保留表单值（例如下拉菜单和单选按钮）而不使用任何Web存储

Question

I have a form and wanted to retain its values when form loads without using any web storage.

I want to use only Javascript or jQuery. Moreover, I want that form values such as radio and dropdown selected value should retain its previous filled values.

Answer 1

You can either use browser cache or cookies to retain data on the client side. But both have their own limitations. Smartphone Browser native cache is about 5x times slower than local storage and information about cookies is sent to the server in the request header when a user visits a page that has cookies associated with it.
