Question

Can someone please redirect me to the right link or give an example of how to work with two dimensional array or HashTable in JQuery? I tried google but did not get the answer. I want to avoid using any plugins. All i want to do it, store some information and retrieve them like HashTable way.

Answer 1

Depending on what you want to use as keys into your “hashtable”, you might want to use an object with array properties instead of a two dimensional array.

For instance:

var hashtable = {};
hashtable['screaming'] = ["red","orange"];
hashtable['mellow'] = ["skyblue","yellow","green"];

you can also set and access values in an object using dot notation:

hashtable.screaming = ["red","orange"];
alert(hashtable.screaming[0]);

If you’re just looking to keep track of key/value pairs then an object is the way to go:

var hashtable = {};
hashtable['key1'] = 'value1';
hashtable['key2'] = 'value2';
hashtable.key3 = 'value3';
