SHOW / HIDE RULERS script

Question

hi iam only starting with scripting
i want a script that will hide rulers IF THEY ARE VISIBLE
if they are already hidden (CTRL+R) it should just skip over...
i have this simple script:
app.panels.everyItem().visible = false; //hides all palettes
app.activeWindow.zoomPercentage= 131 //sets window zoom to 131% which is around 1:1 zoom with real size ruler in my screen resolution
app.activeWindow.maximize() //maximize window to get a full screen presentation view
app.activeWindow.maximize() //again maximizes in case the last command just restored the window instead of fully maximizing...
its not perfect at all but does the job of switching into 1:1 real size zoom and displaying full screen presentation of the page...
now i need to add a line that will also hide rulers if they are visible but if they happen to be hiden already at that time it should do nothing...
i managed to come up with something like this:
var myMenuAction = app.menuActions.item("$ID/Hide rulers");
myMenuAction.invoke();
which works only ONE WAY when the rulers are visible but throws an error when the rulers are already hidden... thats because the menu item is switchable (HIDE RULERS / SHOW RULERS)

Answer 1

LOL MAN thats hillarious... nice job
as if i wasn't just babbling about it whole day...
iam sorry to say it becuase i respect guys like Olav but the biggest obstacle in learning JS in CS3 is its poor object model documentation... and tools like ExtendScript2 doesnt help a bit... when i type "Rulers" in find field of Object Model Viewer it shows two misserable entries...
only when i specifically (thanks to you) KNOW IAM LOKING for "showRulers" entry ExtendScript2 will find the term for me... but thats ridicullous i dont need a find function which doesnt look around the corner...
NEVERMIND THANKS FOR YOUR TIP "showRulers -- bool -- r/w -- If true, displays the horizontal and vertical rulers." IS WHAT I WAS HOPELESSLY LOKING FOR...
