Hi,
I have a reactive form and inside the class, I have a bunch of custom
(group)validators.
>From within the validator function, I need to set a variable that is
defined in the class, but I get an "undefined is not an object" error.
Since all the other functions work just fine, I presume it has something to
do with the AbstractControl.
Here's an example of the code:
errorVar: boolean = false
function(c: AbstractControl): {[key: string]: string } | null {
// validation if 'test' is true or not goes here
if(test) {
let errorMessageText: "test"
return {'errorText': errorMessageText};
}return null;}
This fails:
errorVar: boolean = false
function(c: AbstractControl): { [key: string]: string } | null {
// validation if 'test' is true or not goes here
if (test) {
this.errorVar = true;
let errorMessageText:
return { 'errorText': errorMessageText };
}
this.errorVar = false;
return null;
}
So my idea was to maybe set the variable errorVar during the return, but I
can't seem to be able to append it to function(c: AbstractControl): { [key:
string]: string } | null {
Anybody got some ideas?
Thanks, Phil
