How to get selected text on click of an element in javascript -

-

i have div [contenteditable=true] attribute. when select text , click button, want selected text. did following:

$(".btn").click(function (){    alert(window.getselection()); });

the above code not alert anything. if change .btn element img element, alert outputs selected text. can selected text on click of element

thid html code:

<li class="btn">selection </li> <div contenteditable="true">some text here</div>

when select required text , click button, ramon & adeneo explains in comment, focus lost. button command executed @ mouseupat point selection cleared. far understand, reason why code works image because unlike button image command executed @ mousedown.

my suggestion try .on('mousedown', ...) command instead of simple click command.

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...
