I am trying to make a drop down menu using jQuery.
This is my HTML:
<div class="overlaydiv">This is my menu!</div>
<div class="row one">
<div class="large-12 columns">
</div>
</div>
<div class="row two">
<div class="large-12 columns">
<button id="b1">Drop down the menu!</button>
</div>
</div>
CSS for overlay:
.overlaydiv { height: 100vh; width: 100vw; background-color: aquamarine; position: absolute; top: -100%; z-index: 1; }
This is jQuery that drops down the menu on click:
$("#b1").on("click", function() {
$(".overlaydiv").animate({top: "0%"}, 200, 'swing');
});
What would be the easiest way to reverse animation on second click?
The best way I can think of is using CSS transition.
So, here's the CSS:
.overlaydiv{
height: 100vh;
width: 100vw;
background-color: aquamarine;
position: absolute;
top: -100%;
z-index: 1;
transition: all 0.2s;
}
.overlaydiv.active{
top: 0%;
}
And the JS
$("#b1, .overlaydiv").on("click", function() {
$(".overlaydiv").toggleClass("active");
});
You can check that to assign class
active on your button and make action on it.
$("#b1").on("click", function() { if($(this).hasClass("active")){ $(this).removeClass("active"); $(".overlaydiv").animate({top: "-100%"}, 200, 'swing'); }else{ $(this).addClass("active"); $(".overlaydiv").animate({top: "0%"}, 200, 'swing'); } });
.overlaydiv { height: 100vh; width: 100vw; background-color: aquamarine; position: absolute; top: -100%; z-index: 1; } #b1 {position:relative;z-index:2}
