嘿,我是新手,我的要求是,当用户单击按钮时,将向服务器触发 ajax get 请求,并且根据收到的响应,我必须准备 html 并显示它。下面是我的代码它不起作用..它可以通过使用在jquery中解决,async: false
但我不必使用任何想法如何使用axios解决
import React from "react";
import axios from "axios"
class UserItems extends React.Component {
constructor(props) {
super(props);
this.state = {
useritem: ''
}
}
prepareHtmlOnAjaxResponse(){
var user_item = this.state.useritem
// html prepation done here
return preparedHtml;
}
getDatFromServeronclick() {
// getting user data from server is done in this function
// when data is receieved it is stored in a state
var self = this;
var promise = axios.get("http://localhost:4000/user/1/items.json")
promise.then(function (response) {
self.setState({ useritem: response.data.items })
self.prepareHtmlOnAjaxResponse() // prepare html
})
console.log("executing first and returning null")
}
render() {
var result = this.getDatFromServeronclick() // getting undefined value this has to be called onclick
return (
<div>
{result} / result is undefined
</div>
);
}
}
export default UserItems;
