案例一 V-bind基本操作 通过这个案例了解基本的操作
<div id="app"> <img src="./img/1-1 (1).jpg" alt=""> <!--! 绑定图片利用V-bind指令 --> <img v-bind:src="imageSrc"> <img :src="imageSrc1"> <!-- !<img src="imageSrc2"> --> <!-- !绑定链接 --> <a v-bind:href="urlHref">语法的综合案例.html</a> <!--! 动态绑定元素 --> <!-- !给H2标签中增加style样式 --> <h2 :class="{active:isactive}" @click="change">{{msg}}</h2> <h2 :class="{active2:isactive}" @onmouseover="add">{{msgs}}</h2> <h2 :class="changeActive()" @click="change">{{msg}}</h2> <!--! onmouseout 鼠标移出时 鼠标 --> <!--! onmouseover 鼠标移入时 鼠标 --> <!--! V_bind绑定对象 --> <h1 :class="active2">{{bigname}}</h1> <h1 :class="a">{{bigname}}</h1> </div>
const app = Vue.createApp({ data: function () { return { imageSrc: './img/1-1 (1).jpg', imageSrc1: './img/1-1 (2).jpg', imageSrc2: './img/1-1 (3).jpg', urlHref: '语法的综合案例.html', msg: "我是动态的对象对所在的对象动态绑定事件", isactive: false, msgs: "我是动态的对象对所在的对象动态绑定事件", bigname:'V_bind绑定对象 ', active:'active', active2:'active2', } }, methods: { change() { this.isactive = !this.isactive }, changeActive() { return { active: !this.isactive } }, add(){ this.isactive2 = !this.isactive2 } } }) app.mount("#app") }
<script> function FistFunctionFmethod() { alert("开始学习Vue.js") FistFunctionFmethod() </script>
