Create URL using a date-picker

I am using a simple html form using four input fields. On submit their values should generate an url like: input 1: 21.11.2015 input 2: 24.11.2015 input 3: 123 input 4: asd myurl.com/example&rooms=123&persons=asd&from=2015-11-21&to=2015-11-24 I am using "pick a day" as date picker. The form is used three times on the same page and should be synchronized. [login to view URL] The solution should be valid html and work on IE8+ (and mobile browsers). Feel free to check my demo: [login to view URL] I appreciate your help!
