Javascript-从引用中删除对象

Question

I have one tree-like structure containing block with certain id. Then I have another object, that contains 'id' : objectPart pairs.

Tree:

var tree = [
    {
        'property' : 'value',
        'id' : 'someID',
        //more properties...,
        'content' : [
            {
                'prop' : 'something',
                ...
            }
        ]
    },
    {
        'prop' : 'val',
        ...
        'content' : []
    }
]

ID index:

{
    'someID' : tree[0]
}

I need some way how when I do delete ID_index.someID , that object gets also deleted from main structure.

Structure after this code should look like this:

[
    {
        'prop' : 'val',
        ...
        'content' : []
    }
]

Instead of using delete you can write your own remove function. It should look like this:

function myRemove(stringId) {
    delete ID_index[stringId]; //remove property from ID_index
    objIndex = ... //find object index in tree array
    tree.splice(objIndex, 1); //remove object from tree array
}
