Find text by search and highlight current result only

Trying to highlight current/single text only, like browser "Control-F" keyboard command search. find next/new text when search again is good. But it's highlight all result, trying to highlight only Current result/text.

JS below:

$('body').on('keydown', '#searchfor', function(e) {
if (e.which === 32 && e.target.selectionStart === 0) {
return false;
}
});

//Create some vars to later check for:
//['text you are searching', 'number of highlights','actual highlight']
var searching,
limitsearch,
countsearch;

$('button#search').click(function() {
var searchedText = $('#searchfor').val();
var page = $('#ray-all_text');

//Now check if the text on input is valid
if (searchedText != "") {
//If the actual text on the input is different from the prev search
if(searching != searchedText) {
page.find('span').contents().unwrap();
var pageText = page.html();
var theRegEx = new RegExp("(" + searchedText + ")", "igm");
var newHtml = pageText.replace(theRegEx, "<span>$1</span>");
page.html(newHtml);
//Set your variables to the actual search
searching = searchedText;
limitsearch = page.find('span').length;
countsearch=0;
} else {
//If it's the same of the prev search then move to next item instead of repaint html
countsearch<limitsearch-1 ? countsearch++ : countsearch=0;
console.log(countsearch+'---'+limitsearch)
}
//Go to target search
$('body').animate({
scrollTop: $("#ray-all_text span").eq(countsearch).offset().top - 50},
200);
} else {
alert('empty search')
}
});


HTML:

<div class="ray-search">
<div class="field" id="ray-search-form">
<input type="text" id="searchfor" placeholder="what are you searching for?" />
<button type="button" id="search">Press to Find!</button>
</div>
</div>

<article id="ray-all_text">

There any solution?

Answer

You can add a class to the current target. The lines from your code I change:

var actual = $("#ray-all_text span").eq(countsearch);
$('.active').removeClass('active');
actual.addClass('active');
$('body').animate({
   scrollTop: actual.offset().top - 50}, 
200);

And on the CSS:

#ray-all_text span.active {
    background-color:yellow;
}
