v-bind示例
<div id="app-2">
<span v-bind:title="message">
鼠标悬停几秒钟查看此处动态绑定的提示信息！
</span>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
var app2 = new Vue({
el: '#app-2',
data: {
message: '页面加载于 ' + new Date().toLocaleString()
}
})
</script>
v-if示例
<div id="app-3">
<p v-if="seen">现在你看到我了</p>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
var app3 = new Vue({
el: '#app-3',
data: {
seen: false
}
})
</script>
v-else示例
<div id="app-3">
<p v-if="seen">This is if</p>
<p v-else>This is else</p>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
var app3 = new Vue({
el: '#app-3',
data: {
seen: false
}
})
</script>
v-else-if示例
<div id="app-3">
<p v-if="seen==='a'">This is if</p>
<p v-else-if="seen==='b'">This is else-if</p>
<p v-else>This is else</p>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
var app3 = new Vue({
el: '#app-3',
data: {
seen: "a"
}
})
</script>
v-for示例
<div id="app-4">
<ol>
<li v-for="todo in todos">
{{ todo.text }}
</li>
</ol>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
var app4 = new Vue({
el: '#app-4',
data: {
todos: [{
text: '学习 JavaScript'
},
{
text: '学习 Vue'
},
{
text: '整个牛项目'
}
]
}
})
</script>
在这里，也可以用 of 替代 in 作为分隔符，因为它是最接近 JavaScript 迭代器的语法
v-on(事件监听)示例
<div id="app-5">
<p>{{ message }}</p>
<button v-on:click="reverseMessage">逆转消息</button>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
var app5 = new Vue({
el: '#app-5',
data: {
message: 'Hello Vue.js!'
},
methods: {
reverseMessage: function() {
this.message = this.message.split('').reverse().join('')
}
}
})
</script>
v-model(双向绑定)示例
<div id="app-6">
<p>{{ message }}</p>
<input v-model="message">
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
var app6 = new Vue({
el: '#app-6',
data: {
message: 'Hello Vue!'
}
})
</script>
v-text/v-html使用示例
<div id="app">
<p>{{message}}</p>
<p v-text="message"></p>
<p v-html="message"></p>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
var app = new Vue({
el: '#app',
data: {
message: '<h1>Hello Vue!</h1>'
}
})
</script>
v-cloak使用
- 当不加v-cloak时候示例如下：
<div id="app">{{msg}}</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
alert("没有加v-cloak")
var app = new Vue({
el: '#app',
data: {
msg: "Hello"
}
})
</script>
出现结果如下
这种结果肯定是不可以的，所以就有了v-cloak
示例如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style type="text/css">
[v-cloak] {
display: none;
}
</style>
</head>
<body>
<div id="app" v-cloak>{{msg}}</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
alert("加了v-cloak")
var app = new Vue({
el: '#app',
data: {
msg: "Hello"
}
})
</script>
</body>
</html>
结果如下
这种结果才是正确的
