Debugging

Here we discuss how to debug the client-side code. For server side debugging, please consult the IDE manual you use.

Debugger

First, it is suggested to get a debugger for the browser you're working with.

Browser	Debugger
Firefox	Firebug. It is not built-in, so you have to download and install it separately.
Firefox	ZKJet. This is a recommend debugging tool. It is not built-in, so you have to download and install it separately.
Internet Explorer 9	Developer Tools It is built-in and you could start it by pressing F12.

Turn Off Compression and Cache

By default, the JavaScript files (ZK packages) will be compressed and cached, which is hard to step in and debug. You could turn off the compression and the cache of JavaScript files by specifying the following in WEB-INF/zk.xml:

<client-config>
    <debug-js>true</debug-js>
</client-config>
<library-property>
    <name>org.zkoss.web.classWebResource.cache</name>
    <value>false</value>
</library-property>
