This article mainly introduces how to use js to dynamically add text boxes at the front end and sample code for obtaining text box content at the backend. If you need it, you can refer to it for help. There are two pages: 1. create. jsp The Code is as follows: Ii. Receiving data page request.

Label: style blog HTTP Io color OS ar Java Recently, I found a problem. When I access Servlet and use redirection to jump to the page with Chinese parameters, I found that the address bar could not find the parameter as Chinese. For a moment, I will discuss the cause of Garbled text: the contents in the URL address bar are generally ISO-8859-1 encoded, so, if we use redirection, it is to re-modify the content in the address bar (URL ), so if we want to add Chinese parameters to the URL, We mus
