Set an IF on a POST depending on the # of objects already there? Get JSON Array length?
I'm currently creating new objects (stores) for users from a bank of global stores.
This is working, however I want to limit this to only 3 stores per user.
So I'm assuming, (open to suggestions) what I want to do here is do an if statement to check to see if the JSON results already have 3 objects. I'm not sure how to get that JSON data's array length?
I just stuck the jsonGoesHere.length in there as a placeholder which obviously does not work.
I appreciate any ideas how to do this?
$(document).on('click', '#availableStr', function(e){
e.preventDefault();
var newStore = {
name: this.name,
sort: 'list',
userID: userId,
};
if(jsonGoesHere.length >= 3){
alert('You already have too many stores');
} else {
$.ajax({
type: 'POST',
url: '/stores/user/' + userId,
data: newStore,
success: function(newStore) {
alert(`${newStore.name} Added!`);
console.log(newStore);
location.reload();
}
});
}
});
