を反応させるためにjqueryのを追加し、私はJavascriptの世界に新たなんだとシンプルを作成するために、いくつかの開始は、私がReact Starter Kitで開始し、簡単なアップロードファイルであるwhch私の最初のモジュールを追加したプロジェクト 反応します。スターターキット
import React, { Component, PropTypes } from 'react';
import FormData from 'form-data';
import $ from 'jquery';
class UploadPanel extends Component {
state = {
file:'',
};
uploadSelectedFile() {
// Add the uploaded image content to the form data collection
var data = new FormData();
data.append("image", this.state.file);
data.append("temp", 'temp');
$.ajax({
method: "POST",
url: "rest/dicom/upload",
xhr: function() { // Custom XMLHttpRequest
var myXhr = $.ajaxSettings.xhr();
return myXhr;
},
cache: false,
data: data,
contentType: false,
processData: false,
success: function (data) {
alert('file sent');
console.log(data);
},
error: function (data) {
alert('error');
console.log(data);
}
});
}
handleFileChange(e){
let file = e.target.files;
if(file.length>0)
this.setState({file: file});
else
this.setState({file: ''});
}
render() {
//return <p> hi this is a test </p>
//var createItem = function (item) {
// return <li key={item.id}>{item.text}</li>;
//};
return <form onSubmit={this.uploadSelectedFile()}>
<input type="file" name="image" id="image" value={this.state.file} onChange={this.handleFileChange}/>
<input type="submit" value="ارسال" disabled={this.state.file!=''}/>
</form>;
}
}
export default UploadPanel;
しかし、私は、ページを開いたときに、(サーバーで)コンパイルには、次のエラーを与える:
TypeError: _jquery2.default.ajax is not a function

誰でも助けることができますか? なぜサーバー側でクライアントサイドコードを実行したいのですか?
