[dancer-users] Getting param name of dynamically named <input> tag

[Amelia Ireland]

Most browsers have functionality for web development that allows you to
examine a page, view the generated markup, and so on. In FireFox, for
example, it's under Tools > Web Developer > Inspector, or in Chrome, it's
under View > Developer > Developer Tools. You can zero in on the form and
the elements generated by this bit of javascript to find out the input
names.
