Товарищи, помогите, пожалуйста составить правильный шаблон регулярного выражения. Есть вот такой кусок текста:

</script>
</head>
<body>
<div class="content">
<h1>System crashed</h1>
<h2>Please try to visit us later - we're working on the problem</h2>
<a href="javascript:void(0)" onclick="toggleDetails(); return false;">Show details</a>
<div id="detailsContainer" style="display: none;">
org.apache.jasper.JasperException: Unable to compile class for JSP:

1: <%
2: //Please don't remove this page!
3: TestError e = new TestError();
4: %>

Необходимо выдернуть содержимое "detailsContainer". Вот что у меня получилось:

/\<div id=\"detailsContainer\".+\>(.*)\<\/div\>/g

По такому шаблону ничего не найдено. Подскажите, где я не прав. Спасибо.

Answer 1

Обязательно это делать с помощью регулярных выражений?

let div = document.getElementById('detailsContainer');
let res = div.innerHTML;

Такой способ не подходит?

В случае, если нужно именно регулярное выражение, то у меня сработал следующий вариант:

let str = '<div id="detailsContainer" style="display: none;">test</div>';
let reg = /<div id="detailsContainer" (.*)>(.*)<\/div>/;
console.log(str.match(reg)[2]);

В консоль выводится слово "test"
