[英]How do I upload an image using the Parse.com JavaScript SDK?
我正在使用Parse.com構建一個JavaScript應用程序,我需要上傳照片。 我有一個表單,允許用戶在他們的文件系統上選擇圖像,但我接下來該怎么辦呢? 我在Parse站點上找不到任何相關文檔(無論如何都不適用於JavaScript SDK)。
這是一個關於如何上傳圖像的簡單示例:
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<script type="text/javascript" src="http://www.parsecdn.com/js/parse-1.2.15.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
// ***************************************************
// NOTE: Replace the following your own keys
// ***************************************************
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");
}
);
});
});
</script>
<body>
<input type="file" id="profilePhotoFileUpload">
<img id="profileImg"/>
</body>
