Question

I have a form as

<form action="" method="post">

<input name="Descripcion" type="hidden" value="" id="Descripcion" runat="server" />

<input id="Submit1" type="submit" value="Comprar" />

Instead of clicking on submit button i want that the form should be posted without clicking submit button with hidden fields

Answer 1

You can submit an html form from javascript by calling the form’s .submit() method. e.g.:

document.getElementById('myform').submit();

Of course, you still need an action in your example so the form has somewhere to submit itself to. Also, you tagged your question asp.net. If this is a webforms page you should use the default form rather then adding your own form to the html markup. You submit the asp.net form by calling the __doPostBack() method.
