这个想法很简单:Vue 实例从 API 加载组。这些组使用 v-for 语法显示。
groupdata 格式正确,并使用 .push 函数添加到 app.groups 中,这应该会更新 v-for 列表。
但是,v-for 列表不会更新。
当我将 v-for="group in groups" (从外部加载)更改为 v-for="group in people" (已经在应用程序中)时,它确实提供了输出。
HTML
<div id="app" class="col-md-8 col-md-offset-2">
<div class="panel panel-default">
<div class="panel-heading">Realtime Socket Chat</div>
<div class="panel-body" v-if="dataReady" v-for="group in groups"> @{{ group.name }}
<a v-bind:href="group.link" class="pull-right">
<div class="btn btn-xs btn-primary">
Join
</div>
</a>
</div>
</div>
</div>
</div>
Vue
var app = new Vue({
el: "#app",
data: {
groups: [],
people: [{name: 'hi'}, {name: 'lol'}]
},
mounted: function() {
this.load()
},
methods: {
load: function() {
axios.get('http://example.com/groups')
.then(function (response) {
console.log(response.data.groups);
response.data.groups.forEach(function(group) {
app.groups.push(group);
});
// app.groups.forEach(function (group) {
// group.link = '/g/' + group.id + '/join';
// });
// console.log(response.data.groups);
console.log(this.groups); //outputs [{...}, {...}] so this.groups is good
})
.catch(function (error) {
this.errors.push(error);
console.log(error);
})
}
}
});
