JsHttpRequest is an easy-to-use cross-browser AJAX library with AJAX file uploading support and many other features. JsHttpRequest first appeared as cross-browser analogue of XMLHttpRequest, and then became a very useful instrument to create dynamic web pages. It uses JavaScript (ActiveX, DOM, XMLHttpRequest if available) in frontend and PHP in backend.

Here is a short list of library's most interesting features and benefits.

  • Excellent cross-browser compatibility (e.g. works with IE 5.0 with disabled ActiveX).
  • Support and "transparent" work with any character encoding (including any national).
  • AJAX file uploads from a user browser to the server without a page reloading.
  • Full support of PHP debug features and coding traditions.
  • Multi-dimensional data structures exchange (associative arrays).
  • Automatic choice of the best AJAX realization (XMLHttpRequest, <SCRIPT>, <IFRAME>).
  • XMLHttpRequest-compatible interface is available.

The main idea of JsHttpRequest is to be simple and transparent for all programmers and habitual programming techniques:

  • PHP notices and errors (including fatal) are not break the script execution;
  • there is no need of any framework (e.g. classes) to build a server part;
  • PHP arrays are converted to JS objects and back fully transparently;
  • forget about national encodings problems (e.g. works with windows-1251 on PHP part).

Examples:

// JavaScript code:
JsHttpRequest.query(
    'your_ajax_script.php',
    {
        first: 'Dmitry',  
        last: 'Koterov',
        file: document.getElementById("my_upload_file")
    },
    function(result, debugMessages) {
        document.getElementById("result").innerHTML = result.text; 
        if (debugMessages) alert(debugMessages);
    }
);

// PHP code:
require_once "lib/JsHttpRequest.php";
$JsHttpRequest =& new JsHttpRequest("windows-1251");
$_RESULT['text'] = "Hello, {$_REQUEST['first']} {$_REQUEST['last']}!";
echo "Any debug message or even a fatal PHP error";
