javascript - Replacing a href link using jQuery .attr -

-

i'm trying change content of href using jquery. i've found number of answers on site, , trying use 1 implement it:

how change href hyperlink using jquery

i have wrapped in if statement this: 

if(window.location.href == "http://test.com/home.aspx"){      $("a[href='https://www.surveymonkey.com/s/tester123']").attr('href', 'https://www.surveymonkey.com/s/tester234'); }

i've put console logs in place , show line of code being reached, , this: 

$("a[href='https://www.surveymonkey.com/s/tester123']")

is returning correct link. href value never replaced when check page source.

i'm using http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js?build=7111092

i'm bit stuck on how debug issue is, can spot it? stupid mistake!

--edit--

i have checked using inspect element , it's not been replaced unfortunately.

also @vohuman , @roxxypoxxy info on not being able see change unless hovered on it. stupidly expecting work find/replace!

i think jquery version issue. using jquery 1.5. in jquery docs have mentioned this

before jquery 1.6, .attr() method took property values account when retrieving attributes, cause inconsistent behavior.

source https://api.jquery.com/attr/

so try use higher jquery version or use .prop() instead of .attr()

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...
