Demo

Getting Started

Install it

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

<link rel='stylesheet' href='material-refresh.min.css'/>

<script src='material-refresh.min.js'></script>

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

<script src='zepto.js'></script>

<!-- or include jQuery.js-->
<script src='jQuery.js'></script>

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:

mRefresh();

2.Finish the refresh and hide it:

mRefresh.resolve();

If you don't use this method, refesher will stop after the maxTime(Default: 6000ms).

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

    // Default options 
     var opts = { 
         nav: '', //String, using for Type2 
         scrollEl: '', //String  
         onBegin: null, //Function 
         onEnd: null, //Function 
         top: '0px', //String 
         theme: 'mui-blue-theme', //String 
         index: 10001, //Number
         maxTime: 6000, //Number 
         freeze: false //Boolen 
     } 
    mRefresh(opts);
nav:

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

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

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

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

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.

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 }

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

var opts = {
  theme: 'mui-red-theme'
}
index:

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

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

var opts = {
  index: 99
}
maxTime: (Default: 6000ms)

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

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

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

var opts = {
  freeze: true
}

Type1: Above surface

You can custom your own refresher like:

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:

// 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:

$('#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:

$('#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.

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

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

Or

mRefresh();
mRefresh.unbindEvents();

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