Question

I’m using a hash table and I’m trying to check for object existence. However I haven’t been successful in figuring out how to do this. Could someone help guide me with this. Thanks.

current code.

When clientId equals field id and has item id return true, else add to saved_tokens.

var saved_tokens = {}; 

if ($.inArray(item.id, saved_tokens) == -1) { 
    saved_tokens.push[clientId] = item.id;
}

Answer 1

Don’t use jQuery for that. Use pure JavaScript:

if (!saved_tokens.hasOwnProperty(clientId)) { // If clientId is not in the hash
    saved_tokens[clientId] = item.id;
}

.push is an array method. A {} creates an object. Since this object is not an array, it doesn’t have any array methods.
