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.
