Re: How-to display a Javascript-Widget (e.g. from tripadvisor) in an GWT HTML Widget?
I found something about "Script Injection" and tried the following code to
add the script in my HTML page (on EntryPoint - method):
Document doc = Document.get();
ScriptElement script = doc.createScriptElement();
script.setSrc("
http://www.jscache.com/wejs?wtype=cdswritereviewlg&uniq=303&locationId=206597&lang=en_AU&border=true
");
script.setType("text/javascript");
script.setLang("javascript");
doc.getBody().appendChild(script);
and added the other code as String in an HTML-Widget.
But there is the same issue. Only the text:
"Review Grand Hotel
Wien
"
appears!

It's a bit easier with GWT's ScriptInjector (just don't forget
setWindow(TOP_WINDOW)).

That script uses document.write() so it cannot be script-inserted. Try
injecting the script it document.write()s though, it looks like it should
be OK (just wouldn't benefit from "jscache.com", whatever it is)

Re: How-to display a Javascript-Widget (e.g. from tripadvisor) in an GWT HTML Widget?
Thank you for your answer, but
if I enter the URL
http://www.jscache.com/wejs?wtype=cdswritereviewlg&uniq=303&locationId=206597&lang=en_AU&border=truein
browser I see the following document.write():
document.write( 'http://www.tripadvisor.com/WidgetEmbed-cdswritereviewlg?amp;uniq=303&border=true&lang=en_AU&locationId=206597";>'
);
The domain www.jscache.com is from Tripadvisor (
http://www.domainmetrics.de/domain/www.jscache.com) - maybe security reason
- I don't know but it seems mandatory?
If I interpret your answer in a correct manner, I tested both:
ScriptInjector.fromUrl("http://www.jscache.com/wejs?wtype=cdswritereviewlg&uniq=303&locationId=206597&lang=en_AU&border=true";).setWindow(ScriptInjector.TOP_WINDOW).inject();
and
ScriptInjector.fromUrl("
http://www.tripadvisor.com/WidgetEmbed-cdswritereviewlg?amp;uniq=303&border=true&lang=en_AU&locationId=206597
").setWindow(ScriptInjector.TOP_WINDOW).inject();
but it is not working and only the text appears as described above.
If I try to enter the document.write()s script (http://www.tripadvisor.com.au/WidgetEmbed-cdswritereviewlg?uniq=303&locationId=206597&border=true&lang=en_AU";>)
in the online-editor:
http://www.w3schools.com/html/tryit.asp?filename=tryhtml_intro it is also
now not working and I also see only the text.
So it seems, that the document.write() is mandatory.
How can I solve this problem or do you know a better way to integrate a
Tripadisor widgets for reviews of hotels, created with this site:
http://www.tripadvisor.de/Widgets ?
