Целевые элементы по id Использование jQuery

Description

Вы также можете настраивать элементы по их атрибутам id. Сначала target3 элемент button с target3 с помощью селектора $("#target3") . Обратите внимание, что, как и в объявлениях CSS, вы вводите # перед именем id. Затем используйте .addClass() jQuery для добавления классов animated и fadeOut . Вот как вы делаете элемент button с id target6 исчезающим: $("#target6").addClass("animated fadeOut") .

  - text: Select the <code>button</code> element with the <code>id</code> of <code>target3</code> and use the jQuery <code>addClass&#40&#41</code> function to give it the class of <code>animated</code>.
    testString: assert($("#target3").hasClass("animated"));
  - text: Target the element with the id <code>target3</code> and use the jQuery <code>addClass&#40&#41</code> function to give it the class <code>fadeOut</code>.
    testString: assert(($("#target3").hasClass("fadeOut") || $("#target3").hasClass("fadeout"))  && code.match(/\$\(\s*.#target3.\s*\)/g));
