YUI Library Examples: YAHOO Global Object: Combining Simple Data Sets with `YAHOO.lang.merge`

YAHOO.lang is packaged with the YAHOO Global Object

YAHOO.lang comes bundled with the YAHOO Global Object.


1	<script type="text/javascript" src="http://yui.yahooapis.com/2.9.0/build/yahoo/yahoo-min.js"></script>
	view plain \| print \| ?

If you are using any other YUI component on your page, you should already have YAHOO.lang available.

Merging hash tables

In the example illustrated above, we merge three object literals in the form of hash tables. Note the key values in later parameters override those in previous parameters.


1	YAHOO.namespace('example');
2
3	YAHOO.example.set1 = { foo : "foo" };
4	YAHOO.example.set2 = { foo : "BAR", bar : "bar" };
5	YAHOO.example.set3 = { foo : "FOO", baz : "BAZ" };
6
7	YAHOO.example.doMerge = function () {
8	var Ye = YAHOO.example;
9
10	var merged = YAHOO.lang.merge(Ye.set1, Ye.set2, Ye.set3);
11
12	// Output the stringified version of merged
13	var result = YAHOO.util.Dom.get('demo_result');
14	result.innerHTML = YAHOO.example.stringifyObj(merged);
15	}
16
17	YAHOO.util.Event.on('demo_btn','click',YAHOO.example.doMerge);
	view plain \| print \| ?
