How can I clear the default value of an input form onfocus with jquery and clear it again when tha submit button is pressed?
<html> <form method="" action=""> <input type="text" name="email" value="Email address" class="input" /> <input type="submit" value="Sign Up" class="button" /> </form> </html> <script> $(document).ready(function() { //hide input text $(".input").click(function(){ if ($('.input').attr('value') == ''){ $('.input').attr('value') = 'Email address'; alert('1');} if ($('.input').attr('value') == 'Email address'){ $('.input').attr('value') = ''} }); }); </script>

To clear an input field after submitting:Add a click event listener to a button. When the button is clicked, set the input field's value to an empty string. Setting the field's value to an empty string resets the input.
You may use this..
<body> <form method="" action=""> <input type="text" name="email" class="input" /> <input type="submit" value="Sign Up" class="button" /> </form> </body> <script> $(document).ready(function() { $(".input").val("Email Address"); $(".input").on("focus", function() { $(".input").val(""); }); $(".button").on("click", function(event) { $(".input").val(""); }); }); </script> Talking of your own code, the problem is that the attr api of jquery is set by
$('.input').attr('value','Email Adress'); and not as you have done:
$('.input').attr('value') = 'Email address'; 
$(document).ready(function() { //... //clear on focus $('.input').focus(function() { $('.input').val(""); }); //clear when submitted $('.button').click(function() { $('.input').val(""); }); });
