What is the difference between IHeaderResponse renderJavascript(...),
renderOnBeforeUnloadJavascript(...) and renderOnLoadJavascript(...) methods?
I would like to add different chunks of JavaScript to the head based on the
requirements of my Page. Can I do this?
public void renderHead(IHeaderResponse response) {
response.renderJavascript("JavaScript 1 Blah Blah");
response.renderJavascript("JavaScript 2 Blah Blah");
response.renderJavascript("JavaScript 3 Blah Blah");
...
}
Will each one of the renderJavascript(...) overwrite the previous one or
will they be added together?
