JavaScript determines whether a variable is an array of methods (array)

no more nonsense. Direct Previous code: 1, here is a general method of detection

/* * Determine if it is an array */ function IsArray (obj) {    return Object.prototype.toString.call (obj) = = ' [Object Array] ';}

2. How to Judge jquery

var result=$.isarray (obj);

3. instanceof operator

var ary = [1,23,4instanceof Array]//true;

Summary: cannot be detected with typeof because the array and object use typeof detection results are "object";
