Import Javascripts- Liferay 5

[Alberto Rigenti，修改在12 年前。]

Hi everybody,
I'm looking for a way to import javascript files, at page-level, that allows me to made changes on its without portal restart.
At the moment I import that as follow:

<script type="text/javascript">
	<%@ include file="../scripts/myscript.js" %>
</script>

This way it works as I want, but the Javascript code is replicated for every portlet in page.

Hi,

use liferay-portlet.xml and its <portlet-header-javascript>/scripts/myscript.js</portlet-header-javascript>. I assume you script is located in your <webapp_docroot>/scripts/ folder.

This way, for more portlets on the same page, script will be included only once.

See DTD of liferay-portlet.xml for more inrformation.

Yes, but in this way if you made any changes in the Javascripts you will not see that until you do not restart the portal.

I don't think its necessary. But I assume you have to run you Liferay in developer's mode. It's just a bunch of portal-ext properties, that disables compressing and bundling of JS and CSS files. Place this properties into separate file and inclide it in portla-ext.properties via

include-and-override=portal-developer.properties

I'm developing my files using this approach quite often. Try to have a look at portal-developer.properties in standard downloadable Liferay 6.0.6 bundle, it has some content like this:

theme.css.fast.load=false
theme.images.fast.load=false

javascript.fast.load=true
javascript.log.enabled=true

layout.template.cache.enabled=false

browser.launcher.url=

combo.check.timestamp=true

freemarker.engine.cache.storage=soft:1
freemarker.engine.modification.check.interval=0

openoffice.cache.enabled=false

velocity.engine.resource.manager.cache.enabled=false

com.liferay.portal.servlet.filters.cache.CacheFilter=false

com.liferay.portal.servlet.filters.themepreview.ThemePreviewFilter=true
