YAHOO Global Object: Combining Simple Data Sets with YAHOO.lang.merge

YAHOO.lang.merge allows you to combine any number of input objects and output a single merged set.

Click the Merge button to generate the merged set.

set1 = { foo : "foo" };
set2 = { foo : "BAR", bar : "bar"  };
set3 = { foo : "FOO", baz : "BAZ" };

result

click Merge

YAHOO.lang is packaged with the YAHOO Global Object

YAHOO.lang comes bundled with the YAHOO Global Object.

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.
