I have this JS:
$(".play").mouseenter(function() {
$( ".glitch-img" ).mgGlitch({
// set 'true' to stop the plugin
destroy : false,
// set 'false' to stop glitching
glitch: true,
// set 'false' to stop scaling
scale: true,
// set 'false' to stop glitch blending
blend : true,
// select blend mode type
blendModeType : 'hue',
// set min time for glitch 1 elem
glitch1TimeMin : 200,
// set max time for glitch 1 elem
glitch1TimeMax : 400,
// set min time for glitch 2 elem
glitch2TimeMin : 10,
// set max time for glitch 2 elem
glitch2TimeMax : 100,
});
}).mouseleave(function() {
$( ".glitch-img" ).mgGlitch({
destroy : true, // set 'true' to stop the plugin
});
});
And my HTML is like this:
<div>
<figure>
<div class="glitch-img" style="background-image: url('assets/images/image.jpg')"></div>
</figure>
</div>
<div>
<div class="play play1"></div>
</div>
I don't know how to make my mouseenter work just on the current .play
-element without affecting all the other .play
-elements.
If I get you right you actually want to target the .glitch-img
-element which you can target like showen below (I also refactorized your code):
handleGlitch = function( oEvent )
{
// build the right configuration based on mouseenter/mouseleave
oGlitch = oEvent.handleObj.origType == 'mouseleave'
? { destroy : true } // config for "mouseleave"
: { destroy : false, // config for "mouseenter"
glitch : true,
scale : true,
blend : true,
blendModeType : 'hue',
glitch1TimeMin: 200,
glitch1TimeMax: 400,
glitch2TimeMin: 10,
glitch2TimeMax: 100 };
// lets first get the element that triggered the event which is "div.play"
// oEvent.target is the dom element on which the mouseenter/mouseleave event was fired
$Play = $( oEvent.target ); // you can now do eg: $Play.addClass('active')|$Play.removeClass('active')
// so now we have to target the right "div.glitch-img"
// and not every "div.glitch-img" like it was before
$Play
.parent() // get parent element of "div.play"
.prev() // get the previous element of that parent
.find('.glitch-img') // now find the element with class "glitch-img"
.mgGlitch( oGlitch ) // and do your glitchi stuff
}
// attache event handlers
// event object will be passed as an argument to handleGlitch function
$(".play").mouseenter( handleGlitch ).mouseleave( handleGlitch );
<div>
<figure>
<div class="glitch-img" style="background-image: url('assets/images/image.jpg')"></div>
</figure>
</div>
<div>
<div class="play play1"></div>
</div>
<div>
<figure>
<div class="glitch-img" style="background-image: url('assets/images/image.jpg')"></div>
</figure>
</div>
<div>
<div class="play play2"></div>
</div>
Edit/Recommendation
If you are able to I would strongly suggest to refactorize your markup. While my answer may helped you out with your current issue the
$( oEvent.target ).parent().prev().find('.glitch-img')
part will probably fail as soon as you just change an itty bitty on your current markup as it strongly relies on the structure of your markup which is a bad practice in general. So I would do something like:
<div>
<figure><!-- note the add of the id "glitch-1" which correspondents to "play-1" -->
<div id="glitch-1" class="glitch-img" style="background-image: url('assets/images/image.jpg')"></div>
</figure>
</div>
<div><!-- note the add of the id "play-1" which correspondents to "glitch-1" -->
<div id="play-1" class="play"></div>
</div>
<div>
<figure><!-- note the add of the id "glitch-2" which correspondents to "play-2" -->
<div id="glitch-2" class="glitch-img" style="background-image: url('assets/images/image.jpg')"></div>
</figure>
</div>
<div><!-- note the add of the id "play-2" which correspondents to "glitch-2" -->
<div id="play-2" class="play"></div>
</div>
Now the structure of your markup is independent from the relation of #play-[nr]
to #glitch-[nr]
as long as you keep the pattern.
handleGlitch = function( oEvent )
{
// now you can target your elements much more reliable and also more efficiently
// lets get the number out of our "div.play" elment by its id
sId = oEvent.target.id // eg: "play-1", "play-2"
sNr = sId.substr( 1 + sId.indexOf('-') ) // eg: "1", "2"
// now its easy to target the glitch element with vanilla JS
document.getElementById( 'glitch-' + sNr )
// but while you want to do some jQuery-mgGlitch-stuff you can do so by
$( '#glitch-' + sNr ).mgGlitch( oGlitch )
}
$(".play").mouseenter( handleGlitch ).mouseleave( handleGlitch );
Or with other words: you can now change your markup as you like without touching the JavaScript part anymore which is a very good thing. Isn't it?
