Use Array.prototype.map() to map one array to another array based on a mapping function:

var metaArr = [{"meta_value":"Germany"},{"meta_value":"United States"}];
var arrayOfStates = metaArr.map(function(item){return item.meta_value});

Simply use arrayOfStates as your source for the autocompletion.

You can use map

var res = [{"meta_value":"Germany"},{"meta_value":"United States"}].map(function (el) {
   return el.meta_value;
})
