FormData追加不起作用

Question

In jQuery code,

var formData = new FormData($('#content-submit')[0]);
        formData.append("Title", $("input[name=Title]").val());
        formData.append("Url", $("input[name=Url]").val());
        formData.append("Content", $("textarea[name=Content]").text());
        formData.append("Genre", $("input[name=Genre]").val());
        formData.append("File", $("input[name=File]")[0].files[0]);
        console.log(formData);

But console.log says

FormData {}

So I think that FormData append method doesn't work. Are there other things that I should do?

Answer 1

FormData can't be inspected from the web developer console. You can only use them to create key value pairs to be sent.

If you want to debug it, you may do this,

for (var p of formData) {
  console.log(p);
}
