Use the jQuery val() Method
You can simply use the jQuery val() method to get the value in an input text box.
Try out the following example by entering something in the text input box and then click the "Show Value" button, it will display the result in an alert dialog box.
<!DOCTYPE html>
<html lang="en">
<head>
<title>jQuery Get the Value of an Input Text Box</title>
<script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
<script>
$(document).ready(function(){
// Get value on button click and show alert
$("#myBtn").click(function(){
var str = $("#myInput").val();
alert(str);
});
});
</script>
</head>
<body>
<input type="text" id="myInput">
<button type="button" id="myBtn">Show Value</button>
</body>
</html>
