javascript - How to get the height and width of an iframe -

-

how height , width of iframe, executing script outside iframe?

i want find dimensions.

javascript solutions welcomed.

using jquery: 

$('iframe').height(); $('iframe').width();

edit elaborating on quick , dirty answer above. .height() , .width() give element's height , width without padding, border or margin.

if want include padding , border need use .innerheight() , .innerwidth(). example below:

$('iframe').innerheight(); $('iframe').innerwidth();

if want include padding , border , margin need use .outerheight() , .outerwidth(). example below:

$('iframe').outerheight(); $('iframe').outerwidth();

links methods above:

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...
