Is it possible to check if a specific object is hidden or visible with JavaScript?

I know how to show or hide an object with JavaScript but I need to verify if an object is hidden or visible using JavaScript.

You can do the following...

cp.D.myObjectNamec.visible

In the browser console this will return a 1 if the object is visible and a 0 if the object is hidden.

Simply replace the myObjectName in the code above with the name of the object you wish to query.

Do not remove the c at the end.

You could also assign the above code to a variable and apply this to a button and then provide a smartShape to display the value of the variable and then do stuff based on that value.

Hope that helps.

Thanks a lot! That solved my problem.

As I needed the object name to be variable I did that using eval(). See example bellow, just for the records and if someone eventually need it:

var nS = cpInfoCurrentSlideLabel;
var txtB = "cp.D." + nS + "_button_namec.visible";
var txtM = "cp.D." + nS + "_msgc.visible";

var vButton = eval(txtB);
var vMessage = eval(txtM);

alert("Button visibility: " + vButton + " | Message visibility: " + vMessage);

I would add that somtimes Captivate will return true or false instead of 1 or 0, so you would need to chack for that.

It is really bad form to use eval, there are many ways to get around uing that method. window [] syntax is much better.

In your code above, the slide label is in a variable, but not the button name.
