The :checked selector selects all checked checkboxes or radio buttons. Let us understand this with an example. Selects all checked radio button elements $('input[type="radio"]:checked') Example : When you click the submit button without selecting any radio button, "No radio button checked" message should be displayed. When you click the submit button after a radio button is checked, then a message stating "Male is checked" or "Female is checked" should be displayed. Replace < with LESSTHAN symbol and > with GREATERTHAN symbol. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('#btnSubmit').click(function () { var result = $('input[type="radio"]:checked'); if (result.length > 0) { $('#divResult').html(result.val() + " is checked"); } else { $('#divResult').html("No radio button checked"); } }); }); </script> </head> <body style="font-family:Arial"> Gender : <input type="radio" name="gender" value="Male">Male <input type="radio" name="gender" value="Female">Female <br /><br /> <input id="btnSubmit" type="submit" value="submit" /> <br /><br /> <div id="divResult"> </div> </body> </html> Selects all checked checkbox elements $('input[type="checkbox"]:checked') Example : When you click the submit button without checking any checkbox, "No checkbox checked" message should be displayed. When you click the submit button after checking a checkbox, then a message stating the number of checkboxes checked and their values should be displayed. <html> <head> <title></title> <script src="jquery-1.11.2.js"></script> <script type="text/javascript"> $(document).ready(function () { $('#btnSubmit').click(function () { var result = $('input[type="checkbox"]:checked'); if (result.length > 0) { var resultString = result.length + " checkboxe(s) checked<br/>"; result.each(function () { resultString += $(this).val() + "<br/>"; }); $('#divResult').html(resultString); } else { $('#divResult').html("No checkbox checked"); } }); }); </script> </head> <body style="font-family:Arial"> Skills : <input type="checkbox" name="skills" value="JavaScript" />JavaScript <input type="checkbox" name="skills" value="jQuery" />jQuery <input type="checkbox" name="skills" value="C#" />C# <input type="checkbox" name="skills" value="VB" />VB <br /><br /> <input id="btnSubmit" type="submit" value="submit" /> <br /><br /> <div id="divResult"> </div> </body> </html>
