API
Calling the draggable() function returns a Draggable instance:
const d = draggable(elm);It has the following methods:
.enable() / .disable()
Toggle draggability. When disabled, the main element gets a 'drag-disabled' classname.
.setGrip(newGrip)
Sets a new grip handle. Argument could be either an HTML Element or an element selector string (e.g. '#my-grip'). See the grip option above.
.on(eventName, callback)
Listen to drag and drop events:
'drag-start'- dragging started, on mouse down.'dragging'- moving around, on mouse move (with mouse down)'drag-stop'- dragging stopped, on mouse up.
Event Aliases
For extra convenience, anything that contains start, stop/end/drop or ing will match its respective event.
.moveTo({top, left, bottom, right})
Sets the element position. The argument is an object containing one or more of the positioning properties:
topleftbottomright
topandleftare preferred overbottomandright, respectively.
.destroy()
Kills the Draggable instance for good, unbinds events, releases element references.
Classnames
For styling, the main element will be given the following classes:
'draggable'- from initialization until destruction.'dragging'- on mouse down, until mouse up.
Any element that is set as a grip handle will be given the classname: 'drag-grip-handle'.
Position:
On initialization, the target element will be placed inside the
<body>element and will be given an inline style ofposition: absolute.
