废话不多说，直接上代码

<ul v-for="info in myInfo">
<input type="text" v-model="info.city" disabled readonly>
<input type="text" v-model="info.name" disabled readonly>
</ul>
</div>
<script>
new Vue({
el: '#app',
data: {
title: '测试动态添加',
city: '',
name: '',
info: '',
myInfo: []
},
mounted: function () {
this.getInfo();
},
methods: {
getInfo(){
this.info='[{"city":"curry","name":"我是盐城人"}]';
this.myInfo=JSON.parse(this.info);
},
handleClick() {
var str = {
city: this.city,
name: this.name
};
this.myInfo.push(str);
this.city = "";
this.name = "";
var str = JSON.stringify(this.myInfo);
console.log(str);
}
}
})
</script>
</body>
</html>
代码里还包含了获取数据转JSON对象和JSON对象转字符串打印出来的动作。
