语法
<div id="app">
<h1>{{ title }}</h1>
<div>
<span>{{ views+1 }}</span>
<span>{{ type ? '原创' : '转载' }}</span>
</div>
</div>
<script>
var vm = new Vue({
el:'#app',
data:{
title : 'hello',
views : 1152,
type : true
}
});
</script>
指令
<div id="app">
<!-- HTML输出 -->
<div v-html="content"></div>
<a v-bind:href="home"></a>
<!-- 简写 -->
<a :href="home"></a>
<button v-on:click="notice">提示</button>
<!-- 简写 -->
<button @click="notice">提示</button>
<p>{{copyright()}}</p>
</div>
<script>
var vm = new Vue({
el:'#app',
data:{
content : '<ul class="list-unstyled"><li>列表1</li><li>列表2</li></ul>',
home:'/home',
company: 'Xcxxkj'
},
methods:{
notice:function(event){
alert('notice message');
},
copyright:function(event){
return 'Copyright '+this.company
}
}
});
</script>
计算属性
<div id="app">
<div>{{ number }}</div>
<div>{{ formatNumber }}</div>
<div>{{ fullName }}</div>
</div>
<script>
var vm = new Vue({
el: "#app",
data: {
number:7,
firstName : "Jone",
lastName: "Doe"
},
computed: {
formatNumber:function(){
return 'No. '+this.number+' ,';
},
fullName:{
get:function(){
return this.firstName+' '+this.lastName;
},
set:function(val){
var names = val.split(' ');
this.firstName = names[0];
this.lastName = names[names.length-1];
},
}
},
});
vm.fullName = "Tom Tone";
</script>
条件判断,循环
<div id="app">
<div v-if="status">根据status显示</div>
<div v-show="status">根据status显示</div>
<div v-if="score > 90">优秀</div>
<div v-else-if="score > 80">良好</div>
<div v-else>努力</div>
<ul>
<li v-for="(item,index) in lists">{{item.name}}</li>
</ul>
<ul>
<li v-for="(value,key) in information">{{key}}-{{value}}</li>
</ul>
</div>
<script>
var vm = new Vue({
el:"#app",
data:{
status: true,
score:75,
lists:[{name:'jim'},{name:'lili'},{name:'tom'}],
information:{nickname:'石武',age:18}
}
});
</script>
Class,Style
<div id="app">
<div class="box" style="font-size:38px;"
v-bind:class="{'box-active':isActive,'box-title':true}"
v-bind:style="{'padding':boxPadding,'color':'red'}">
样式
</div>
<code>
{'box-active':true,'box-title':true} 可简写为 ['box-active','box-title']
</code>
</div>
<script>
var vm = new Vue({
el:'#app',
data:{
isActive:true,
boxPadding:'20px',
}
});
</script>
事件处理
<div id="app">
<input name="publish_time" v-bind:readonly="isReadonly" :disabled="isDisabled">
<br>
<input v-on:click="buttonClick" @keyup.enter="buttonEnter">
</div>
<script>
var vm = new Vue({
el:'#app',
data:{
isReadonly:false,
isDisabled:true,
buttonText:"按钮T",
},
methods:{
buttonClick:function(){
console.log('点击了');
},
buttonEnter:function(){
console.log('回车了')
