سؤال


Let’s the following is our input type, wherein the user will search −

<input type="text" class="txtInput" id="searchTheKey" placeholder="Enter the keywords to search.....">

Now, use hide() and show() to display only relevant search and hide rest. For example, on typing “Ja”, related keywords like “Java” and “JavaScript” should be visible because it begins with “Ja”.

Example

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initialscale=1.0">
<title>Document</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<label>
Enter the keyword..
<input type="text" class="txtInput" id="searchTheKey" placeholder="Enter the keywords to search.....">
</label>
<ul id="matchKey">
<li id="subjectName">JavaScript</li>
<li id="teacherName"><a href="#">John Smith</a></li>
<li id="subjectName">Java</li>
<li id="teacherName"><a href="#">David Miller</a</li>
<li id="subjectName">MongoDB</li>
<li id="teacherName"><a href="#">Carol Taylor</a></li>
</ul>
<script>
   $("#searchTheKey").on('keyup', function(){
      var value = $(this).val().toLowerCase();
      $("#matchKey li").each(function () {
         if ($(this).text().toLowerCase().search(value) > -1) {
            $(this).show();
            $(this).prev('.subjectName').last().show();
         } else {
            $(this).hide();
         }
      });
   })
</script>
</body>
</html>
