I have this array which when there is only one item left in the array, causes the array to be set to undefined.
Basically, this:
var array = {"example"}
To do this I say this:
if (array[1] == NULL){
compiled = undefined;
}
info.add('assignment', compiled);
info.save(null, {
success:function(){//Whatever};
The problem is that parse does not update the object with the value undefined.
Any help?
I faced the problem and made the research, here to share.
The problem is that parse does not update the object with the value undefined.
Using unset() can clear the property of parse object, and then use save() to update property.
Here is the document : Parse Object
In your use case, would be like ...
let array = ["example"]
if (array[1] == NULL) {
info.unset('assignment'); //set assignment to undefined
}
else {
//Other way to set assignment property
}
info.save(null, { success: function() { //Whatever };
Hope this will help.
Try this:
Change this if statement:
if (array[1] == NULL){
compiled = undefined;
}
TO this:
if(array.length > 1){
compiled = undefined;
}
I have figured out the answer to my own question.
Basically, Parse has a function to unset an array to undefined.
I unset the parse array, then save it,
If my local array is not null, then I update the local array to the parse array.
I will provide code if anyone needs help!
