我一直在开发一个网站,该网站将提供人们创建的时间表。我正在使用Alienware进行开发,而ajax代码始终可以在笔记本电脑上完美运行。我正在使用IE。但是,如果我通过Samsung Smart TV或HTC U11手机访问站点,则Ajax不一致。它显示了我要的数据,但是,当我汇总一周的总时数时,有时会显示正确的小时数,有时会为用户安排一周的时数,显示0小时。为什么设备之间不一致?我知道Ajax建议用于IE。就像我说的那样,有时它会显示正确的每周总时数,而有时它只会显示零。我的Alienware上没有发生此问题。
我已经尝试使用onload代替onreadystatechange。我已将请求设置为异步和同步。无论在其他设备上将其设置为true还是false,都无法保持一致。我已经尝试过将其作为post和get方法,但两者也都不一致。我的代码有什么问题?
