vue2.0数据双向绑定与表单bootstrap+vue组件
最近一直在用vue,觉得确实是好用。
一,拿数据的双向绑定来说吧
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo1</title> </head> <body> <div id="app"> {{ name }} <input type="text" v-model="name"> </div> </body> <script type="text/javascript" src="vue.js"></script> <script> new Vue({ el: '#app', data: { name: '' }, watch: { name: function () { console.log(this.name); } } }); </script> </html>
vue中的所有数据都是在data中定义的,
el是指的挂载的元素,
watch 是我可以检测某个数据的变化。
v-model=“name”
就是与data中的name数据绑定,input框中的值变,那么data中的name也会变,我们可以通过差值操作,也就是{{name}}来看到变化,当然也可以像我一样打log。都是可以的。
当然这样也许还不是很实用,官网上也是这么介绍的,那么就说我在工作中是怎么用的吧
现在我的需求是要得到我表单里边的所有value ,我们也许可以
let service = $('.vendor').val(); let vendor = document.getElementsByClassName('vendor')[0].value;
但是这样就完全没有get到vue双向绑定的好处了,那么我们该怎么做呢?
import service from './components/service.vue'; import $ from 'jquery'; export default { data () { return { resultData: '', vendor: '', dType: '', services: [service], items: [service], device: '', dDesc: '' } }, watch: { services () { console.log(this.services); }, items (val) { this.items = val; console.log(this.items); } }, components: { service }, methods: { addService (component) { this.items.push(component); }, childServicesChange (val) { this.services = val; }, commit () { console.log('commit'); let device = { "type": 'urn:' + this.vendor + ':device:' + this.dType + ':0000', "description": this.dDesc, "services": this.items };
看到没,我就是直接用的this.vendor, vendor是在data中定义好的,也进行了双向绑定v-model
<template> <div class="devDesc">
Device Description
<form class="form-horizontal" role="form" ref="form" id="form"> <div class="form-group"> <label for="vendor" class="col-sm-2 control-label text-left">vendor:</label> <div class="col-sm-2"> <input type="text" class="form-control vendor" id="vendor" v-model="vendor" control-label name="vendor"> </div> </div> <div class="form-group"> <label for="dType" class="col-sm-2 control-label text-left">Type:</label> <div class="col-sm-2"> <input type="text" class="form-control dType" id="dType" v-model="dType" control-label name="dType"> </div> </div> <div class="form-group"> <label for="dDesc" class="col-sm-2 control-label text-left">description:</label> <div class="col-sm-2"> <input type="text" class="form-control dDesc" id="dDesc" v-model="dDesc" control-label name="dDesc"> </div> </div> <!--<serList class="serListPad" :services="services" @services-change="servicesChange">--> <!--</serList>--> <!--发现这个serList不用抽出来组件--> <div class="serList serListPad"> <section class="serList-section"> <span class="span-serList">service List</span> <button type="button" class="btn btn-default btn-sm" @click="addService(service)"> <span class="glyphicon glyphicon-plus"></span> </button> </section> <!--<service v-for="item in items" :items="items" :myService="myService" @child-services-change="childServicesChange"></service>--> <div v-for="service in services"> <service v-for="item in items" :items="items" :service="service" @child-services-change="childServicesChange"></service> </div> </div> </form> <button class="btn btn-info" @click="commit">commit</button> <button class="btn btn-success">save</button> </div> </template>
