У меня есть следующее приложение, которое ищет слова, которые вы вводите, разделенные одним пробелом. Вы можете ввести каждое слово и нажать клавишу ввода, и оно выделит все ваши слова на странице. Единственная проблема заключается в том, что он не экранирует содержимое HTML, поэтому, если вы введете какие-либо символы, такие как <> class = "" strong bold и т. Д. ..., они сохранят их в переменную txt, а затем начнут умножать HTML каждый цикл для каждого слова во входных данных. , Мне не нужно, чтобы ошибка была исправлена, и я понимаю, что это как-то связано с моей переменной term и txt. Но, возможно, ты видишь то, чего не вижу я.
var highlightRe = /<span class="highlight">(.*?)<\/span>/g,
highlightHtml = '<span class="highlight">$1</span>';
$(function() {
/////////////////////////when search value changes
$('#search').change(function() {
////////////////////////////grab #search value and split it into array
var str = document.getElementById('search').value;
var res = str.split(" ");
//////////////////replace all html text with
var txt = $('#txt').html().replace(highlightRe,'$1');
///////// x = index of array res (array of key words to search in txt)
var x=0;
//////////////check if each word exists in txt and highlight it
for (x in res) {
var term = res[x];
////////////////////////////if I sanitize term from HTML content here. Then there is no bugs but then I cannot use the letters included inside HTML tags
if(term !== '') {
txt = txt.replace(new RegExp('(' + term + ')', 'gi'), highlightHtml);
}
}
$('#txt').html(txt);
});
});
.highlight {
background-color: yellow;
