Quickly Search Through Text Within The Document - jQuery Finder

Finder is a jQuery live search plugin which enables the user to quickly search through the text within the document similar to the CTRL+F features in the Chrome browser.

Features:

• Click the 'Search' button to open the search bar.
• Click the 'Up' and 'Down' buttons to cycle through all of the matched text.
• Provides a counter that shows the number of results.
• Highlights the matched text. Requires jQuery highlight plugin.
• Auto scrolls through the webpage when cycling through matched text. Requires jQuery Scrollto plugin.

How to use it:

1. Include the jQuery Finder plugin and other required JavaScript resources on the webpage.

<script src="https://code.jquery.com/jquery-3.3.1.min.js"
        integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8="
        crossorigin="anonymous"
></script>
<script src="/path/to/jquery.highlight.js"></script>
<script src="/path/to/jquery.scrollto.js"></script>
<script src="/path/to/jquery.finder.js"></script>

2. Create a trigger button to toggle the search bar.

<button class="finder-activator" data-finder-activator>
  Search
</button>

3. Wrap the content into a container with the 'data-finder-content' attribute.

<div class="content" data-finder-content>
  content here
</div>

4. Wrap the search bar and main content into a container with the 'data-finder-wrapper' attribute.

<div class="app" data-finder-wrapper data-finder-scroll-offset="175">
  <button class="finder-activator" data-finder-activator>
    Search</button>
  <div class="content" data-finder-content>
    content here
  </div>
</div>

5. Wrap the search bar and main content into a container with the 'data-finder-wrapper' attribute.

<div class="app" data-finder-wrapper data-finder-scroll-offset="175">
  <button class="finder-activator" data-finder-activator>
    Search</button>
  <div class="content" data-finder-content>
    content here
  </div>
</div>

6. That's it. The example CSS to style the search bar & highlighted text.

.finder {
  position: fixed;
  top: -50px;
  right: 0;
  left: 0;
  z-index: 999;
  display: -webkit-box;
  display: -ms-flexbox;

  font-family: Arial, Helvetica, sans-serif;
  font-size: 14px;
  border-bottom: 1px solid #e5e5e5;
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.2);
  padding: 5px;
  transition: top 0.15s ease-out;
}

.finder.active {
  top: 0;
}

.finder-input {
  flex-grow: 1;
  width: 0;
  height: 40px;
  border: none;
  padding: 8px;

}

}

.btn-finder {

.btn-finder:not(:last-child) {
  margin-right: 5px;
}

.finder-count {
  display: -webkit-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  flex-direction: column;
  justify-content: center;
  color: #888;
  border-right: 1px solid #e5e5e5;
  margin-right: 5px;
  padding-right: 20px;
  white-space: nowrap;
}

.btn-finder,
