Javascript code for auto-advance on matrix format in Qualtrics -

-

i'm creating survey on qualtrics i'm hoping auto-advance next page after survey taker makes his/her choice on last question of matrix. have javascript code auto-advance after click on single-choice question need edit auto-advance on click of last single-choice question in matrix table: 

var = this; this.questionclick = function(event,element){     if (element.type == 'radio')  {        that.clicknextbutton();     } }

this can done programmatically using 2 more methods api; getchoices() , getselectedchoices(). allows write flexible code work regardless of order in choices selected or how many options presented.

var = this; var choices = this.getchoices( "radio" ).length; this.questionclick = function( event, element ){     var selected = that.getselectedchoices().length;     if ( choices  == selected )  {        that.clicknextbutton();     } }

we compare number of choices number of answers , progress once each statement has been answered.

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...
