How to change innerHtml element in Dart SDK 0.7.1

Question

I am using dart-message https://github.com/mkozhukh/dart-message . It has a function ...

MessageBox(String text, String header, String css){ _box = new DivElement(); ... _box.onClick.listen(_clickHandler); if (header != null) html.write("<div class='dhtmlx_popup_title'>$header</div>"); html.write("<div class='dhtmlx_popup_text'><span>$text</span></div>"); html.write("<div class='dhtmlx_popup_controls'>"); } String addButton(String text, String result){ if (html != null){ html.write("<div class='dhtmlx_popup_button' result='$result' ><div>$text</div></div>"); } else throw new Exception(".addButton must be used before .show"); } _clickHandler(Event event){ String result = event.target.attributes["result"]; if (result == null) result = event.target.parent.attributes["result"]; hide(result); //<=== ERROR result alway return null } 

AND

 Future<String> show(){ if (html != null){ //finalize html initialization html.write("</div>"); _box.innerHtml = html.toString(); //<===== ERROR after line : Removing disallowed attribute <DIV result="ok"> html = null; } ... } 

...

How to change this code to SDK 0.7.1. Thank you very much.

Answer 1

I changed the code

 _box.innerHtml = html.toString(); 

==>

 _box.setInnerHtml(html.toString(), treeSanitizer : new NullTreeSanitizer()); 

and it works.
