try this out
delete locations[0];
You go through a normal JSON iteration like this
jQuery.each(locations, function(i, val) { if(val.zipcode == "yourvalue") // delete index { delete locations[i]; } });
something like that. are you looking for an idea or a complete function.
You could write a removeFirst function like this:
function removeFirst(arr, func) { for (var i=0; i<arr.length; i++) { if (func.call(arr[i])) { arr.splice(i,1); return arr; } } }
and then call it:
removeFirst(locations, function(){return this.zipcode=="06238";});
If you want to remove more then one element, you could write it like this:
function removeMany(arr, func) { for (var i=arr.length; i>0; i--) { if (func.call(arr[i])) { arr.splice(i,1); } } return arr; }
and use it in the same way.
Alternatively, use underscore (http://documentcloud.github.com/underscore) reject method in a similar way:
_.reject(locations, function(location){ return location.zipcode=="06238";});
Underscore is pretty good for doing array manipulations.
