removing data by value from a json array

I had created two arrays to store an array of data into local storage. I'm storing it by creating an array of array. But not able to remove the value.

 `var divMappingArray = new Array();
 var data = new Array();

 data[0] = {"ID": 123, "Name": "temp" };
 divMappingArray.push(data[0]);
 data[1] = {"ID": 23, "Name": "temp1" };
 divMappingArray.push(data[1]);`

 localStorage.setItem('zoneObject', JSON.stringify(divMappingArray));

I'm saving this into local storage, but I need to remove a value based on name or id. I tried looping it and remove the item, but this is not working for me.

  $.each($.parseJSON(retrievedObject), function(i, value){
            delete value.ID[i];
    });

Parsing the array value by retrieving from local storage and want to add the updated data into local storage back. While removing i want to remove the whole set of array value both ID and name, the retrieved data length will be reduced after the removal.

After modifying the aray, you need to update the local storage

var rarray = $.parseJSON(retrievedObject);
$.each(rarray, function (i, value) {
    if (value.ID == 23) {
        rarray.splice(i, 1);
        return false;
    }
});
localStorage.setItem('zoneObject', JSON.stringify(rarray));

Demo: Fiddle
