Output only the first word from select list value - jQuery?

jQueryWeb DevelopmentFront End Technology

Let’s say the following is our select −

<select id="firstValueDemo" onchange="showFirstValue(this)">
   <option value="John Smith">Get First Name</option>
   <option value="David Miller">Get First Name Only</option>
</select>

To get only the first word, use split() on the basis of space and can select the 0th index value.

Example

Following is the code −

 Live Demo

<!DOCTYPE html>
<html lang="en">
<head>
   <meta charset="UTF-8">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>Document</title>
</head>
<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>
<body>
   <select id="firstValueDemo" onchange="showFirstValue(this)">
   <option value="John Smith">Get First Name</option>
   <option value="David Miller">Get First Name Only</option>
   </select>
</body>
<script>
   function showFirstValue(choosenObject) {
      var allValues = choosenObject.value.split(" ");
      var firstValue = allValues[0];
      console.log("The first Name=" + firstValue);
   }
</script>
</html>
