jquery - Automatically update JavaScript object property when another object's property is set -


i have array of objects, each containing property named title.
title property can hold 1 of 2 possible string values - "main" or "local". single element in array can have "main" title value @ given time, , rest of elements should have title property set "local".

for instance, take following array:

var locations = [   {     title:"main",     place:"uk"   }, {     title:"local",     place:"usa"   }, {     title:"local",     place:"russia"   } ]

when setting place:"usa" object's title property "main", want place:"uk" object's title property automatically set "local".

how achieve javascript?

one way set title values local, before setting desired object main. way remember index set main , revert local when main changed.
