At one interview, once I attended, I was asked to create one java script based functionality in which I was said to create one form (say i.e first name, last name, email, age) and one listing(actually listing was kind of another form storing multiple entries) below this form. On submitting this form one new row was added to listing. However it is possible to remove any previously added listing row. and after adding removing, finally need to store this final state of listing. ( Kind of form post and server side scripting comes into picture )

So what I did that, On Form submit, adding a new <tr> row in listing table at the same time I serialized all form data except submit button using jQuery serialize and stored it in one hidden element of listing form.

On removing listing row, I was removing <tr> row along with respective hidden element for the same row.

All was working like great without any error. But the interviewer asked me that "The approach I used (hidden elements) was really proper?".

I replied, I could have used json? but Could not crack interview. So I want to know what is best approach that We can use to store data in such conditions?
