react-sortable-mixin2 v0.0.6

react-sortable-mixin

Based on react-sortable-mixin

A mixin for React to creat a sortable(drag and move) List Component. Demo

Install

npm install --save-dev react-sortable-mixin

Usage

• Define a List Component use ListMixin contains Item Components use ItemMixin.
• List Component required state items to set items' data or implement method "onGetItems" which will return array to be used for sorting
• List Component must implemtn "onResort" method which should update state of list compoenent as per requirement. NOTE: State is now not updated implicitly, so if onResort does not update state, list will go back to original state on drag end.
• Item Component required props: key / index / movableProps.
• Item component can have "handle" property, which has selector for handler element.. In that case handler element will be used to initiate drag. eg handle=".drag-handle"

That's it!

Example code:

var React = require('react');
var sortable = require('react-sortable-mixin');

// Item Component use `ItemMixin`
var Item = React.createClass({
  mixins: [sortable.ItemMixin],
  render: function() {
    return <li><span className="drag-handle" >Move</span> item {this.props.item}</li>;
  }
});

// List Component use `ListMixin`
var List = React.createClass({
  mixins: [sortable.ListMixin],
  componentDidMount: function() {
    // Set items' data, key name `items` required
    this.setState({ items: this.props.items });
  },
  render: function() {
    var items = this.state.items.map(function(item, i) {
      // Required props in Item (key/index/movableProps)
      return <Item handle=".drag-handle" key={item} item={item} index={i} {...this.movableProps}/>;
    }, this);

    return <ul>{items}</ul>;
  },
  onResort: function(items, oldposition, newposition){
    this.setState({ items: items });
  }
});

module.exports = List;
