Check any value numeric or non-numeric via jQuery

Question

Aryan Kumar · Answer

To check if a value is numeric or non-numeric using jQuery, you can use a combination of the
$.isNumeric() function. Here's an example:
andlt;!DOCTYPE html>
andlt;html lang="en">
andlt;head>
  andlt;meta charset="UTF-8">
  andlt;meta name="viewport" content="width=device-width, initial-scale=1.0">
  andlt;title>Check Numeric or Non-Numeric with jQueryandlt;/title>
  andlt;script src="https://code.jquery.com/jquery-3.6.4.min.js">andlt;/script>
andlt;/head>
andlt;body>
andlt;input type="text" id="inputValue" placeholder="Enter a value">
andlt;button id="checkButton">Checkandlt;/button>
andlt;script>
  $(document).ready(function () {
    $('#checkButton').on('click', function () {
      // Get the input value
      var inputValue = $('#inputValue').val();
      // Check if the value is numeric using $.isNumeric()
      if ($.isNumeric(inputValue)) {
        alert(inputValue + ' is numeric.');
      } else {
        alert(inputValue + ' is non-numeric.');
      }
    });
  });
andlt;/script>
andlt;/body>
andlt;/html>
In this example:
An andlt;input> element is used to get a user's input.A andlt;button> element triggers the check.The jQuery code is executed when the button is clicked.The $.isNumeric() function is used to check if the entered value is numeric.An alert is displayed based on whether the value is numeric or non-numeric.
Make sure to include the jQuery library in your HTML file for this to work. Adjust the code as needed for your specific use case.
