Meteor Drag Event

What's that?

This package extend Meteor Blaze Events to support drag event.

Now you can use drag event just like you would use click event on the events template helpers.

Demo

Installation

$ meteor add grmmph:meteor-drag-event

Usage

When using the drag event, the first event argument for the event handler callback will include a drag object with

• type <string>: dragstart, dragend and dragging
• dx<Number>: Difference between last x and current x
• dy<Number>: Difference between last y and current y

Example

Template.hello.events({
  'drag .my-draggable-element': function (evt) {

    if (evt.drag.type === 'dragstart') {
      console.log('You start dragging!')
    } else if (evt.drag.type === 'dragend') {
      console.log('You stopped dragging!')
    } else if (evt.drag.type === 'dragging') {
      console.log('You are dragging!')
    }

    // Move elements in space (element must have position: absolute)
    $(evt.target).animate({
      left: '+=' + evt.drag.dx,
      top: '+=' + evt.drag.dy,
    }, 1);
  }
});
