Two questions: Event on a Date Picker and Read Only on a full page?

Question

Hello,
I make use of this very informative board to develop an application but i have been unable to find info on these two topics. Sorry if it has been already discussed extensively.
Using HTMLDB 2.2 for now.
=>First question:
I have a date picker item with an event
onChange="resaStatusChange();"
in the HTML Form Element Attribute field.
The event is triggerring if i put a new data in the field but does not trigger if i use the picker.
Is it a standart behaviour? Is there a way to trigger the event when new data is provided through the date picker?
=> Second question:
One page in my application has to be used either to only display information or as a mixed displaying/entering data sheet.
When the context is appropriate to use the page as a simple display (testing both global authorization and data to be displayed), is there a way to put a read only attribute on the full page instead of putting the read only conditions through each and every item of the page?
Sorry if the questions are not clear and apologize for what should be newbie questions.
Any link or info will be appreciated.
Regards,
Daniel Gureghian

Hi Daniel,
I'm not sure about your first question, but I can hopefully give you a helpfull answer for your second one.
I'm handling it this way:
var elInput = document.getElementsByTagName('input');
var elTextArea = document.getElementsByTagName('textarea');
var elSelect = document.getElementsByTagName('select');
for (i = 0; i < elInput.length; i++)
  setReadOnly(elInput, true);
for (i = 0; i < elTextArea.length; i++)
setReadOnly(elTextArea[i], true);
for (i = 0; i < elSelect.length; i++)
setReadOnly(elSelect[i], true);
function setReadOnly(pThis, pRead)
     if (pThis && pRead)
          pThis.disabled = pRead;
          pThis.style.emptyCells = "show";
          pThis.style.color = "black";
          pThis.style.backgroundColor = "#DDDDDD";
     else if (pThis && !pRead)
          pThis.disabled = pRead;
          pThis.style.emptyCells = "show";
          pThis.style.color = "black";
          pThis.style.backgroundColor = "#FFFFFF";
I never used it on a whole page, only for regions. So maybe you have to make some changes.
