javascript - Style a d3 element with jQuery and CSS -

-

i have somehow technical question. know if there possibility style d3 element jquery.

for instance "collatz graph" example d3 site http://www.jasondavies.com/collatz-graph/ producing circle - nodes small labels.

in case numbers 1, 2, 3 , on. number nothing more piece of code e.g.

 <text dy=".31em" text-anchor="start" transform="rotate(90)translate(8)">32</text>

how style element jquery? e.g. adding red border clicking it?

obviously need class or id in <text ... > , proceed follows:

 $(".nome_class").click(function() {     $(this).css( "border", "3px solid red" );  });

in code, both d3 working (i can see graph) , jquery working (i can instance style or else regular html elements). when try style d3 element no result.

i grateful hint or advice.

to cut long answer short: don't it! try searching [svg][jquery] namespace on variety of problems might run when trying use jquery manipulate svg. although there ways around it, of them involve lot of tweaking , doing stuff in pure javascript no jquery involved.

jquery designed handle html results in difficulties dealing other namespaces svg. there bug reports on jquery's bug tracker jquery foundation has closed of them , @ time of writing lists these issues on won't fix page. there good answer question on has been awarded bounty giving more detailed insight technical problems involved.

i have myself combined both jquery , d3 separated use based on purpose designed for: jquery html manipulation , d3 dealing svgs.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
