generate and compress html and send in response to ajax request then decompress with jquery/js
Ok. So I have a ajax request that I send to the server. This response contain the html that I am going to append to the site. My goal is to never reload the page, instead remove and add html with ajax requests in the background.
First I am not sure how I am going to generate the HTML with php. I want to create a table with previous successful logins. Something like this:
$html = <<<HTML
<div class="box">
<h2>
<a id="toggle-logins">Previous logins</a>
</h2>
<div class="block" id="logins">
<table>
<tr>
<th>Country</th>
<th>City</th>
<th>IP address</th>
<th class="currency">Time</th>
</tr>
<tr>
<td>Norway</td>
<td>Oslo</td>
<td>192.168.1.155</td>
<td class="currency">2011-04-15 04:00</td>
</tr>
</table>
</div>
</div>
HTML;
But how do I add a for loop for example into the mix so I can use arrays from the db to generate tables?
Next I send the json back.
$data = array( "message" => T_gettext("previous logins received"), "html" => $html );
return json_encode( $data );
Then I append it to the site with
var data = jQuery.parseJSON(data);
$("x")
.append(data.html)
This works fine, but I would like to know how to password encrypt and compress the $data or $html variable with php and 开发者_JAVA百科then use jquery to decompress and decrypt it if this is possible. The password encryption might not be necessary in this example, but I would like to password encrypt chat and other features in the future.
Something like:
$html = super_encryption($html, $password);
then in jquery
data.html = super_decryption(data.html, password);
just gzip the content. Browsers support this so no jQuery needed. Enable this by
<?php
ob_start("ob_gzhandler");
?>
As for password-protection. Just use SSL (https). There's no real safe javascript based way of encrypting your data.
