Working with ColorPicker

You can manipulate a ColorPicker control by using methods of the object returned by the getItem() method.

For example, you can get the value of the control:

var value = form.getItem("colorpicker_id").getValue();

List of the control methods:

clear() - clears a value of a ColorPicker control
clearValidate() - clears validation of a ColorPicker control
disable() - disables a ColorPicker control on a page
enable() - enables a disabled ColorPicker control
getValue(): boolean - returns the current boolean value of a ColorPicker control
getWidget(): object - returns the dhtmlxColorPicker widget attached to a ColorPicker control
isDisabled(): boolean - checks whether a ColorPicker control is disabled
setValue(value: string) - sets the value as a string (in the Hex format) for a ColorPicker control
validate(): boolean - validates a ColorPicker control. Returns the result of validation: true, if a control is valid, otherwise - false

Working with the widget of ColorPicker control

There is a possibility to use methods of dhtmlxColorPicker via the getWidget() method of a ColorPicker control.

For example, you can set focus on the specified value in the control. To do this, you need to get the widget attached to the ColorPicker control and then use the setFocus() method of this widget.

var colorpicker = form.getItem("colorpicker_id").getWidget();  // -> ColorPicker
colorpicker.setFocus("#BDF0E9"); // sets focus on the "#BDF0E9" color
