    <script type="text/javascript"> function startAjax(url){ var request; if(window.XMLHttpRequest){ request = new XMLHttpRequest(); } else if(window.ActiveXObject){ request = new ActiveXObject("Microsoft.XMLHTTP"); } else { return; } request.onreadystatechange = function(){ switch (request.readyState) { case 4:{ if(request.status==200){ var foo = request.responseText; alert ( foo ); } else alert("Ошибка: сервер вернул статус: "+ request.status); break } } } request.open ('GET', url, true); request.send (''); } window.onload = startAjax('url'); </script>

    In the row window.onload = startAjax('url'); , url - replace with address

    • Not quite understand the question. I need a variable to assign the page content to a specific address. - Saturn
    • @Saturn in the same domain? - zb '
    • Not. I apparently incorrectly formulated the question. The value of the variable must be obtained from the content of the page at a specific address - Saturn
