Track the distance between the mouse cursor and multiple elements

install

bower:

bower install mouse-proximity

npm:

npm install mouse-proximity

distribution file: dist/js/mouse-proximity.min.js

Use with vanilla js

//initialize options here
var mprox = new mouseProximity(document.getElementsByClassName('demo'), {
    clear: true,
    origin: 'center',
    showAttribute: false,
    cb: //callback can be set here too
});

//callback
var doSomething = function(el,distance){
    //do something with the element (el)
    //dow something with the distance (distance)
}

//run the proximity tracker
mprox.run(doSomething);

//stop the proximity tracker
mprox.stop();

Use with jQuery

//initialize options here
$('.demo').mouseProximity({
    clear: true,
    origin: 'center',
    showAttribute: false,
    cb: //callback can be set here too
});

//callback
var doSomething = function(el,distance){
    //do something with the element (el)
    //dow something with the distance (distance)
}

//run the proximity tracker
$('.demo').data('mouseProximity').run(doSomething);

//stop the proximity tracker
$('.demo').data('mouseProximity').stop();

Options

clear

• type: boolean
• default: false
• for clearing the console so you don't end up with a huge list of mouse move logs (not really reliable)

origin

• type: string
• options: center (only one option for now)
• default: center
• set the origin relative to the body of the element from which to calculate distance from the mouse cursor

showAttribute

• type: boolean
• default: true
• add a data-mouse-proximity attribute to the element with its distance data

cb

• type: function
• default:

function(el,distance){
    console.log(el.outerHTML + ', distance ' + distance);
}

• callback function for doing whatever you want with the resulting distance data

Methods

run( callback( el, distance) )

starts a mousemove event and feeds the resulting data into the callback

stop()

unbinds the mousemove event and halts proximity tracking
