【问题描述】:
请查看我的代码,我不确定我做错了什么? 我想在 id="select1" 发生变化时获取新的 JSON 数据,然后将参数发送到 id="select2" 然后 id="select2" 将在选项中显示数据。
var appZone = new Vue({
el: '#el',
data() {
return {
options: [],
list:[],
selected:''
}
},
mounted() {
var self = this
axios.get('/wp-json/tour-api/v1/search/0')
.then(function (response) {
console.log(response);
self.options = response.data;
})
.catch(function (error) {
console.log(error);
});
},
methods: {
onChange: function (){
axios.get('/wp-json/tour-api/v1/search/'+this.selected)
.then(function (response) {
//console.log(response);
self.list = response.data;
console.log(list)
})
.catch(function (error) {
console.log(error);
});
}
}
})
<script src="https://unpkg.com/vue"></script>
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<div id="el">
<select id="select1" v-model="selected" class="custom-select" v-on:change="onChange" >
<option v-for="item in options" v-bind:value="item.id" >
{{ item.title }}
</option>
</select>
<span>Selected: {{ selected }}</span>
<select id="select2" class="custom-select" >
<option v-for="data in list" v-bind:value="data.country_id">{{ data.title }}</option>
</select>
</div>
【问题讨论】:
-
你需要在onChange函数中添加var self = this。

你又帮我了。谢谢
