[OmniFaces utilities 2.2/2.3] Add given JavaScript resource to end of head/body of the current view


[OmniFaces utilities] The addScriptResourceToBody() adds the given JavaScript resource to end of body of the current view.
[OmniFaces utilities] The addScriptResourceToHead() adds the given JavaScript resource to end of head of the current view.

Note: This doesn't have any effect during non-@all ajax postbacks.

Methods:
Usage:

Let's suppose that we have the following /resources folder structure in a JSF application (practically, we have two scripts directly in /resources, two scripts in the default library, and two scripts in the default library, /scripts sub-folder):

Further let's have several examples of using the Components#addScriptResourceToBody() and Components#addScriptResourceToHead() utility methods.

·         programmatically adding the /resources/default/scripts/toBody.js as a resource to end of body of the current view:

import org.omnifaces.util.Components;
...
UIComponent comp = Components.addScriptResourceToBody("default", "scripts/toBody.js"); 

The produced markup will be:

<html xmlns= ...>
 <body>
 ...
 <script type="text/javascript" src="/MyApp/faces/javax.faces.resource/scripts/toBody.js?ln=default"></script>
 </body>
</html>

·         programmatically adding the /resources/default/scripts/toHead.js as a resource to end of head of the current view:

import org.omnifaces.util.Components;
...
UIComponent comp = Components.addScriptResourceToHead("default", "scripts/toHead.js"); 

The produced markup will be:

<html xmlns= ...>
 <head>
  ...
  <script type="text/javascript" src="/MyApp/faces/javax.faces.resource/scripts/toHead.js?ln=default"></script>
 </head>
</html>

·         programmatically adding the /resources/default/toBody.js as a resource to end of body of the current view:

import org.omnifaces.util.Components;
...
UIComponent comp = Components.addScriptResourceToBody("default", "toBody.js"); 

The produced markup will be:

<html xmlns= ...>
 <body>
 ...
 <script type="text/javascript" src="/MyApp/faces/javax.faces.resource/toBody.js?ln=default"></script>
 </body>
</html>

·         programmatically adding the /resources/default/toHead.js as a resource to end of head of the current view:

import org.omnifaces.util.Components;
...
UIComponent comp = Components.addScriptResourceToHead("default", "toHead.js"); 

The produced markup will be:

<html xmlns= ...>
 <head>
  ...
  <script type="text/javascript" src="/MyApp/faces/javax.faces.resource/toHead.js?ln=default"></script>
 </head>
</html>

·         programmatically adding the /resources/toBody.js as a resource to end of body of the current view:

import org.omnifaces.util.Components;
...
UIComponent comp = Components.addScriptResourceToBody(null, "toBody.js"); 

The produced markup will be:

<html xmlns= ...>
 <body>
 ...
 <script type="text/javascript" src="/MyApp/faces/javax.faces.resource/toBody.js"></script>
 </body>
</html>

·         programmatically adding the /resources/toHead.js as a resource to end of head of the current view:

import org.omnifaces.util.Components;
...
UIComponent comp = Components.addScriptResourceToHead(null, "toHead.js"); 

The produced markup will be:

<html xmlns= ...>
 <head>
  ...
  <script type="text/javascript" src="/MyApp/faces/javax.faces.resource/toHead.js"></script>
 </head>
</html>
