Highlight text in multiple content divs from input

问题

I have this search and highlight function which works fine until I try to search across multiple content divs. What would be the best route to take to get to a solution as I don't want to duplicate the function for each content div.

I was thinking of possibly using a for each function...?

Thank you in advance!

Javascript:

//highlight search terms in content
var searchCnt = 0;

var option = {
  color: "black",
  background: "lightskyblue",
  bold: false,
  class: "high",
  ignoreCase: true,
  wholeWord: false
};

var textContent = $(".searchtext")
  .html();
// searchCnt = $(".searchtext-One").highlight($("#searchInput").val(), option);
// $("#matcheCnt").text(searchCnt);

$("#searchInput").keyup(function() {
  $(".searchtext")
    .html(textContent);
  $("#searchInput").val(this.value);
  if (this.value == "") return;
  searchCnt = $(".searchtext")
    .highlight(this.value, option);
  $("#matcheCnt").text(searchCnt);
});

This is the script I found to work:

// highlight search terms in content
var searchCnt = 0;

var option = {
  color: "black",
  background: "lightskyblue",
  bold: false,
  ignoreCase: true
  wholeWord: true
};

$("#searchInput").keyup(function() {
  var searchVal = $(this).val();
  if (!searchVal || searchVal === "") {
    return;
  } else {
    $(".searchtext").each(function() {
      $(this).highlight(searchVal, option);
    });
  }
});
