Javascript: Remove object from array on function call to object

Question

Not quite sure how to phrase this question (I am sure it has been asked before in some form).

My problem is essentially shown below (through some badly written pseudo-javascript code):

var list = []
for (i to somenumber)
    list.push(new myObject);

list.foreach(function(item){
    if (item.name === 'WhatIAmLookingFor')
        item.delete() <--- This needs to remove the object from list
}

So as my amazing code alludes to I want to be able to remove the item from the list by calling a function on an object in the list.

Sorry if this is an ignorant question but I cant figure out how to do this.

Answer 1

Instead of deleting items, use filter to keep only "good" ones.

 var list = [ { name: 'foo' }, { name: 'bar' }, { name: 'removeMe' }, { name: 'baz' } ]; list = list.filter(function(item) { return item.name != 'removeMe' }); document.write(JSON.stringify(list)) 

To remove an element "inside out", eg element.removeFrom(list) , you need array.splice :

 obj = function(name) { this.name = name; this.removeFrom = function(lst) { for (var i = 0; i < lst.length; ) { if (lst[i].name == this.name) lst.splice(i, 1); else i++; } } } a = new obj('a'); b = new obj('b'); c = new obj('c'); x = new obj('remove'); list = [a, b, c, x, x, a, b, c, x] x.removeFrom(list) document.write(JSON.stringify(list))
