AppML - Environment

Quiz

It is very easy to use AppML. Simply refer the JavaScript file using <script> tag in HTML pages and deploy on a Web Server.

Web Server − PHP works with virtually all Web Server software, including Microsoft's Internet Information Server (IIS) but most often used is Apache Server. Download Apache for free here − https://httpd.apache.org/download.cgi

appml.js can be accessed in the following ways −

You can download appml.js from its official website

Now refer the file as shown in the following code.

<script type = 'text/javascript' src = 'appml.js'></script>

Update the src attribute to match the location where the downloaded files are kept.

You can refer to the appml.js library from W3Schools directly −

<script src = "https://www.w3schools.com/appml/2.0.3/appml.js" 
   type = "text/javascript"></script>

Note − In all the chapters for this tutorial, we have referred to W3Schools version of the AppML library.

Example

AppML is based on Model-View-Controller (MVC) pattern. Let's take a look at a simple example of AppML.

<!DOCTYPE html>
<html lang="en-US">
   <title>Students</title>
   <style>	  
      table {
         border-collapse: collapse;
         width: 100%;
      }

      th, td {
         text-align: left;
         padding: 8px;
      }

      tr:nth-child(even) {background-color: #f2f2f2;}
   </style>
   <script src="https://www.w3schools.com/appml/2.0.3/appml.js"></script>
<body>
   <table appml-data="students">
      <tr>
         <th>Student</th>
         <th>Class</th>
         <th>Section</th>
      </tr>
      <tr appml-repeat="records">
         <td>{{studentName}}</td>
         <td>{{class}}</td>
         <td>{{section}}</td>
      </tr>
   </table>
   <script>
   var students = {
      "records":[
         {"studentName":"Ramesh","class":"12","section":"White"},
         {"studentName":"Suresh","class":"12","section":"Red"},
         {"studentName":"Mohan","class":"12","section":"Red"},
         {"studentName":"Robert","class":"12","section":"Red"},
         {"studentName":"Julie","class":"12","section":"White"},
         {"studentName":"Ali","class":"12","section":"White"},
         {"studentName":"Harjeet","class":"12","section":"White"}
   ]};
   </script>
</body>
</html>

The following line refers to AppML library.

<script src = "https://www.w3schools.com/appml/2.0.3/appml.js" 
   type = "text/javascript"> </script>

This line refers AppML library.

We have added an attribute app-data to table to refers to students object. It can be json, txt, xml or even database model.

<p>First String: < input data-bind = "value: firstString" /> &lt/p>

This is how we are binding values from ViewModel to HTML elements using 'appml-data' attribute in the body section.

Output

Save the above code as my_first_appml_program.html. Deploy the files on a web server and access the file. Verify the output.

Download appml.php

Download the file from W3Schools https://www.w3schools.com/appml/2.0.3/appml.php.txt Copy the file to your web site and rename it to appml.php. It will be used to load appml model in coming examples.
