Jquery click button to automatically highlight implementation principle and code_jquery

In fact, the principle is very simple. When we click, we add a custom attr to the element. After adding it, there will be a matching style to automatically adapt to the background. After a few seconds, remove the style and restore it to its original state

First extend a method hoverEl in your own js

Copy the code The code is as follows:

$ .extend($.fn, {
hoverEl:function(){

var _this = $(this);
var _t = setTimeout(function(){
_this.attr( "hover", "on");
}, 10);
_this.attr("hoverTimeout", _t);

setTimeout(function(){
clearTimeout( _this. attr("hoverTimeout") );
var _t = setTimeout(function(){
_this.removeAttr("hover");
}, 100);
_this.attr("hoverTimeout" , _t);
},200);

}
});

Secondly define the style, when a specific attr is added

Copy code The code is as follows:

li[hover=on]{
background-image:-webkit- gradient(linear, 0% 100%, 0% 0%, from(#194FDB), to(#4286F5))!important;
background-image: -webkit-linear-gradient(top, #4286F5, #194FDB )!important;
color: white!important;
cursor: pointer!important;
}

Call example:

Copy code The code is as follows:

$(e.target).hoverEl();
