Привет У меня есть фильтр, который заменяет \n на \n\n, когда я использую этот фильтр для своих json-данных. Я получаю сообщение об ошибке. Can't interpolate: {{ post.description|nlToArray }} TypeError: Cannot read property 'replace' of undefined
Мой фильтр
sampleApp.filter('nlToArray', function() {
return function(text) {
return text.replace(/\n/g, '/\n\n');
};
});

Чтобы быть более понятным, описание в json выглядит так
morphing into a tech oasis.\r\nThe militarys massive relocation of its prestigious technology units.\r\nBeersheba has all of the ingredients of a vibrant security technology ecosystem, \r\n"All in all, projections are that 20,000-30,000 \r\nThe commercial sector has teamed up cyber attacks.
Каким может быть возможное решение... Спасибо заранее
Сделать код нулевым, заменив
sampleApp.filter('nlToArray', function() {
return function(text) {
return text.replace(/\n/g, '/\n\n');
};
});
с
sampleApp.filter('nlToArray', function() {
return function(text) {
if (text)
return text.replace(/\n/g, '/\n\n');
else
return text;
};
});
