jQuery change Events
change
The change event is triggered when the form field status changes: for instance, when someone clicks a radio button, or makes a selection from a dropdown menu or enter some text in an imput box. You can use this event to immediately check the selection made in a menu, or which radio button was selected.
Let us learn with a simple example.
<!DOCTYPE html> <html> <head> <script type="text/javascript" src="jquery-1.8.0.min.js"></script> <script> $(document).ready(function(){ $("input").change(function(){ $("span").text("Form Field change event fired"); }); }); </script> </head> <body> <input type="text"> <br /> <input type="radio"> <br /><br /> <span>Write some text in the input field, and then press enter or click outside the field</span> <br /> <p>Or click the radio button</p> </body> </html> |
The change event works only with form.
