The harmonious combination of Opera and XMLHttpRequest creates a

Coming from Russia, please excuse any mistakes in my English.

I am trying to dynamically load the main page of my website using JavaScript, and I have written this script:

<script type="text/javascript">
    function httpGet(theUrl) {
    var xmlHttp = null;
    xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", theUrl, false );
    xmlHttp.send(null);
    return xmlHttp.responseText;
    }
 alert(httpGet('http://site.ru'));
</script>

The script is located at site.ru/page123.

It works correctly in Firefox and successfully alerts the main page, but when running it in Opera, nothing seems to happen. Please help me fix this code as I cannot identify any errors. Thank you in advance.

Answer №1

When it comes to XHR, it is typically asynchronous (switching to synchronous mode is not recommended as it can lead to browser freezing). It is advisable to use a callback instead.

Dealing with XHR manually can be tedious, so my recommendation is to utilize jQuery. By using jQuery, your code will be simplified and more streamlined:

$.get('http://site.ru', function(resp) {
    alert(resp);
});
