Iterating collections

michaelc — Wed, 03 Jul 2013 21:05:37 GMT

having all sorts of problems with the backend JavaScript, it's not the JavaScript I know. So the method I have used to iterate a collection are not working for me. for ( var i=0; i<context.properties.section.sections.length;i++){ x = context.properties.section.sections; }‍‍

I think I have my answer, not what I expected.
I dumped the properties methods for a section and found.

indexOf,notifyAll,removeAll,containsAll,contains,empty,equals,notify,subList,class,set,isEmpty,add
size,iterator,clear,wait,listIterator,toString,retainAll …

size returned 7 good, but tried to use in a for loop and the loop failed.
this does seem to work.
   var itr = context.properties.section.sections.iterator();
   while(itr.hasNext()) {
       sectionObj = itr.next();
       sectionPath.push(sectionObj.path);
    }


So this is far more Java then JavaScript.

ok this is Java and not javascript at all.
I had the following statement
if (sectionObj.path == sectionPath){

}
this was never true, even when the values matched.
then I did the following
if (sectionObj.path.equals(sectionPath){

and it worked as expected.
