Question

I have a jquery post method that sends name , password and email to register.php

function postData()
{
    thisBtn = $(this); 
    parent = $(this).parent(); 
    name = parent.data('name'); 
    password = parent.data('password'); 
    email =parent.data('email');
    $.post('register.php', {name: (name), password: (password), email: (email)},     function(data) ;
    parent.next('#message').html(data);
}

The button that performs the function onclick:

<button onclick = 'postData()' class='regular' name='save'>

However nothing seems to be happening when the button is cicked

Answer 1

Since you call postData with no associated object, inside the function this is the same as window so none of the elements you access are the ones you expect.

Don’t use intrinsic event attributes, bind your handlers using JavaScript. Since you are already using jQuery you should use the methods it provides for that.
