将var附加到FormData [英] Append var to FormData

问题描述

我正在使用CKEditor作为所构建的内部电子邮件系统的WYSIWYG编辑器，这需要我从textarea输入中获取数据，如下所示:

I am using CKEditor as a WYSIWYG editor for an internal email system that I'm building, which requires me to get the data from from the textarea input like this:

var message = CKEDITOR.instances.messageArea.getData();

我还允许用户发送附件，并通过HTML5 FormData将文件发送到服务器.

I am also allowing users to send attachments and I am sending the files to the server via the HTML5 FormData.

//create form variable
var form = $('#sendIndividualEmail')[0];
var formData = new FormData(form);

我尝试将message变量追加到formData，但是formData似乎只允许将表单字段追加.

I have tried to append the the message variable to the formData, but it seems that formData only allows form fields to be appended.

如果不是表单字段，是否有其他方法可以将var附加到FormData?如果没有，是否还有另一种方法可以使用formData将消息变量获取到服务器?

Is there alternative way to append a var to FormData if it isn't a form field? If not, is there another way to get the message variable to the server with the formData?

ajax代码:

request = $.ajax({
            url: baseURL+'/sendIndividualMessage',
            type: "post",
            data: formData,
            mimeType: "multipart/form-data",
            dataType: json,
            contentType: false, //required for formData
            cache: false,
            processData: false, //require for formData
        });

推荐答案

您可以像这样将数据附加到FormData上:

You can append data to a FormData like that :

formData.append('message', message);

它不必是一个表单字段. 要调试FormData，您必须发布数据.

It doesn't need to be a form field. To debug FormData, you have to post the data.

MDN FormData.append()参考

在这里看看: FormData.append("key"，"value" ;)无法正常工作
