Object.prototype.equals = function(obj){

return true;

return false;
var length = 0; var length1=0;

示例如下：
var p1 = {name:"jack",age:18};
var p2 = {name:"lucy",age:10};
var p3 = {name:"jack",age:18};
console.log(p1.equals(p2));//false
console.log(p1.equals(p3));//true
console.log(p1.equals({name:"jack",age:18}));//true
