Vue non Sons components by value (Bus / Bus / publish subscribe model / observer mode)
Before we already know the father and son by value. Passed over the value of the parent element, by receiving subassembly props, then you can use.
I have learned the value of inter-generational transfer, layer by layer transfer are realized by props. So, how to pass values between siblings do?
By bus achieved as follows:
<! DOCTYPE HTML> <HTML lang = "EN"> <head> <Meta charset = "UTF-. 8"> <title> </ title> </ head> <body> <div ID = "App"> <Child = Content 'the Dell'> </ Child> <Child Content = 'Lee'> </ Child> </ div> <Script the src = "JS / vue.js"> </ Script> <Script> // for each a bus Vue binding property, in fact, he was a Vue example Vue.prototype.bus = new new Vue () Vue.component ( 'Child', { Data: function () { return { // to avoid directly modify the parent component pass over value, the value of the parent element to a copy of msg: this.content } }, props:{ content:String }, Template: '<div = @ the Click "the handleClick"> {{}} msg </ div>', Methods: { the handleClick: function () { // subassembly change event is triggered to the parent component, while the msg pass over this EMIT $ .Bus ( 'change', this.msg). } }, // this component mount when a function performed mounted: function () { // via bus monitor change event, the event triggered when the change time, the operation var = this_ the this this.bus. $ ON ( 'Change', function (Message) { the console.log (Message) this_.msg = Message }) } }) // 1. Create an instance of Vue let vm Vue new new = ({ EL: '#app', }); </ Script> </ body> </html>
