Check if a Javascript Object has a property name that starts with a specific string -

lets have javascript objects one:

addr:housenumber: "7" addr:street: "frauenplan" owner: "knaut, kaufmann"

how can check if object has property name starts addr? i’d imagine along lines of following should possible:

if (e.data[addr*].length) {

i tried regexp , .match() no avail.

you can check against object's keys using array.some returns bool.

if(object.keys(obj).some(function(k){ return ~k.indexof("addr") })){    // has addr property }

you use array.filter , check it's length. array.some more apt here.
