In this very first post, i will write a simple extjs tutorial displaying an alert MessageBox contain text Hello World as an introduction in learning extjs. Before we start if you use firefox i suggest you to installing firebug. Firebug is very useful for debugging our extjs application if we found error on our application. In this tutorial i use extjs version 3.3.1.
Okay lets start.
1. Create a file and name it hello-world.html using your code editor. We need to add this lines of code and its required in order to our extjs application work correctly. Add this lines of code before </head> tag on your html file.
<link rel="stylesheet" href="ext-3.3.1/resources/css/ext-all.css" /> <script type="text/javascript" src="ext-3.3.1/adapter/ext/ext-base.js"></script> <script type="text/javascript" src="ext-3.3.1/ext-all.js"></script>
2. If done add this lines of code after the codes above.
<script type="text/javascript">
Ext.onReady(function() {
Ext.MessageBox.alert('Message', 'Hello World');
});
</script>
the codes above will display an ExtJS Alert MessageBox contain text Hello World.
here the complete codes

});
</script>
