rated 0 times [ 84] [ 3] / answers: 1 / hits: 14266 / 11 Years ago, thu, january 2, 2014, 12:00:00

I'm trying to create a Dictionary with a key and a value list pair. I'm able to create a dictionary for a key value pair but I need to insert a list of Items as value for a key value.
Here is my approach:

keys = ['A', 'B', 'C'];

Elements Corresponding to 'A' : 'apple'

Elements Corresponding to 'B' : 'ball', 'balloon','bear'

Elements Corresponding to 'C' : 'cat','cow'

and my result should be like:

{ key:'A' value:['apple'], key:'B' value:['ball',balloon','bear'], Key:C' value:['cat','cow']}

Here is just a sample data, I will get data dynamically from a table.Please help me out.Thanks In advance.

This code can add a new key-value pair into some dictonary like object.

var dictionary= {};

function insertIntoDic(key, value) {

 // If key is not initialized or some bad structure

 if (!dictionary[key] || !(dictionary[key] instanceof Array)) {

    dictionary[key] = [];

 }

 // All arguments, exept first push as valuses to the dictonary

 dictionary[key] = dictionary[key].concat(Array.prototype.slice.call(arguments, 1));

 return dictionary;

}
