问题描述
我正在使用 Parse.com 构建一个 JavaScript 应用程序，我需要上传照片.我有一个表单，允许用户在他们的文件系统上选择图像，但接下来我该怎么做?我在 Parse 站点上找不到任何相关文档(无论如何都不是 JavaScript SDK).
I'm using Parse.com to build a JavaScript app, and I need to upload photos. I have a form which allows users to select the image on their filesystem, but what do I do with it next? I can't find any documentation for this on the Parse site (not for the JavaScript SDK, anyway).

$(document).ready(function() {
// ***************************************************

Parse.initialize("YOUR_APPLICATION_ID", "YOUR_CLIENT_ID");
function saveJobApp(objParseFile)
{
var jobApplication = new Parse.Object("JobApplication");
jobApplication.set("applicantName", "Joe Smith");
jobApplication.set("profileImg", objParseFile);
jobApplication.save(null,
{
success: function(gameScore) {
// Execute any logic that should take place after the object is saved.
var photo = gameScore.get("profileImg");
$("#profileImg")[0].src = photo.url();
},
error: function(gameScore, error) {
// Execute any logic that should take place if the save fails.
// error is a Parse.Error with an error code and description.
alert('Failed to create new object, with error code: ' + error.description);
}
});
}
$('#profilePhotoFileUpload').bind("change", function(e) {
var fileUploadControl = $("#profilePhotoFileUpload")[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);
parseFile.save().then
(
function()
{
saveJobApp(parseFile);
},
function(error)
{
alert("error");
}
