目前，当用户选择一个文件时，它会直接上传到 Parse。我现在添加了一对输入文本字段，例如个人姓名、地址，只有当用户单击选择按钮时，我才会同时将其记录到 Parse 中，一旦用户选择了文件，它就会自动提交.

function saveDocumentUpload(objParseFile) {

documentUpload.set("Name", "");
documentUpload.set("DocumentName", objParseFile);
documentUpload.save(null, {
success: function(uploadResult) {
// Execute any logic that should take place after the object is saved.
var photo = uploadResult.get("profileImg");
$("#profileImg")[0].src = photo.url();
},
error: function(uploadResult, error) {
// Execute any logic that should take place if the save fails.

最佳答案
您有两次“documentFileUpload”:
变化:
<form>
<input type="file" id="documentFileUpload">
<br />
<input type="text" value ="UserID"><br />
<input type="text" value ="Address"> <br />
<input type="submit" id="documentFileUpload" value="submit">
</form>
收件人:
<form>
<input type="file" id="documentFileUpload">
<br />
<input type="text" value ="UserID"><br />
<input type="text" value ="Address"> <br />
<input type="submit" id="documentFileUploadButton" value="submit">
</form>
编辑
要回答您关于记录 UserId 和 Address 字段的评论，请参阅以下代码。我更改了文件上传绑定(bind)到按钮并绑定(bind)了点击事件。这将修复您选择的文件上传问题。
此外，添加了 id 的 user_id 和地址以允许 jQuery 从这些字段中获取值:
$('#documentFileUploadButton').bind("click", function (e) {
var fileUploadControl = $("#documentFileUpload")[0];
var file = fileUploadControl.files[0];
var name = file.name; //This does *NOT* need to be a unique name
var parseFile = new Parse.File(name, file);
var user_id = $('#user_id').val();
var address = $('#address').val();
parseFile.set('UserId', user_id);
parseFile.set('Address', address);
parseFile.save().then(
function () {
saveDocumentUpload(parseFile);
},
function (error) {
alert("error");
}
);
});
然后:
<form>
<input type="file" id="documentFileUpload">
<br/>
<input type="text" value="UserID" id="user_id">
<br/>
<input type="text" value="Address" id="address">
<br/>
<input type="submit" id="documentFileUploadButton" value="submit">
</form>
