top: '50px'
}
`

##### index:

-- Set z-index of the refresher to change it in z-space.

-- Default { Type1: 10001, Type2: (the z-index of nav element) - 1}

`js
var opts = {
index: 99
}
`

##### theme: (Default: 'mui-blue-theme')

-- Set color or custom style of the refresher.

-- You can write your own style in css file by using the className like 'mui-somecolor-theme'

`js
var opts = {
theme: 'mui-red-theme'
}
`

##### maxTime: (Default: 6000ms)

-- Refresher will stop in the maxTime if you don't use mRefresh.resolve() to stop it.

-- You can change this maxTime to make it longer or shorter.

`js
var opts = {
maxTime: 2000
}
`

##### freeze: (Default: false)

-- The touch event of the refresher will not trigger if freeze is true.

-- You can use this option to prevent Type1 or Type2 and just allow Type3: button action

`js
var opts = {
freeze: true
}
`

#### Type1: Above surface

You can custom your own refresher like:

`js
var opts = {
maxTime: 3000,
onBegin: function(){
$.get('/whatevs.html', function(response){
$('#someDom').append(response);
});
},
onEnd: function(){
alert('Finish the refresh');
}
}

mRefresh(opts);
`

#### Type2: Below surface

Use Type2 by setting the option nav to the top of the elements:

`js
// example
var opts = {
nav: '#navMain',
onBegin: function(){
$.get('/whatevs.html', function(response){
$('#someDom').append(response);
});
}
}

mRefresh(opts);
`

Then the refresher will below the surface of the navMain element.

#### Type3: Button action

If you had inited the refresher,you can bind the DOM event by using:
`js
$('#buttonAction').on('tap', function(){
mRefresh.refresh();
});
`
When you click the buttonAction element, the refresher will show.

If you want to get some callback when start or stop to refresh,by using onBegin or onEnd:

`js
$('#buttonAction').on('tap', function(){
var refreshOpts = {
onBegin: function(){
// Do something
$.get('/whatevs.html', function(response){
$('#someDom').append(response);
});
},
onEnd: function(){
alert('Finish!')
}
}
mRefresh.refresh(refreshOpts);
});

`

If you want not to trigger Type1 or Type2, and just need Type3.

`js
var opts = {
freeze: true
}
mRefresh(opts);

$('#buttonAction').on('tap', function(){
mRefresh.refresh();
});

`

Or
`js
mRefresh();
mRefresh.unbindEvents();

$('#buttonAction').on('tap', function(){
mRefresh.refresh();
});
