Iterate assocs in javascript to remove them

loftux

How do I iterate an associations of a specified type in javascript in order to remove them?
I've tried this (and some variants), but it does not work.

for (i in fileNode.assocs["xel:reviewedby"]){
   fileNode.removeAssociation(fileNode.assocs["xel:reviewedby"][i], "xel:reviewedby"); 
}‍‍‍

So what is the correct way?

Hi,

In your for…in loop the variable "i" is set to the value of the object within the array being iterated over, not the current index in the array.

Try this ….

for (var targetNode in fileNode.assocs["xel:reviewedby"])
{
   fileNode.removeAssociation(targetNode, "xel:reviewedby"); 
}

Thanks for the reply.
It doesn't work, have created this test code

var namesuffix = userhome.children.length; //to make file name unique

var sourceNode = userhome.createNode("testassocsfile"+namesuffix +".txt", "cm:content");
sourceNode.content = "the original text";
sourceNode.addAspect("cm:attachable");
logger.log("LX Created source node");

var destNode = userhome.createNode("attached1-"+namesuffix +".txt", "cm:content");
destNode.content = "Text in attached document";
logger.log("LX Created dest node 1");
sourceNode.createAssociation(destNode, "cm:attachments");
logger.log("LX Created assoc destNode to sourceNode");

var destNode2 = userhome.createNode("attached2-"+namesuffix +".txt", "cm:content");
destNode2.content = "Text in attached document2";
logger.log("LX Created dest node 2");
sourceNode.createAssociation(destNode2, "cm:attachments");
logger.log("LX Created assoc destNode2 to sourceNode");

sourceNode.save();

for (var targetNode in sourceNode.assocs["cm:attachments"])
{
   logger.log("LX Removing " + targetNode) //targetNode returns integer here
   logger.log("LX Removing name " + targetNode.name) //returns undefined
   sourceNode.removeAssociation(targetNode, "cm:attachments"); 
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

When this code is run, it throws error (partial)

Caused by: org.alfresco.error.AlfrescoRuntimeException: 08210080 Can't find method org.alfresco.repo.jscript.ScriptNode.removeAssociation(string,string). (file:/opt/alfresco/xelerated/tomcat/webapps/alfresco/WEB-INF/classes/alfresco/templates/webscripts/test/lxtest.get.js#30)

As you can see in my test code, the logging of targetNode in the iteration returns an integer, starting at 0 (and why I tried to use it the way I did, I think…).

I tried to change to sourceNode.removeAssociation(targetNode.child, "cm:attachments");
but that didn't work either.

Running this code on 3.3g

Hi,

Yes, my bad. The form you where using does indeed return the index of the array being iterated over …

// example iterating array indexes using 'for .. in'
var out1 = "";
for (i in userhome.children)
{
   out1 += userhome.children[i].name + "<br>";
}

// example iterating array values using 'for each .. in'
var out2 = "";
for each (n in userhome.children)
{
   out2 += n.name + "<br>";
}

I need to go back to JavaScript school!

Cheers,

OK,
this is how you do it for my example code

for each (targetNode in sourceNode.assocs["cm:attachments"])
{
&nbsp;&nbsp;&nbsp;sourceNode.removeAssociation(targetNode, "cm:attachments"); 
}‍‍‍‍
