Yes there are wiki docs here:
http://wiki.alfresco.com/wiki/Externalised_Client_Actions

Parameters for javascript actions and standard method based actions are this config block:


<params>
<param name="id">#{actionContext.id}</param>
<param name="dummy">dummy1</param>
</params> 
‍‍‍‍‍‍

So in this example the "id" arg will be set to the ID of the node the action is running on, and the "dummy" arg will be set to the value of "dummy1".

Note that the args are made available in the 'args' object as name/value pairs as mentioned in the wiki docs.

Cheers,

Kevin

Hello Kevin,

First of all thanks for the pointer to the Wiki. But i am still not there, still no
parameters in my script. I have done the following. I started of by adding a custom menu item and then i gave the menu something to call namely the script: myparams.js

I configured the following in web-client-config-custom.xml:

    <config>
       <actions>
       <!– Launch js_test Dialog –>
            <action id="js_test">
                <label>Test javascript</label>
                <image>/images/icons/add.gif</image>
                <script>/Company Home/Data Dictionary/Scripts/myparams.js</script>
                <params>
                   <param name="dummy">dummy1</param>
                  <param name="id">#{actionContext.id}</param>
               </params>
            </action>

            <!– Add action to more actions menu for each document–>
            <action-group id="document_browse_menu">
                <action idref="js_test" />
            </action-group>
       </actions>
    </config>

The myparams.js script looks like this:

logger.log("–>");

logger.log ("companyhome: " + companyhome)

var mydummy = args["dummy"];
var myid = args["id"];
logger.log("args[0] " + args[0] + " mydummy: " + mydummy + " myid : "+ myid);

logger.log("<–");

And the logger writes the following output:

16:28:39,781 DEBUG [repo.jscript.RhinoScriptService] Executing script: workspace
://SpacesStore/7cb09a38-6cc4-11db-93a1-a3f83372d0ec

16:28:39,796 DEBUG [repo.jscript.ScriptLogger] <–
16:28:39,796 DEBUG [repo.jscript.RhinoScriptService] Time to execute script: 15ms

As you can see both dummy and id are null.

This is really all the configuration and code i customized in Alfresco.
What am i missing or doing wrong here?

Thanks in advance!

Kind regards,

Ronald Vermeire

Can I ask which version of Alfresco you are using, as I'm wondering if you have an earlier version which does not have parameter passing enabled (this is a guess…)

Thanks,

Kevin

I am using alfresco 1.4. Today i saw a very simular question on this forum.

http://forums.alfresco.com/viewtopic.php?t=3952

But no answers till now, so i am getting curious if this feature is really
available in the current release.

If you read that post you'll see that the "id" parameter is working fine for him, but the others he is trying won't work as they are not primative types - i will reply to it shortly.

I'll take a look at this today, but i'm 99% sure it is working with basic types passed as parameters.

Thanks,

Kevin

Hello,

I read the other post again and now it worked for him. When i saw your answer i tried some things and i now know what the problem is!

                   <action-group id="document_browse_menu">
            <action idref="test_js" />
         </action-group>

This one does not work

         <action-group id="doc_details_actions">
            <action idref="test_js" />
         </action-group>

This one does not work

         <action-group id="document_browse">
            <action idref="test_js" />
         </action-group>

This one does work

Is this all how it should work, or should i be able to get actionContext.id from document_browse_menu and doc_details_actions?

Kind regards,

Ronald Vermeire

Re: context in javascript action

kevinr — Tue, 07 Nov 2006 11:23:23 GMT

Glad to hear it. That's rather odd - all those menus have a Node context passed in, so #{actionContext.id} should always be available.

I'm not sure why it's not working for the script execution as other actions within the same actiongroups all access #{actionContext.id} with no problem - otherwise nothing in the app would be working! If i get time today i'll try your exact use-case in those actiongroups.

Thanks,

Kevin

Hello,

In this post:

http://forums.alfresco.com/viewtopic.php?t=3952

Mitesh Panchal has the following code to get the current Node.

var curForum;
forums = companyhome.childByNamePath("Forums");
logger.log(forums.name);
forumsChildren =forums.children;

for(i=0;i<forumsChildren .length;i++)
{
    child =forumsChildren[i];
       if(child.id.equals(args["id"]))
    {
          curForum = child;
          logger.log("Current Forum Name : " + curForum .name);

     }
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

He asks if there is alternative way to find that node and i have exactly the same question. Because with hundred thousands nodes in the repository in different spaces it could take a long time before finding the correct node. So my question is, is there an alternative way?

Kind regards,

Ronald Vermeire

Re: context in javascript action

kevinr — Wed, 08 Nov 2006 14:46:15 GMT

Depends what you mean by "current" - I also said this in that forum thread:

you can pass the ID for the space e.g. SpaceDetailsBean.space.id should work ok. Of course SpaceDetailsBean.space.id is only valid when in the context of the Space Details dialog page. Generally the "current" space can be found using:
NavigationBean.currentNodeId

So SpaceDetailsBean.space.id will return the ID of the node for the current space if you are in the Space Details screen, and NavigationBean.currentNodeId will return the ID of the node for the current space if you are browsing around.

Thanks,

Kevin

Hello,

My question realy is how do i get a 'document' Node object from the simple type actionContext.id or the 'space' Node object from the simple type SpaceDetailsBean.space.id. I already tried NavigationBean.currentNode.path and then in my script companyhome.childByNamePath but that didn't work.

Kind regards,

Hello,

I finally managed it by using:

companyhome.childrenByXPath("//*[@cm:name='"+ myNodename + "']")‍

But this took 12125 ms which i found quit long , isn't there an alternative ?
The most logical to me would be a method like getNode(nodeId) .

What are your thoughts?

Kind regards,

Re: context in javascript action

kevinr — Thu, 09 Nov 2006 09:13:42 GMT

This is a little embarrassing - as there is already a method to help you do exactly that but I had forgotten to document it :roll:

I've added the documentation for the search.findNode(ref) method which you can easily use to find a node by ID:
http://wiki.alfresco.com/wiki/JavaScript_API#Search_API

Example:


var id = args["id"];   // assume the 'id' arg contains a node id
var node = search.findNode("workspace://SpacesStore/" + id);
if (node != null)
{
   // we found the node…
}
‍‍‍‍‍‍‍‍

Kevin
