Answer 1

It worker for me.

  arrList = $.grep(arrList, function (e) { 

        if(e.add_task == addTask && e.worker_id == worker_id) {
            return false;
        } else {
            return true;
        }
    });

It returns an array without that object.

Hope it helps.

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.

Answer 3

Simply just pass the index

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.
