vue2: Cannot read property 'xxxx' of undefined

<temlate>
{{aaa.xxx}}
</template>

///////////////////// 实际代码 //////////////////////////////

data() {

return() {
    aaa: null
}

},
methods: {

var self = this;
$.get('www.com', function(res){
    self.aaa = res.data;
})

}

/**
ajax res 结构:

res: {

xxx: 111,
yyy: 222,
zzz: 333

}

**/

按照如上代码写的话就会出现 Cannot read property 'xxxx' of undefined
vue 1.0 是不会出现这样的错误的。

之前做一个demo的时候也有遇到过,我猜是Vue-resource的api改了,可以上他的github看看

`{
  // GET /someUrl
  this.$http.get('/someUrl').then(response => {
 // get body data
  this.someData = response.body;
  }, response => {
  // error callback
  });
}`

希望能帮助你把,我入门也不久...
