1.基础事件，先弹框试试
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title></title> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <style> </style> <script src="vue.js"></script> <script> window.onload=function(){ new Vue({ el:'#box', data:{ //数据 arr:['apple','banana','orange','pear'], json:{a:'apple',b:'banana',c:'orange'} }, methods:{ show:function(){ alert(1); } } }); }; </script> </head> <body> <div id="box"> <input type="button" value="按钮" v-on:click="show()"> </div> </body> </html>
描述：
使用v-on:事件名="方法名"，在methods定义方法
结果：
2.向数组中添加一项
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title></title> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <style> </style> <script src="vue.js"></script> <script> window.onload=function(){ new Vue({ el:'#box', data:{ //数据 arr:['apple','banana','orange','pear'], json:{a:'apple',b:'banana',c:'orange'} }, methods:{ add:function(){ this.arr.push('tomato'); } } }); }; </script> </head> <body> <div id="box"> <input type="button" value="按钮" v-on:click="add()"> <br> <ul> <li v-for="value in arr"> {{value}} </li> </ul> </div> </body> </html>
结果：
点击完按钮后：
点击完后数组多出一项
