Vaadin Label not working

Question

In Vaadin Label , I set a html content as String . That html is consisted of a html form and javascript+jquery related stuff for form submission and other processing.

Even though the form is correctly loaded to the UI , the javascript stuff is not working .

So what can be the reason ? . Is there any otherway to do this ?

`the javascript stuff is not working` what happens? Are some errors shown in the browser console? — André Schild, Nov 04 '15 at 11:25
No . even the simple alerts are not working , couldn't figure-out the reason — chathura, Nov 05 '15 at 04:33
Have you looked at the generated source sent to the browser? I might think that the vaadin framework prevents such JS injections for security reasons... — André Schild, Nov 05 '15 at 07:29

To execute JavaScript from your server-side Vaadin code you should API provided by the JavaScript class, e.g.:

com.vaadin.ui.JavaScript.execute("alert('Hello World');");

But you must be very careful when you using this API, so I recommend this only for very simple JavaScript. For more complex cases you must create your own widget or extension by using GWT or Javascript on the client side.
