19             <button class="btn1" v-on:click="blow" v-bind:class="{disabled: ended}" >使劲敲</button>
20             <button v-on:click="restart">重新开始</button>
21         </div>
22     </div>
23     <script src="vueJson.js"></script>
24 </body>

html
总结:
v-bind:class的后边,是一个对象,返回布尔值!!!
并且,绑定的class样式名,不能有中横线链接符,比如:img-brust,这种会导致vue解析错误

 css:

 1 /*京东初始化*/
 2 * {
 3     margin: 0;
 4     padding: 0;
 5     font-family: "微软雅黑"
 6 }
 7 em,i {
 8     font-style: normal

15     vertical-align: middle
16 }
17 button {
18     cursor: pointer
19 }
20 a {

22     text-decoration: none
23 }
24 a:hover {
25     color: #c81623
26 }
27 div{

34     margin: 0 auto;
35     background: url("img/bag.png") no-repeat;
36 }
37 .imgburst{
38     background: url("img/bag-burst.png") no-repeat;
39 }
40 .progress{
41     width: 200px;
42     height: 20px;
43     margin: 0 auto;
44     overflow: hidden;
45     background: #fff;
46     border-radius: 5px;
47     border: 2px solid red;

61     margin-left: 10px;
62     border-radius: 5px;
63     border: 1px solid #999;
64     background: #e5ffc9;
65 }
66 button:hover,button:focus{
67     outline: none;}
68 button:hover{

70     border-color: #4488ff;
71     color: #fff;
72 }
73 .btn1:hover{
74     background: red;
75     border-color: red;
76 }
77 button.disabled{
78     cursor: not-allowed;
79     background: #999
80 }
css

Vue.js:

 1 new Vue({
 2     el: "#app",
 3     data: {
 4         health: 100,
 5         ended: false
 6     },
 7     methods: {
 8         blow: function(){
 9             this.health -= 10;
10             if(this.health <= 0){
11                 this.ended = true;
12                 this.health = 0
13             }
14             // console.log(this.health,this.ended)
15         },
16         restart: function(){
17             this.health = 100;
18             this.ended = false;
19             // console.log(this.health,this.ended)
20         }
21     }
22 })
Vue实例
注意:
console.log打印很有帮助

  

二、v-on鼠标移动事件 —— 时刻显示鼠标地理位置

 html:

1 <div id="canvas" @mousemove="mouseMove">x: {{mouseX}}, y: {{mouseY}}
2                         <em class="em" @mousemove.stop="">在我的区域内停止更新,都是阻止事件(冒泡)修饰符的功劳</em>
3                     </div>
html Code

css:

 1 #canvas{
 2     width: 680px;
 3     padding: 150px 0;
 4     text-align: center;
 5     background: #dedede;
 6 }
 7 .em{
 8     display: block;
 9     padding: 10px 5px;
10         background: #f5c9c9;
11     font-style: normal;
12     color: #333;
13 }
css

Vue.js

 1 new Vue({
 2     el: "#vue-app",
 3     data: {
 4         mouseX: 0,
 5         mouseY: 0,
 6     },
 7     methods:{
 8         mouseMove: function(event){
 9             console.log("5、我是mouseMove函数");
10             // console.log(event);
11             this.mouseX = event.offsetX;
12             this.mouseY = event.offsetY;
13         }
14     }
15 })
Vue.js
注意:
console.log把event事件输出后,寻找到offsetX和Y属性的
