最近一直在用vue，覺得確實是好用。
一，拿資料的雙向綁定來說吧
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>demo1</title>
</head>
<body>
<p id="app">
{{ name }}
<input type="text" v-model="name">
</p>
</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中的所有資料都是在data中定義的，
el是指的掛載的元素，
watch 是我可以偵測某個數據的變化。
v-model=“name” 就是與data中的name資料綁定，input框中的值變，那麼data中的name也會變，我們可以透過差值操作，也就是{{name}}來看到變化，當然也可以像我一樣打log。都是可以的。
當然這樣也許還不是很實用，官網上也是這麼介紹的，那就說我在工作中是怎麼用的吧
現在我的需求是要得到我表單裡邊的所有value ，我們也許可以
let service = $('.vendor').val();
let vendor = document.getElementsByClassName('vendor')[0].value;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
};<template> <p class="devDesc">
<form class="form-horizontal" role="form" ref="form" id="form">
<p class="form-group">
<label for="vendor" class="col-sm-2 control-label text-left">vendor:</label>
<p class="col-sm-2">
<input type="text" class="form-control vendor" id="vendor" v-model="vendor" control-label name="vendor">
</p>
</p>
<p class="form-group">
<label for="dType" class="col-sm-2 control-label text-left">Type:</label>
<p class="col-sm-2">
<input type="text" class="form-control dType" id="dType" v-model="dType" control-label name="dType">
</p>
</p>
<p class="form-group">
<label for="dDesc" class="col-sm-2 control-label text-left">description:</label>
<p class="col-sm-2">
<input type="text" class="form-control dDesc" id="dDesc" v-model="dDesc" control-label name="dDesc">
</p>
</p>
<!--<serList class="serListPad" :services="services" @services-change="servicesChange">-->
<!--</serList>-->
<!--发现这个serList不用抽出来组件-->
<p 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>-->
<p v-for="service in services">
<service v-for="item in items" :items="items" :service="service" @child-services-change="childServicesChange"></service>
</p>
</p>
</form>
<button class="btn btn-info" @click="commit">commit</button>
<button class="btn btn-success">save</button>
</p>
</template>
