I am trying to clear the color from a color picker using javascript, but am not having any luck. I resorted to hard coding the colorpicker name:

function ClearBGColor(chk)
{
if (chk.checked)
{
var ctl = document.getElementById('ctl00_contentRight_DisplayText1_txtdataInfo_pickBackgroundColor');
ctl.clear();
}
}

But I get an 'Object dosen't support this method' when it calls the clear function.
How do I call colorpicker methods in javascript from a javascript function not associated with the colorpicker?

Thanks

Thank you, but now how do I get the textbox background to clear out as well? I tried both clear and setValue, but the textbox area still stays the same color. I put in an alert at the bottom of my routine and getValue returns blank, so I now the value is set correctly.
I need to set the popup selected box to clear also, so if the user opens the popup it is clear.
Basically I need everything to display based on the value I set the colorpicker to in javascript.
I'll be doing the same thing with White and Black to give the use a quick way to choose between White, Black or Transparent.
