Trying to get Hex/RGB value of a color preview swatch, please help!

[royd]

Hi everyone

In configuration page some colors are customizable. 

• When clicked on any of the input fields, a color chooser pops up.
• Selecting a color populates the field with the hex value.
• The preview swatch updates to the selected color.

I am trying to access the hex value of the preview color. After some reading, this is what I came up with:

(I have noticed that swatch value shows up as Hex in Chrome but as RGB in IE!)

  var colorPrimary = page.QuerySelector(".evo-colorind");
  var style = page.contentDocument.defaultView.getComputedStyle(colorPrimary, "");
  Log.Message(style.background-color);

I am getting JavaScript runtime error 0x80020101 at 'style' var. Any help deeply appreciated.

I am surprised that even the Smartbear support team is surprisingly quiet! Does this mean there is no way TestComplete can do this!!?

Actually, I think the difference is beyond even just whether or not it shows as RGB versus Hex...  I have a checkpoint set up that does something similar.... but the caveat that I have is that it will work with IE only.  I think the contentDocument property/object or some of the methods and properties of it are only available in IE.  That would be where I'd start, to put a breakpoint on that line and do some investigation as to why JavaScript is burping there...

Thanks Robert!

You are always there when I need help!  I almost gave up hope. I will give it a try tomorrow and let you know.

Hi Robert,

As you suggested, I am using IE 11. Now I am getting runtime error:

            JavaScript runtime error.
      TypeError: Cannot read property 'color' of null

If you take a look at the above screenshot, the style (color) in named 'backgroud-color'. I am using the following to Log the color:

var style = page.contentDocument.defaultView.getComputedStyle(colorPrimary, "");
Log.Message(style.background-color);

I am not quite sure if I should be using 
Log.Message(style.background-color);

or

Log.Message(style.color);

Either way, I am getting the same error. 

Thank you.

In the code that I'm using, I get the element from the page in IE... then I get the "currentStyle.backgroundColor" property.  I think that's better than the getComputedStyle method.  See if that works better for you.

Thank you. I will give it a try.

I used:

var style = page.contentDocument.defaultView.currentStyle.backgroundColor(colorPrimary, "")

as you suggested.

I am getting:

               JavaScript runtime error.
              TypeError: Cannot read property 'backgroundColor' of undefined

backgroundColor is not a method, it's the actual property.   So, just compare that property to the desired value.

Hi Robert

Thank you for the clarification.
