推荐答案

（ function ShowPopup（message）{

(function ShowPopup(message) {

（ function （） {
var message = 无效文件。请上传一个文件，其中包含 + extension：\ n\\\
+ validFilesTypes.join（ ，）;

(function () { var message = "Invalid File. Please upload a File with" + " extension:\n\n" + validFilesTypes.join(", ");

（< span class =code-string> ＃dialog）。html（message）;

("#dialog").html(message);
