Começando com Haxe/JS

Documentação > start > Começando com Haxe/JS

Developing Javascript code is really easy with Haxe. Let's see our first HelloWorld sample :

class Test {
    static function main() {
        trace("Hello World !");
    }
}

Put this class into a file named Test.hx and create the file compile.hxml in the same directory with the following content :

-js test.js
-main Test

To compile, you can simply double-click on the compile.hxml file (or run the command haxe compile.hxml). If an error occur, it will be displayed. If everything went smoothly like it should, this will produce a file named test.js that can be embedded into an HTML page such as this one :

<html>
<head><title>Haxe JS</title></head>
<body>

<div id="haxe:trace"></div>
<script type="text/javascript" src="test.js"></script>

</body>
</html>

If you put since code into a file named test.html and open it with your webbrowser, it should display Hello World with information about file and line the trace occured. Please note that a div block is needed to display the Haxe Javascript traces.

Using Alert

The possibility to display some text is to use alert. Modify Test.hx with the following content : 

class Test {
    static function main() {
        js.Lib.alert(js.Lib.window.location.href);
    }
}

Compile and open the test.html. It should display a window message box displaying the current location URL.

Watch the available APIs from Lib .
