javascript - Format string with line breaks into paragraphs -

-

i'm using contentful cms manage content , pulling in content api.

the content pulled in json object. 1 of keys in object main block of text entry pulling. string has no actual code in it, have line breaks. in chrome console these appear small return arrow. part of object looks this:

var article = {   name: "some name here",   content: "lorem ipsum dolor sit amet, consectetur adipiscing elit. sed lobortis libero lacus. morbi non elit purus. mauris eu dictum urna. nam vulputate venenatis diam nec feugiat. praesent dapibus viverra ullamcorper. donec euismod purus vitae risus dignissim, id pulvinar enim tristique. donec sed justo justo. sed et ornare lacus. lorem ipsum dolor sit amet, consectetur adipiscing elit. sed lobortis libero lacus. morbi non elit purus. mauris eu dictum urna. nam vulputate venenatis diam nec feugiat. praesent dapibus viverra ullamcorper. donec euismod purus vitae risus dignissim, id pulvinar enim tristique. donec sed justo justo. sed et ornare lacus. lorem ipsum dolor sit amet, consectetur adipiscing elit. sed lobortis libero lacus. morbi non elit purus. mauris eu dictum urna. nam vulputate venenatis diam nec feugiat. praesent dapibus viverra ullamcorper. donec euismod purus vitae risus dignissim, id pulvinar enim tristique. donec sed justo justo. sed et ornare lacus." }

notice line breaks within content field. how take article.content , format these paragraphs actual <p> tags? want render html so:

<p>lorem ipsum dolor sit amet, consectetur adipiscing elit. sed lobortis libero lacus. morbi non elit purus. mauris eu dictum urna. nam vulputate venenatis diam nec feugiat. praesent dapibus viverra ullamcorper. donec euismod purus vitae risus dignissim, id pulvinar enim tristique. donec sed justo justo. sed et ornare lacus.</p> <p>lorem ipsum dolor sit amet, consectetur adipiscing elit. sed lobortis libero lacus. morbi non elit purus. mauris eu dictum urna. nam vulputate venenatis diam nec feugiat. praesent dapibus viverra ullamcorper. donec euismod purus vitae risus dignissim, id pulvinar enim tristique. donec sed justo justo. sed et ornare lacus.</p> <p>lorem ipsum dolor sit amet, consectetur adipiscing elit. sed lobortis libero lacus. morbi non elit purus. mauris eu dictum urna. nam vulputate venenatis diam nec feugiat. praesent dapibus viverra ullamcorper. donec euismod purus vitae risus dignissim, id pulvinar enim tristique. donec sed justo justo. sed et ornare lacus.</p>

the easiest way split on \n , rejoin on </p><p>:

  1. split: split takes string , breaks apart string, example if have string 1,2,3,4 , split on ,, end javascript array [1, 2, 3, 4].
  2. rejoin: join takes javascript array, , glues string using string glue. example, if take array have [1, 2, 3, 4] , join on #, end string 1#2#3#4.

so following these steps swapping out , \n , # </p><p> able make string 1</p><p>2</p><p>3</p><p>4. almost right, notice don't have starting <p> or ending </p> throw on beginning , end of string:

var paragraphs = '<p>' + article.content.split("\n").join('</p><p>') + '</p>';

check out this jsbin example. top box input, bottom output.

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...
