This document provides examples of generating different HTML elements like lists, tables, and images using Ring functions. It shows how to create an unordered list from a Ring list and loop through numbers. Examples are given for generating a table with headers and cells, and displaying a random image from a folder. Functions like ulstart(), liend(), tablestart(), and cellend() are used to output the HTML.

- 8. Ring Documentation, Release 1.5.1 47.14 HTML Lists The next example print a list contains numbers from 1 to 10 Then print a list from Ring List. Finally we have a list of buttons and when we press on a button we get a message contains the clicked button number. To start the list we uses the ulstart() function. To end the list we uses the ulend() function. We uses listart() and liend() to determine the list item. #!c:ringbinring.exe -cgi Load "weblib.ring" Import System.Web Func Main New Page { ulstart([]) for x = 1 to 10 listart([]) text(x) liend() next ulend() list2ul(["one","two","three","four","five"]) ulstart([]) for x = 1 to 10 listart([]) 47.14.

- 10. Ring Documentation, Release 1.5.1 47.15 HTML Tables In this example we will learn how to generate HTML tables using the tablestart(), tableend(), rowstart(), rowend() ,headerstart(), headerend(), cellstart() and cellend() functions. #!c:ringbinring.exe -cgi Load "weblib.ring" Import System.Web Func Main New Page { divstart([ :style = styledivcenter("400px","500px") ] ) style(styletable() + styletablerows("t01")) tablestart([ :id = :t01 , :style = stylewidth("100%") ]) rowstart([]) headerstart([]) text("Number") headerend() headerstart([]) text("square") headerend() rowend() for x = 1 to 10 rowstart([]) cellstart([]) text(x) cellend() cellstart([]) text(x*x) cellend() rowend() next tableend() divend() } Screen Shot: 47.15.
