问题 I have the following form. I'd like it to be submitted automatically via jQuery when the user makes a selection, without needing to press the submit button. How do I do this? <form action="" method="post"> <select name="id" id="cars"> <option value="">Choose</option> <option value="1">Toyota</option> <option value="2">Nissan</option> <option value="3">Dodge</option> </select> <input type="submit" name="submit" value="Submit"> </form> adeneo, I tried your suggestion but it's still not working.
