//有时候 :on-success，:on-error 这个函数会无法调用，之前看另一个帖子是用的:onError="uploadError" :onSuccess="uploadSuccess"

2018-01-12: 昨天又遇到上传成功但是无法调用成功回调函数的问题，这里涉及到vue的生命周期，导致无法调用，js也不会报错，把对应函数放到methods顶部可解决。
// 上传成功后的回调 uploadSuccess (response) { let code = response.returncode; let msg = response.msg; this.open(msg, code); }, // 上传错误 uploadError (response) { this.open("500", "文件导入异常！"); },
