How do I remove an object from an array with JavaScript? [duplicate]

Question

I have an JavaScript object like this:

id="1"; name = "serdar"; 

and I have an Array which contains many objects of above. How can I remove an object from that array such as like that:

obj[1].remove(); 

Answer 1

Well splice works:

var arr = [{id:1,name:'serdar'}]; arr.splice(0,1); // [] 

Do NOT use the delete operator on Arrays. delete will not remove an entry from an Array, it will simply replace it with undefined.

var arr = [0,1,2]; delete arr[1]; // [0, undefined, 2] 

But maybe you want something like this?

var removeByAttr = function(arr, attr, value){     var i = arr.length;     while(i--){        if( arr[i]             && arr[i].hasOwnProperty(attr)             && (arguments.length > 2 && arr[i][attr] === value ) ){              arr.splice(i,1);         }     }     return arr; } 

Just an example below.

var arr = [{id:1,name:'serdar'}, {id:2,name:'alfalfa'},{id:3,name:'joe'}]; removeByAttr(arr, 'id', 1);    // [{id:2,name:'alfalfa'}, {id:3,name:'joe'}]  removeByAttr(arr, 'name', 'joe'); // [{id:2,name:'alfalfa'}]
