remove item from array using its name / value

Question

I have the following array

var countries = {};  countries.results = [     {id:'AF',name:'Afghanistan'},     {id:'AL',name:'Albania'},     {id:'DZ',name:'Algeria'} ]; 

How can I remove an item from this array using its name or id ?

Thank you

Answer 1

Created a handy function for this..

function findAndRemove(array, property, value) {   array.forEach(function(result, index) {     if(result[property] === value) {       //Remove from array       array.splice(index, 1);     }       }); }  //Checks countries.result for an object with a property of 'id' whose value is 'AF' //Then removes it ;p findAndRemove(countries.results, 'id', 'AF'); 

Answer 2

Array.prototype.removeValue = function(name, value){    var array = $.map(this, function(v,i){       return v[name] === value ? null : v;    });    this.length = 0; //clear original array    this.push.apply(this, array); //push all elements except the one we want to delete }  countries.results.removeValue('name', 'Albania');
