带有键/值的Javascript测试哈希表

Question

I have a saved_tokens hashtable. I also have the key and the value. I would like to check the hashtable to see if the pair exist, if exist, do something. Thanks.

Code thus far

var saved_tokens = {}

//method
    _suggest: function( items, clientId ) {

        var filteredItems = [];

        $.each(items, function(i, item ) {
            if(saved_tokens.hasOwnProperty(clientId)) { 

                //need to test for item here
                if(item exist need help) {
                    filteredItems.push(item);
                }
            }
        }); 
   }

I am not really sure what you what, but I assume that you are trying to get the filteredItems list based on the matched items b/w items list + clientID and saved_tokens .

Try,

_suggest: function( items, clientId ) {

        var filteredItems = [];

        $.each(items, function(i, item ) {
            if(saved_tokens.hasOwnProperty(clientId) &&
                         saved_tokens[clientID] === item) {
                    filteredItems.push(item);

                    //add a return false here to terminate the loop.
                }
            }
        }); 
   }
