您不能.但是您可以在 submit 事件中调用一个函数可以动态验证文件，并在 validation 选项.

You cannot. But you can call a function within the submit event which can dynamically validate files, and set some "base" validators in the validation option.

validation: {
// set default options such as making sure all uploads are images 
// or within a certain size.
},

onSubmit: function (id, name) {

   var file = this.getFile(id),
       validated = validate(file);
   if (validated) return true;
   else return false;
}

如果此函数返回false，则该项目将不被标记为已验证并且不会被上传.如果此函数返回true，则您在选项中设置的验证程序将在之后遍历文件.

If this function returns false, then the item will not be marked as validated and not be uploaded. If this function returns true, then the validators you set in the options will be ran over the file(s) afterwards.
