如何使用$ .ajax（）输入字段文本和文件上传？

本文介绍了如何使用$ .ajax（）输入字段文本和文件上传？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

这是我的代码

$.ajax({ type: 'post', url: '../lib/upload.php', data: new FormData( $("#niceidentifier") ), processData: false, contentType: false, success: function (response) { if(response == 'success') { return true; } else { alert(response); console.log(response); } } });

HTML表单只是基本的HTML（包括enctype和method post），但不幸的是没有数据被传递。如何上传文件并传递一次输入数据？

The HTML form is just basic HTML (enctype included and method post) but unfortunately NO data is passed. How can I upload a file AND pass the input data once?

推荐答案

您可以使用 FormData 通过文件。和processData，contentType设置为false强制。因为你不打算在客户端处理文件。

You can use FormData to pass the File. and processData,contentType set to false compulsory. because you are not going to process file in client side.

// Create a formdata object and add the files var data = new FormData(); $.each(files, function(key, value) { data.append('myFile', value); //No I18N }); $.ajax({ url: '/your-url', type: 'POST', data: data, cache: false, dataType: 'json', //No I18N processData: false, // Don't process the files contentType: false, // Set content type to false as jQuery will tell the server its a query string request success: function(data, textStatus, jqXHR) { // do something }, error: function(jqXHR, textStatus, errorThrown) { // Handle errors here } });

或者您可以使用以下数据发送文件：

$( '#formId' ) .submit( function( e ) { e.preventDefault(); $.ajax({ url: '/your-url', type: 'POST', data: new FormData( this ), cache: false, dataType: 'json', //No I18N processData: false, // Don't process the files contentType: false, // Set content type to false as jQuery will tell the server its a query string request success: function(data, textStatus, jqXHR) { // do something }, error: function(jqXHR, textStatus, errorThrown) { // Handle errors here } }); });
