JQuery селектор, чтобы игнорировать элемент? - PullRequest

/ 30 июня 2018

Я извлекаю содержимое страницы статьи.

Один селектор, "entry": $('div.content__article-body').html().trim() получает основной текст статьи. В основном это текстовые абзацы с их <p> и тегами заголовка, что я и хочу Тем не менее, он также получает элемент, который мне не нужен, а именно <aside>. Как я могу убедиться, что <aside> НЕ включено в полученный текст?

Здесь я читал темы о "не". Я пробовал такие вещи, как ...

$('div.content__article-body').not('aside').html().trim()

$('div.content__article-body').html().not('aside').trim()

$('div.content__article-body:not(aside)').html().trim() или $('div.content__article-body:not('aside')').html().trim() - не уверен.

Но, похоже, ничего из этого не работает. Я неправильно понимаю, как использовать "не"?

Обновление : Выдержка ниже (aside - это, по сути, раздел в статье) ...

<h2>1. Know your predicament</h2>
<p>It would be nice to say the switch to free comes either out of benevolence or out of a market opportunity. The reality is, operators invariably flick the switch under external pressure of a poor business outlook – no amount of dressing up as a “bold relaunch” can change that.</p>
<p>NME’s circulation was falling by <a href="https://www.theguardian.com/media/2014/feb/13/nme-relaunch-sales-slide-ipc-media" data-link-name="in body link" class="u-underline">around a fifth annually</a>. The Evening Standard was frustrated to find itself far behind national dailies on ad planners’ schedules, locking it out of big brand bucks, according to someone familiar with the strategy to switch.</p>
<p>The Village Voice dropped its cover charge in 1996 after being eaten into by rival New York Press being given away in green sidewalk boxes, while Hong Kong’s Standard newspaper was forced to act when the government removed a decree that listed companies must buy classified ads in newspapers. But the key – as anyone who has heard the “<a href="https://en.wikipedia.org/wiki/Boiling_frog" rel="nofollow" data-link-name="in body link" class="u-underline">boiling frog</a>” allegory will know – is to recognise when it is your time to change tack.</p>

Вы можете попробовать что-то вроде этого:

var e = $('.box').html();
console.log(e);

var subStr = e.match("<aside>(.*?)</aside>");
var r = e.replace(subStr[0], "");

console.log(r);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="box">
  Some text here
  <p>More text here</p>
  <aside>this is an <span>aside</span></aside>
</div>

Или вы создаете другой элемент, затем удаляете сторонний узел:

var e = $('.box').html();
var newE = $('<div>'+e+'</div>');
newE.find('aside').remove();
console.log(newE.html());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="box">
  Some text here
  <p>More text here</p>
  <aside>this is an <span>aside</span></aside>
</div>

С помощью метода .not() сделайте так, разверните селектор до div.content__article-body > *, чтобы он нацелился на братьев и сестер div, а затем переберите результат.

Использование дочернего селектора > позволяет исключить любые элементы внутри aside, хотя это также повлияет и на другие элементы, и чтобы вернуть их потомков в вывод, используйте .outerHTML.

Фрагмент стека

$('div.content__article-body > *').not('aside').each( function( index, value ) {
  console.log( value.outerHTML );
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="content__article-body">

    <p>some paragraph <span>some span</span></p>

    <div>some div</div>

    <aside>an aside <div>some div in aside</div></aside>

</div>

И с селектором :not().

Попробуйте это.

$ ("div.content_article-body *: not (в сторону)");
