jquery - Designing a Play Framework which uses Ajax, but also cares about SEO and graceful degradation -


what way design web app play, provides graceful degradation? working on client application, uses ajax grab partial views, , jquery, put them in place dom.

to support seo , graceful degradation, should either make duplicate controller method, renders partial view part of whole page (header , footer included).so when make call jquery, call "item/12345/partial", bring partial view when user goes "item/12345" should show entire page, partial stuck in.

the second option avoid second controller method, , return full page content (header,javascripts, styles,partial, , footer). when invoked jquery, callback method strip necessary html , fit dom. of course, means same amount of content returned server, reduces advantages of using ajax in first place.

which 1 recommend?

second option not me. use on our project have base template extended ajax parts , these parts have not load rest of template on ajax request:

#{ifnot request.ajax}     #{extends 'search-main.html' /} #{/ifnot}

and search-main.html has #{dolayout /} in place ajax section should occur if full page going rendered (non ajax request). value in request.ajax set play, don't have figure out yourself.

about duplicated controllers: should able map 1 controller many urls if needed. add them routes file. not required in our approach.

i can draw multiple lines on canvas; added layer using drawscene dlayera1.add(line); line.getpoints()[0].x = mousepos.x; line.getpoints()[0].y = mousepos.y; line.getpoints()[1].x = mousepos.x; line.getpoints()[1].y = mousepos.y; moving = true; dlayera1.drawscene(); http://jsfiddle.net/user373721/xzead/1/ . is there way delete individual line? currently, you'll have modify points array this: line.getpoints()[0].splice(index, 1); since arrays modified reference, modifying returned array modifies "source of truth" points array attr
