JavaScript Packaging

If you'd like to customize the client-side behavior, it will end up with some JavaScript code. The can be packaged in several ways depending on the size and re-usability.

Embed the JavaScript Code Directly

Use the script directive to embed the code directly. For example,

<!-- foo.zul -->
<?script type="text/javascript" content="jq.IE6_ALPHAFIX='.png';"?>

Alternatively, you could use the script component to embed the code.

Put in a Separate File and Reference it in the ZUML page

If there are a lot of JavaScript code, it is better to package them in a separate file, and then use the script directive to reference the file in every ZUML page that requires it.

<!-- foo.zul -->
<?script type="text/javascript" src="/myjs/foo.js"?>

Put in a Separate File and Reference it in Language Addon

If the JavaScript code will be used in every ZUML pages, it is better to package them in a separate file, and then make it part of the the language definition. To make it part of the language definition, you could specify the following content in the language addon, say, WEB-INF/lang-addon.xml:

<language-addon>
    <javascript src="/myjs/foo.js"/>
</language-addon>

Then, you could specify the language addon in WEB-INF/zk.xml:

<language-config>
    <addon-uri>/WEB-INF/lang-addon.xml</addon-uri>
</language-config>
