获取文件大小 - 服务器端验证

Question

我试图做一个表单的服务器端验证与文件附件。我想不出正确的语法得到该文件的大小。我努力了：

form.myFile.files[0].size;
form.myFile.file.size;
form.myFile.getSize();

form.myFile.getName(); // this works and does return the name of the file.

---

It's just an html form that is submitted to a *.gs page. <input type="file" id="myFile"> Then, on the *.gs page - doGet() - then pulls in the form.

---

有任何想法吗？非常感谢！！！

Answer 1

form.myFile.length; // that worked!
