Although the code works as expected it throws
"An error occurred whilst trying to contact the server: 200 parsererror SyntaxError: Unexpected end of JSON input"
The success branch is never called but the data arrives to the api.
Should I be concerned and solve it or it probably won't cause problems elswhere? Thank you for your help.
<script>
$(document).ready(function () {
$("#Save").click(function () {
var data2send = JSON.stringify("test");
$.ajax({
url: 'https://localhost:44348/api/products/PostProduct',
type: 'POST',
data: data2send,
contentType: 'application/json',
dataType: 'json',
success: function (data2send) {
console.log(data2send);
},
error: function (jQXHR, textStatus, errorThrown) {
console.log("An error occurred whilst trying to contact the server: " + jQXHR.status + " " + textStatus + " " + errorThrown);
console.log(data2send);
}
});
});
});
</script>
Controller
[HttpPost]
[Route("PostProduct")]
public void Post([FromBody] string obj)
{
Product.prod.Add(new Product() { ProductId = 12, ProductName = obj, Price = 12 });
}
I have a problem with Ajax call. I get this error in console:
SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data.
What is the reason of this error?
My code is:
function _save(action) {
var dataObj = {
"offer_id": offer_id,
"user_id": user_id
};
$.ajax({
url: Base_URL + "/offers/" + action + "/",
type: "POST",
data: dataObj,
success: function (data) {
//console.log(data);
var obj = JSON && JSON.parse(data) || $.parseJSON(data);
if(obj.action === 'success') {
MessageBoxOK("<?php echo __('Saved successfully'); ?>");
window.location.href = Base_URL + 'offers/view/' + obj.offer_id;
} else {
MessageBoxError("<?php echo __('Error'); ?>");
}
},
error: function (data) {
MessageBoxError("<?php echo __('Error'); ?>");
}
});
}
In my controller I have:
<?php
$offer = Model_Offers::updateOffer($_POST['offer_id'], $offerArr);
$view = json_encode(array('action'=>'success', `offer_id`=>$_POST['offer_id']), JSON_FORCE_OBJECT);
I have wasted my day finding solution for this.
This is my jquery function
And this is the error I get "Uncaught SyntaxError: Unexpected token <"
Please Help
Thanks
$('#post_comment').click(function(){

});
in your ajax you forgot to close a class with ==> '
$('#post_comment').click(function(){
var question_id=$('#question_id').val();
var comment=$('#comment').val();
var user_id=$('#user_id').val();
$.ajax({
type : 'POST',
url : 'questions/update_question',
data : {question_id:question_id,comment:comment,user_id:user_id},
success:function(response) {
$('#comment_textarea').toggleClass("hidden");
// alert(response);
var result=JSON.parse(response);
var div1="<div class='row comment_rows>";
// you forget to close the class -----^
var div2="<div class='col-sm-9 comment_description_column'></div>";
var div3="<div class='col-sm-3 comment_description_userinfo'></div></div>";
$('.comment_rows:last').append(div1,div2,div3);
$('.comment_description_column:last').text(result.comment_description);
$('.comment_description_userinfo:last').text(result.user_id);
},
error: function (xhr, ajaxOptions, thrownError) {
console.log("Status: " + xhr.status);
console.log("Message: " + thrownError);
}
});
});
I would like to know why could you get this error:
Error code: 102, error message: $in requires an array
I'm using Parse JavaScript SDK.
The data structure it this one:
The source code of the function is this one:
Parse.Cloud.define(
"unfollow",
function(request, response) {
var currentUserID = request.params.currentuser;
var followedUserID = new Array(request.params.followeduser);
var queryRemoveFollower = new Parse.Query("userRelation");
queryRemoveFollower.containedIn("userObjectId", followedUserID);
queryRemoveFollower.find({
success: function(result) {
for(var i=0; i<result.length; i++) {
result[i].remove("followers", currentUserID);
result[i].save();
}
var stopFollowingQuery = new Parse.Query("userRelation");
stopFollowingQuery.equalTo("userObjectId", currentUserID);
stopFollowingQuery.find({
success: function(result) {
for(var i=0; i<result.length; i++) {
result[i].remove("following", followedUserID);
result[i].save();
}
response.success("Unfollow succesful!");
},
error: function(error) {
response.success("Something went wrong. Error code: " + error.code + ", error message: " + error.message);
}
});
},
error: function(error) {
response.success("Something went wrong. Error code: " + error.code + ", error message: " + error.message);
}
});
}
);
I know that the data is being currently sent:
fn_unfollow.parse_data_user_id = ruWNYycty7
fn_unfollow.idOfTheUserToUnfollow = KcCNa39sgk
Thanks in advance for the help!!
The problem in your code is the line:
var followedUserID = new Array(request.params.followeduser);
JavaScript's Array constructor has two possible constructors:
new Array(element0, element1, ..., elementN)
new Array(arrayLength)
Since request.params.followeduser is an integer, folowedUserID is being initalized as a EMPTY array with length of request.params.followeduser.
The fix is to use either of the following (untested...):
var followedUserID = new Array(1, request.params.followedUser);
or (preferred):
var followedUserId = [request.params.followedUser];
I've got the follwing parse.com cloud code
Parse.Cloud.afterSave("Action", function (request) {
var BookStatus = Parse.Object.extend("BookStatus");
var Book = Parse.Object.extend("Book");
var book = new Book();
var actionType = request.object.get("actionTypePointer").id;
var bookId = request.object.get("bookPointer").id;
var queryBook = new Parse.Query("Book");
var newBookStatus;
queryBook.get(bookId,{
success: function (gottenBook) {
newBookStatus = "idOfTheBookStatus";
book.id = bookId;
book.set("bookStatus", new BookStatus({id: newBookStatus}));
gottenBook.set("bookStatus", new BookStatus({id: newBookStatus}));
//OPTION 1
gottenBook.save(null,{
success: function(data) {
console.log("Bookstatus updated1");
},
error: function (data,error) {
// error is a Parse.Error with an error code and description.
console.log("Error: " + error.code + " " + error.message);
}
});
//OPTION 2
book.save(null,{
success: function(data) {
console.log("Bookstatus updated2");
},
error: function (data,error) {
// error is a Parse.Error with an error code and description.
console.log("Error: " + error.code + " " + error.message);
}
});
},
error: function (object, error) {
// The object was not retrieved successfully.
// error is a Parse.Error with an error code and description.
console.log("Error: " + error.code + " " + error.message);
}
});
OPTION1
I try to save the queried book after setting the bookStatus to the returned book.
OPTION2
I try to save the new book object after setting the book.Id
book.id = bookId;
book.set("bookStatus", new BookStatus({id: newBookStatus}));
However with any of the 2 options I end up getting in the parse.com logs:
Error: 101 object not found for update
Error: 101 object not found for update
Any idea of what I am doing wrong?
Thanks in advance!
--EDIT
New implementation with fetch:
Parse.Cloud.afterSave("Action", function (request) {
var BookStatus = Parse.Object.extend("BookStatus");
var Book = Parse.Object.extend("Book");
var book = new Book();
var actionType = request.object.get("actionTypePointer").id;
var bookId = request.object.get("bookPointer").id;
book.id = bookId;
console.log("before fetch book.id" + book.id);
var newBookStatus;
book.fetch({
success: function (book) {
newBookStatus = "XMFkXS9NVv";
book.set("bookStatus", new BookStatus({id: newBookStatus}));
console.log("book" + book);
console.log("book.id" + book.id);
console.log("book.isValid()" + book.isValid());
book.save(null,{
success: function(data) {
console.log("Book Status updated to:" +newBookStatus);
},
error: function (data,error) {
// error is a Parse.Error with an error code and description.
console.log("Error: " + error.code + " " + error.message);
}
});
},
error: function (object, error) {
// The object was not retrieved successfully.
// error is a Parse.Error with an error code and description.
console.log("Error: " + error.code + " " + error.message);
}
});
});
With result:

Your afterSave hook is overwriting the fetched Book's object id. Even if you're setting the same object id on it, the object now thinks it's dirty and it's no longer a valid reference.
Avoid this by using the book returned by get() and not updating it's id:
Parse.Cloud.afterSave("Action", function (request) {
var BookStatus = Parse.Object.extend("BookStatus");
var Book = Parse.Object.extend("Book");
var book = new Book();
var actionType = request.object.get("actionTypePointer").id;
var bookId = request.object.get("bookPointer").id;
var queryBook = new Parse.Query("Book");
var newBookStatus;
queryBook.get(bookId,{
success: function (book) {
newBookStatus = "idOfTheBookStatus";
book.set("bookStatus", new BookStatus({id: newBookStatus}));
book.save(null,{
success: function(data) {
console.log("Bookstatus updated1");
},
error: function (data,error) {
// error is a Parse.Error with an error code and description.
console.log("Error: " + error.code + " " + error.message);
}
});
},
error: function (object, error) {
// The object was not retrieved successfully.
// error is a Parse.Error with an error code and description.
console.log("Error: " + error.code + " " + error.message);
}
});
});
Since you already know the id for this book, instead of using a query, you can create a pointer and fetch it directly.
Final afterSave hook:
Parse.Cloud.afterSave("Action", function (request) {
var BookStatus = Parse.Object.extend("BookStatus");
var Book = Parse.Object.extend("Book");
var book = new Book();
var actionType = request.object.get("actionTypePointer").id;
var bookId = request.object.get("bookPointer").id;
book.id = bookId;
var newBookStatus;
book.fetch({
success: function (book) {
newBookStatus = "idOfTheBookStatus";
book.set("bookStatus", new BookStatus({id: newBookStatus}));
book.save(null,{
success: function(data) {
console.log("Bookstatus updated1");
},
error: function (data,error) {
// error is a Parse.Error with an error code and description.
console.log("Error: " + error.code + " " + error.message);
}
});
},
error: function (object, error) {
// The object was not retrieved successfully.
// error is a Parse.Error with an error code and description.
console.log("Error: " + error.code + " " + error.message);
}
});
});
Here's how I did it after some running around
ParseCrashReporting.enable(this);
// Enable Local Datastore.
Parse.enableLocalDatastore(this);
// Add your initialization code here
Parse.initialize(this, "*******", "******");
ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();
ParseACL.setDefaultACL(defaultACL, true);
// save the installation
ParseInstallation.getCurrentInstallation().saveInBackground();

Whilst looking for this error I found this thread the most useful. I wanted to add that object not found for get can also essentially mean foreign key reference not found.
The not found for get error can be incredibly unhelpful; for me it wasn't even giving a line number where the error was occurring, the error message is very vague and I could not find reference to the phrase in any of the documentation.
If you are getting this error, you will find a lot of reference to permissions issues, but if you are already using the master key then you need to find the object that is being referenced by a foreign key on your selected object.
