use open event of dialog which is called whn dialog opens... so replace the value there..

$( "#dialog-modal" ).dialog({
 open: function( event, ui ) {
     var boxInput=$("#befor-box").find('input[name="email"]').val(); //get the value..
     $("#dialog-modal").find('input[name="email"]').val(boxInput); //set the valu

 }
});

Emanuel, start by reading some useful info:

http://www.w3schools./jquery/jquery_selectors.asp "The #id Selector" chapter especially.

After that, you can add 'id' attributes to your DOM structure and retrieve input value as simple as

$('#my-input-id').val()

Add an id on both inputs:

<input name="email" type="text" value="Enter your Email here" class="text" id="email_orig"/>

<input name="email" type="text" value="" class="text" id="email_dst"/>

Then override the open event:

    function showDialog()
    {
    $( "#dialog-modal" ).dialog({
         open: function(){
         $("#email_dst").val($("#email_orig").val())
    }
    });

You can use:

$("input[name=email]");

For Bootstrap Modal:

$('.modal-body input[name=email]').val(email);
