47.17 Generating Pages using Objects
Instead of using functions/methods to generate HTML pages, we can use an object for each element in the page.
This choice means more beautiful code but slower.
The fastest method is to print HTML code directly, then using functions then using templates then using objects
(slower).
#!c:ringbinring.exe -cgi
Load "weblib.ring"
Import System.Web
Func Main
WebPage()
{
Title = "Using objects to create the Web Page content"
h1 { text("welcome") }
link
{
Title = "Google"
Link = "http://www.google.com"
}
div
{
id = "div1"
style = stylegradient(30) + stylesize("50%","50%")
text("Outer Div")
div
{
id = "div2"
color = "white"
backgroundcolor = "green"
width = "50%"
height = "50%"
marginleft = "5%"
margintop = "5%"
text("Inner Div")
}
}
div
{
id = "div3"
color = "black"
backgroundcolor = "silver"
width = "100%"
height = "100%"
text("Form")
form
{
method = "POST"
Action = "helloworld.ring"
Table
{
style = stylewidth("100%") + stylegradient(24)
TR
{
TD { WIDTH="10%" text("Name : " ) }

47.18 HtmlPage Class
Using this class we can create HTML documents without printing the output to the standard output
So instead of using the WebLib in Web Applications only
We can use it in Console/GUI/Mobile Applications too
Example:
load "stdlib.ring"
load "weblib.ring"
import System.Web
47.18. HtmlPage Class 389
6. Ring Documentation, Release 1.5.2
func main
mypage = new HtmlPage {
h1 { text("Customers Report") }
Table
{
style = stylewidth("100%") + stylegradient(4)
TR
{
TD { WIDTH="10%" text("Customers Count : " ) }
TD { text (100) }
}
}
Table
{
style = stylewidth("100%") + stylegradient(26)
TR
{
style = stylewidth("100%") + stylegradient(24)
TD { text("Name " ) }
TD { text("Age" ) }
TD { text("Country" ) }
TD { text("Job" ) }
TD { text("Company" ) }
}
for x = 1 to 100
TR
{
TD { text("Test" ) }
TD { text("30" ) }
TD { text("Egypt" ) }
TD { text("Sales" ) }
TD { text("Future" ) }
}
next
}
}
write("report.html",mypage.output())
47.19 Using Bootstrap Library using Functions
The next example uses the Bootstrap JavaScript Library when generating the HTML page.
#!c:ringbinring.exe -cgi
Load "weblib.ring"
Import System.Web
Func Main
new BootstrapPage {
divstart([ :class = "container" ])
divstart([ :class = "jumbotron" ])
h1("Bootstrap Page")
divend()

7. Ring Documentation, Release 1.5.2
divstart([ :class = :row ])
divstart([ :class = "col-sm-4" ])
h3("Welcome to the Ring programming language")
p([ :text = "Using a scripting language is very fun!" ])
divend()
divstart([ :class = "col-sm-4" ])
h3("Welcome to the Ring programming language")
p([ :text = "using a scripting language is very fun!" ])
divend()
divstart([ :class = "col-sm-4" ])
h3("Welcome to the Ring programming language")
p([ :text = "using a scripting language is very fun!" ])
divend()
divend()
divend()
}

47.21 CRUD Example using MVC
The next example uses the weblib.ring & datalib.ring.
The datalib.ring contains classes for creating database applications using MVC pattern.
In this example we create an object from the SalaryController class then call the Routing method.
We define the website variable to contains the basic url of the page.
When we create the SalaryModel class from the ModelBase class, the salary table will be opened and the columns
data will be defined as attributes in the model class.
The SalaryView class create an object from the SalaryLanguageEnglish class to be used for translation.
The method AddFuncScript is used to call the form for adding/modifying record data.
The method FormViewContent is used to determine the controls in the form when we add or modify a record.
#!c:ringbinring.exe -cgi
Load "weblib.ring"
Load "datalib.ring"
Import System.Web
website = "ex24.ring"
New SalaryController { Routing() }
