validate()
validates a CheckboxGroup control
validate(silent?: boolean): boolean;
Parameters:
silent: boolean
- optional, if true - the method will return the result of validation without calling validation events and without modifying the control visually
Returns:
true
, if a control is valid; otherwise, false
.
Example
form.getItem("CheckboxGroup").validate(true); // -> true/false
When calling without the silent parameter or setting it to false, the method invokes the beforeValidate and afterValidate events and visually modifies the control.
form.getItem("CheckboxGroup").validate(); // -> true/false
form.getItem("CheckboxGroup").validate(false); // -> true/false
Change log:
The silent parameter is added in v7.0
