Question

I have an array of items like:

var items = [id: "animal", type: "cat", cute: "yes"]

And I’m trying to remove any items that match the ID given. In this case; animal

I’m stuck! I can get it to work easily by having a more simpler array but this is not what I need… I also need to remove the item by value as I don’t want the hassle of referring to items by their index.

Is there a jQuery method I could use where I don’t need to iterate through the items array, rather specify a selector?

Here is my jsFiddle: http://jsfiddle.net/zafrX/

I’m not sure how much of a hassle it is to refer to array items by index. The standard way to remove array items is with the splice method

for (var i = 0; i < items.length; i++)
    if (items[i] === "animal") { 
        items.splice(i, 1);
        break;
    }

And of course you can generalize this into a helper function so you don’t have to duplicate this everywhere.

EDIT

I just noticed this incorrect syntax:

var items = [id: "animal", type: "cat", cute: "yes"]

Did you want something like this:

 var items = [ {id: "animal",  type: "cat", cute: "yes"}, {id: "mouse",  type: "rodent", cute: "no"}];

That would change the removal code to this:

for (var i = 0; i < items.length; i++)
    if (items[i].id && items[i].id === "animal") { 
        items.splice(i, 1);
        break;
    }
