var index = {validate: function () { $("#uploadmodal").on('shown.bs.modal', function () { $("#submit").on('click', function (event) { event.stopPropagation(); if (index.validPhoto){ alert('success'); console.log(index.validPhoto); }else { alert('error'); console.log(index.validPhoto); } }) });},validPhoto:null,_validateFile: function () { $('#inputfile').checkFileTypeAndSize({ allowedExtensions: ['txt','png'], maxSize: 5000, success: function() { index[validPhoto] = true; }, extensionerror: function() { alert('允许的格式为:txt,png !'); index[validPhoto] = false; }, sizeerror: function() { alert('最大尺寸500KB !'); index.validPhoto = false; } });},我想通过下面的函数验证文件是否符合规则,想法是通过验证规则修改validphoto,之后将validphoto传入,但是修改不成功,求指点 是不是这种写法就不对呢
