label[for] attributes aren't updated when dynamically creating new inlines

[Matthias Kestenholz]

Processing for attributes too in inlines.js, addButton click handler fixes the problem.

Something like this:

                                        var el = $(this);

+                                   }).each(function() {
+                                       var el = $(this);
+                                       el.attr("for", el.attr("for").replace(/__prefix__/g, nextIndex));
+                                   })
+                                   .end()
+                                   .filter(function() {
+                                       var el = $(this);
                                        return el.attr("name") && el.attr("name").search(/__prefix__/) >= 0;
                                    }).each(function() {
                                        var el = $(this);

I'm not sure whether this is the best way to fix it, though. Processing a list of elements six times instead of once does not seem to make much sense to me.

This code isn't performance critical, though.

Could this be solved with an approach similar to the one proposed in #14830 ?

[Matthias Kestenholz]

Both problems affect the inline javascript code, but the issues are different.

As I understand it, #14830 covers the problem that input[type=radio] elements are inserted too early into the DOM (before all IDs and NAMEs are changed). This ticket covers the problem that not all attributes which should be unique are updated properly, in this case the FOR attribute of label tags.

Maybe both bugs should be resolved at the same time, but that's not for me to decide.

Duplicate of #13674, it has a simpler patch attached, and the fix suggested by the OP there is very similar to the one proposed here.
