一 点睛
通过定义组件就可以通过组件名组件标签进行组件模板复用。
二 代码
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<div id="app">
<button v-on:click="count++">我被点击了 {{count}} 次</button>
<counter></counter>
<counter></counter>
<counter></counter>
<counter></counter>
<counter></counter>
<button-counter></button-counter>
</div>
<script src="../node_modules/vue/dist/vue.js"></script>
<script>
//1、全局声明注册一个组件
Vue.component("counter", {
template: `<button v-on:click="count++">我被点击了 {{count}} 次</button>`,
data() {
return {
count: 1
}
}
});
//2、局部声明一个组件
const buttonCounter = {
template: `<button v-on:click="count++">我被点击了 {{count}} 次~~~</button>`,
data() {
return {
count: 1
}
}
};
new Vue({
el: "#app",
data: {
count: 1
},
components: {
'button-counter': buttonCounter
}
})
</script>
</body>
</html>
