dojo.query('form').children(':not(textarea)'); // returns [] <== bad

dojo.query('form').children().filter(':not(textarea)'); // returns [] <== bad

dojo.query('form>*:not(textarea)'); // returns [div.myClass, div.myClass] <== OK

I consider this a dupe of #9665, the issue mainly is that children() uses filter() underneath, and filter is limited to very simple selectors. For the second example, using query() instead of filter works:


So the fix for children() is to not use filterQueryResult (which is what filter() uses) and just a query call (what #9665 is tracking). However it will be a slower call.

I wouldn't mind changing dojo.NodeList?'s filter to just be an alias to query(), but it is a slight change in behavior (but for the good, allows more selectors?), and it will be slower, but I think not having the qualification about the types of selectors will make it easier to use.

Peter, Eugene, Alex, any thoughts on mapping dojo.NodeList?'s filter() to be just query()?

I'm curious how much slower the "enhanced" .query is compared to the "limited" filter.

dojox.jq compatibility layer will not match jQuery unless this ticket is fixed.

(In [20617]) Refs #10029: fixes the children() method and all NodeList?-traverse methods to use a slower dojo.query-based filter vs dojo._filterQueryResult. It allows more types of CSS selectors. Updated dojocampus docs for -travers. Leaving the ticket open to figure out what to do for dojo.NodeList?'s .filter method, but will be pushing that out to another milestone.

Resolution: fixed

It's working now, probably due to the new dojo/query module and related code.
