本文实例讲述了javascript获得指定对象大小的方法。分享给大家供大家参考。具体如下：
function objectsize(the_object) { /* function to validate the existence of each key in the object to get the number of valid keys. */ var object_size = 0; for (key in the_object){ if (the_object.hasownproperty(key)) { object_size++; } } return object_size;}
用法如下：
// arbitrary objectvar something = { dog: cat, cat: dog}console.log(objectsize(something));// logs: 2
希望本文所述对大家的javascript程序设计有所帮助。
