I am looking for an alternative to using an object/variable in global scope — I would like to associate key/value pairs with specific DOM elements (eg, a DIV), so that I can use them as input for logic that processes other elements (eg, child elements of said DIV).
I tried something naive like: $(‘[foo=bar]’).key=’value’ , and $(‘[foo=bar]’)[key]=’value’, but it puked.
Doing something like: var foobar = $(‘[foo=bar]’); foobar.key = ‘value’ — works, but the new property/value only affects the new object (ie, foobar, not $(‘[foo=bar]’))
Most likely there’s something terribly basic I am overlooking. Any help is appreciated, thanks!
$().data()is what you seek
