Client Screen Resolution

[Jez]

Hi,

I'm trying to get the users IE screen resolution at run-time, so I can decide in fpl on a course of action to take regarding presentation.

Is there an ebase in-built way of detecting the client IE screen resolution? If not, I can determine the screen height & width using javascript by using;

screen.width and screen.height

If there isn't an ebase in-built function for getting the screen height & width (in pixels) is there a way of passing this info into an ebase filed if I call the javascript from the form properties; HTML++ section?

Hope this makes sense. Thanks,
Jez

Use JavaScript to set the uservar formfields. Trigger form submit with javascript function.

Hi,

Thanks for your reply Joost.

My javascript knowledge is unfortunately fairly poor, but the instructions linked to above seem to be for passing a variable into the ebase $USERVAR1 variable, when a button is clicked on a non-ebase section of a form (e.g. a JSP). Have I understood this correctly?

I need to automatiacaly set the variable when the form loads, rather than when a user clicks a button. I do have a LEFT and a TOP JSP on my form, but if I'm not actioning the set when a button is pressed, do the JSP's need to be involved in this process?

If I put the following java script into the HTML++ section of the ebase form I call, I get an alert pop up showing me my screen width as anticipated;

Code: Select all

<script>
  alert&#40;screen.width&#41;;
</script>

However, if I try setting the $USERVAR1 field from here (as follows)

Code: Select all

<script>
  setFieldValueExternal&#40;"$USERVAR1","test"&#41;;
</script>

I get a javascript error when the page loads;
'documents.RW.elements' is null or not an object

Does anyone have any advice?

I need to automatiacaly set the variable when the form loads, rather than when a user clicks a button.

This is possible with the javascript functions. No user interaction needed.

'documents.RW.elements' is null or not an object

Ah... ok. use bottom.jsp. Following code should do the trick.

Code: Select all

<script>
  setFieldValueExternal&#40;"$USERVAR1","test"&#41;;
  externalSubmit&#40;&#41;;
</script>
