if (isBlank(control.value) || (isString(control.value) && control.value.trim() === '')) {
return false;
}
return true;
}示例2: transform
transform(value) {
if (isBlank(value)) return value;
if (!isString(value)) {
throw new InvalidPipeArgumentException(JsonPointerEscapePipe, value);
}
return JsonPointer.escape(value);
}示例3: transform
transform(value:number):any {
if (isNumber(value)) {
return new Date(value * 1000);

}
}
}示例4: _normalizeOptions
