javascript - How to synchronize two text areas within separate iframes? -

-

i have 2 iframes, both of contain form text area.

my goal synchronize 2 text areas, user types in 1 reproduced in other. how can across 2 (or more) separate iframes?

main document:

<script> $("iframe").ready(function(){     $(".editor").keyup(function(){         $(".editor").val($(this).val());     }); }); </script>  <iframe src="/editor.php?mode=post&f=1" class="iframe-editor"></iframe> <iframe src="/editor.php?mode=post&f=2" class="iframe-editor"></iframe>

content of iframes:

<fieldset class="fields1">      <textarea name="message" id="message" class="editor">{message}</textarea>  </fieldset>

as of now, jquery script works if text areas placed in main document.

the way have set doesn't work because ".editor" belongs dom. however, can access dom using "contentwindow" property of iframe element.

you can pass myiframe.contentwindow.document context jquery, jquery searches there.

http://jsfiddle.net/cbv0xfq2/

$('.iframe-editor').each(function() {   var frame = this;    $(frame.contentwindow.document.body).on('input', '.editor', function() {     var textarea = $(this);     $(".iframe-editor").not(frame).each(function() {       $('.editor', this.contentwindow.document).val(textarea.val());     });   }); })

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...
