Hi,

There shouldn't be any reason why not - you're not trying to put one in a server-side script, are you?

no,just a javascript in the webclient.

simple prompt code:


var name=prompt("sometext","defaultvalue");
‍‍‍

the error:

org.alfresco.error.AlfrescoRuntimeException: Error during command servlet processing: Failed to execute script 'workspace://SpacesStore/1118dbd7-464d-11dc-884d-adf88105aace': ReferenceError: "prompt" is not defined. (AlfrescoScript#1)

Ah, but that must be running on the server-side to throw that exception.

You can only prompt the user with client-side javascript, i.e. running in the browser via a <script> tag in the rendered HTML, not the Javascript API engine running on the server.

thanx… now it doesn't give an error anymore,but I still don't see the prompt.

freemarker link:


<a href="/alfresco/command/script/execute?scriptPath=/Company%20Home/Data%20Dictionary/Scripts//createproject.js&contextPath=/Company%20Home/Intranet/file.txt" ><h2>Create new project</h2></a>

‍‍‍‍

javascript code:


var name= "<script>prompt(\"sometext\",\"defaultvalue\");</script>";
name;
var myfolder = space.createFolder("Planning");
var myfolder = space.createFolder("Reporting");
var myfolder = space.createFolder("TA");
var goback = "<script>history.back();</script>"; 
goback;

‍‍‍‍‍‍‍‍‍‍

It just creates the folders but doesn't show the prompt

Hi,

You have to prompt the user on the client before invoking the createproject.js script, something like this:

<script type="text/javascript">
   function createNewProject(url)
   {
      var name = prompt("Type the name here", "defaultValue");
      location.href = url + "&name=" + name;
   }
</script>

<a href="#" onclick="createNewProject('/alfresco/command/script/execute?scriptPath=/Company%20Home/Data%20Dictionary/Scripts//createproject.js&contextPath=/Company%20Home/Intranet/file.txt'); return false;">
   <h2>Create new project</h2>
</a>
‍‍‍‍‍‍‍‍‍‍‍‍

Then you pull out the submitted name variable on the server and use that when creating your space.

Thanks,
Mike

another question

I've created a link(in freemarker) when users click on it, it makes some folders. Now I want to hide that link for users that don't have write acces in that folder. Is ist possible in alfresco 1.4?

Maybe I can sent the permissions back from the serverjavascript to the client javascript? or isn't this possible?

Hi Nick

Apologies - didn't see you tacked a new question onto that topic!

A "hasPermission" method was added to v1.4.3 - I'm not sure exactly which version you're on?

You should be able to do:

<#if hasPermission(TemplateNode node, String permission) == 1>
… show the link …
</#if>‍‍‍

"permission" would be either "Write" or "AddChildren" depending on your configuration.

<#if hasPermission(space, "Write") == 1>
… show the link …
</#if>‍‍‍

Mike

Hi Mike

really thx…
it works…

A last question

In my javascript I check if the spacename exists or not…

If the spacename already exists, The space may nog be created(duplicated names).
I did this,but I want to show the user a message that the space wasn't created because it already exists…(an alert isn't working because it's on server side)

Is this possible?

friendly regards,

Nick

Hi Nick,

I guess there are two ways:

1/ Where you return the HTML "<script>history.back();</script>" at the end of the server-side script, you can optionally add an alert() in there, i.e.

<script>alert('Duplicate space name found'); history.back();</script>‍

or
2/ Have the Freemarker template walk the child spaces and send an array of strings to do a client-side Javascript check in the createNewProject() function - so the duplicate name isn't allowed to be submitted.

I suspect #1 will be easier, although #2 might give a better user experience.

regards,
Mike

Thanks for this post - it was very helpful to me in creating a scripted action with confirmation prompt and alerts. It would be nicer if there was a way to do this on the server side but I assume that requires adding Java/JSP code.
