.self can be understood as skipping bubble events and capturing events, and only events that act directly on this element can be executed.
The code is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>self</title>
<script src=""></script>
<!--'''''''''''''''''''Please introduce it yourself-->
</head>
<style type="text/css">
* {
margin: 0 auto;
text-align:center;
line-height: 40px;
}
div {
width: 100px;
}
#obj1 {
background: deeppink;
}
#obj2 {
background: pink;
}
#obj3 {
background: hotpink;
}
#obj4 {
background: #ff4225;
}
</style>
<script src=""></script>
</head>
<body>
<!--Clickobj4It will be displayed separately when： obj4、 obj3、 obj1；
.selfIt will monitor whether the event is directly affectedobj2superior，If not，Then bubbling and skipping the element，-->
<div >
<div v-on:click="doc">
obj1
<div v-on:="doc">
obj2
<!--只有Clickobj2才可以出发其Click事件。-->
<div v-on:click="doc">
obj3
<div v-on:click="doc">
obj4
</div>
</div>
</div>
</div>
</div>
<script type="text/javascript">
var content = new Vue({
el: "#content",
data: {
id: ''
},
methods: {
doc: function () {
= ;
alert()
}
}
})
</script>
</body>
</html>
The above article is based on the usage of self (detailed explanation) based on the event modifier in China. I hope it can give you a reference and I hope you can support me more.
