1、Vue父组件向子组件传递事件/调用事件
<div id="app">
<hello list="list" ref="child"></hello>
<br />
<button v-on:click="myclick">调用子组件中的方法</button>
</div>
<template id="myT"></template> <script>
Vue.component('hello', {
template: '#myT',
methods: {
clickme: function () {
alert("dd");
}
}
});
var app=new Vue({
el: '#app', methods: {
myclick: function () {
this.$refs.child.clickme();
}
}
});
</script>
如果传递参数，可以使用 props数据
2.子组件调用父组件事件
<div id="app">
<hello list="list" v-on:wzhclick="wzhclick"></hello>
</div>
<template id="myT">
<button v-on:click="childclick">调用父组件的方法</button>
</template>
<script>
Vue.component('hello', {
template: '#myT',
methods: {
childclick: function () {
this.$emit('wzhclick', {a:,b:});
}
}
});
var app=new Vue({
el: '#app',
methods: {
wzhclick: function (data) {
alert("我是父组件,参数"+data.a+";"+data.b);
},
}
});
</script>
子组件通过this.$emit()派发事件，父组件利用v-on对事件进行监听，实现参数的传递
3.两平等组件间的调用
@{
ViewBag.Title = "Index";
}
<link href="~/Content/css/bootstrap-theme.min.css" rel="stylesheet" />
<link href="~/Content/css/bootstrap.min.css" rel="stylesheet" />
<link href="~/Content/css/font-awesome.min.css" rel="stylesheet" />
<script src="~/Content/js/jquery-1.8.2.min.js"></script>
<script src="~/Content/js/bootstrap.min.js"></script>
<script src="~/Scripts/vue.min.js"> </script>
<script src="~/Scripts/axios.min.js"></script>
<style>
</style>
<div id="app">
<wzh></wzh>
<zl></zl>
</div>
<script>
var Event = new Vue();//事件调度器
Vue.component('wzh', {
template: '<div>wzh:<input v-on:keyup="isay" v-model="msg">{{msg}}</div>',
data: function () {
return {
msg:''
}
},
methods: {
isay: function () {
Event.$emit("wzhsay", this.msg);
}
}
});
Vue.component('zl', {
template:'<div>wzh说了：{{wzhmsg}}</div>',
data: function () {
return {
wzhmsg:'',
}
},
mounted: function () {
var me = this;
Event.$on("wzhsay", function (data) {
me.wzhmsg = data;
});
}
});
var app=new Vue({
el: '#app',
});
</script>
new一个调度器来Event来完成，在mounted中监听事件，另一个组件中调用Event.$emit来调用此事件完成调度。
