RootPanel.get().add(this);
HTML html = new HTML();
this.add(html);
String sHTML="<input type=button onclick=" + "go2()" + "
value='Click Me'><BR>";
String sScript="<SCRIPT DEFER>";
sScript = sScript + "function go2(){ alert('Hello from inserted
script.') }";
sScript = sScript + "</SCRIPT" + ">";
html.setHTML(sHTML+sScript);
This code works is IE also.
As per msdn http://msdn.microsoft.com/en-us/library/ms533897(VS.85).aspx
*"When using innerHTML** **to insert script, you must include the DEFER
attribute in the script element."*
