javascript 对象的比较是比较坑爹的一件事，因为javascript对象比较的是引用地址！当两个内容完全一样的对象比较：

var object1={            name:"1234 ",            code:123,            test:"321",        };        var object2={            name:"1234 ",            code:123,            test:"321",        };        console.log(object1==object2)   //false

解决方法使用hashcode

javascript hashcode实现

function hashcode(str) {  var hash = 0, i, chr, len;  if (str.length === 0) return hash;  for (i = 0, len = str.length; i < len; i++) {    chr   = str.charCodeAt(i);    hash  = ((hash << 5) - hash) + chr;     hash |= 0; // Convert to 32bit integer }  return hash; }

实例：

var object1={            name:"1234 ",            code:123,            test:"321",        };        var object2={            name:"1234 ",            code:123,            test:"321",        };        console.log(object1==object2)   //false        var test1=hashcode(JSON.stringify(object1));        var test2=hashcode(JSON.stringify(object2));        console.log(test1,test2,test1==test2);
