insert inside the <body> this <div>
<div id="yourParam" style="visibility: hidden;"><SCRIPT
LANGUAGE="JAVASCRIPT"
TYPE="TEXT/JAVASCRIPT">document.write(anything_you_want);</SCRIPT></div>
and inside the onModuleLoad retrieve the DIV in this way:
String param=DOM.getInnerHTML(DOM.getElementById("yourParam"));
int indexOfScriptEnd = param.toUpperCase().indexOf("</SCRIPT>");
if (indexOfScriptEnd!=-1) {
choosedProduct =
param.substring(indexOfScriptEnd+"</SCRIPT>".length()).trim();
}
The indexOf is needed to have compatibility with all browser 'cause browsers
different from IE
gives back also the entire SCRIPT.
You can also use inside the div some Hidden Inputs and so retrieve as many
params as
you want.
Hope it helps, Patrizio
PS But there are other solutions based on GWT, this is my solution and you
can bet that isn't the smartest ;)
