Submit form without page reloading-第2页回答

I have a classifieds website, and on the page where ads are showed, I am creating a "Send a tip to a friend" form...

So anybody who wants can send a tip of the ad to some friends email-adress.

I am guessing the form must be submitted to a php page right?

<form name='tip' method='post' action='tip.php'>
Tip somebody: <input name="tip_email" type="text" size="30" onfocus="tip_div(1);" onblur="tip_div(2);"/>
 <input type="submit" value="Skicka Tips"/>
 <input type="hidden" name="ad_id" />
 </form>

When submitting the form, the page gets reloaded... I don't want that...

Is there any way to make it not reload and still send the mail? Preferrably without ajax or jquery...

Thanks

if you're submitting to the same page where the form is you could write the form tags with out an action and it will submit, like this

<form method='post'> <!-- you can see there is no action here-->

I've found what I think is an easier way. If you put an Iframe in the page, you can redirect the exit of the action there and make it show up. You can do nothing, of course. In that case, you can set the iframe display to none.

<iframe name="votar" style="display:none;"></iframe>
<form action="tip.php" method="post" target="votar">
    <input type="submit" value="Skicka Tips">
    <input type="hidden" name="ad_id" value="2">            
</form>

Here is some jQuery for posting to a php page and getting html back:

$('form').submit(function() {
    $.post('tip.php', function(html) {
       // do what you need in your success callback
    }
    return false;
});

this is exactly how it CAN work without jQuery and AJAX and it's working very well using a simple iFrame. I LOVE IT, works in Opera10, FF3 and IE6. Thanks to some of the above posters pointing me the right direction, that's the only reason I am posting here:

<select name="aAddToPage[65654]" 
onchange="
    if (bCanAddMore) {
        addToPage(65654,this);
    }
    else {
        alert('Could not add another, wait until previous is added.'); 
        this.options[0].selected = true;
    };
" />
<option value="">Add to page..</option>
[more options with values here]</select>

<script type="text/javascript">
function addToPage(iProduct, oSelect){
    iPage = oSelect.options[oSelect.selectedIndex].value;
    if (iPage != "") {
        bCanAddMore = false;
        window.hiddenFrame.document.formFrame.iProduct.value = iProduct;
        window.hiddenFrame.document.formFrame.iAddToPage.value = iPage;
        window.hiddenFrame.document.formFrame.submit();
    }
}
var bCanAddMore = true;</script> 

<iframe name="hiddenFrame" style="display:none;" src="frame.php?p=addProductToPage" onload="bCanAddMore = true;"></iframe>

the php code generating the page that is being called above:

if( $_GET['p'] == 'addProductToPage' ){  // hidden form processing
  if(!empty($_POST['iAddToPage'])) {
    //.. do something with it.. 
  }
  print('
    <html>
        <body>
            <form name="formFrame" id="formFrameId" style="display:none;" method="POST" action="frame.php?p=addProductToPage" >
                <input type="hidden" name="iProduct" value="" />
                <input type="hidden" name="iAddToPage" value="" />
            </form>
        </body>
    </html>
  ');
}

You can try setting the target attribute of your form to a hidden iframe, so the page containing the form won't get reloaded.

I tried it with file uploads (which we know can't be done via AJAX), and it worked beautifully.

You'll need to submit an ajax request to send the email without reloading the page. Take a look at http://api.jquery.com/jQuery.ajax/

Your code should be something along the lines of:

$('#submit').click(function() {
    $.ajax({
        url: 'send_email.php',
        type: 'POST',
        data: {
            email: 'email@example.com',
            message: 'hello world!'
        },
        success: function(msg) {
            alert('Email Sent');
        }               
    });
});

The form will submit in the background to the send_email.php page which will need to handle the request and send the email.
