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

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">

<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>
