Answer 3

You can decide alternatively, i.e. read the result of executing this function from the desired page. Will this solution work for you? If yes, then I will write it to you.

You write this script on the page where this function is executed:

Answer 5

function getXmlHttp(){
var xmlhttp;
try {
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (E) {
xmlhttp = false;
}
}
if (!xmlhttp && typeof XMLHttpRequest!='undefined') {
xmlhttp = new XMLHttpRequest();
}
return xmlhttp;
}
function getrec(set_any_result) {
var xmlhttp = getXmlHttp();
xmlhttp.open("GET", \' xxx.site.ru/index.htm?set_any_result='+set_any_result+'\');
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4) {
window.parent.frames[1].document.close();
window.parent.frames[1].document.open();
window.parent.frames[1].document.write(xmlhttp.responseText);
}
}
xmlhttp.send();
}

Answer 6

If the main page and the page from the iframe had the same domain, then it would be possible to call
window.top.needed();
But since in iframe we display a page from a subdomain, then this will not work.
But it turns out that this can be bypassed by changing the domain on the main page and on the iframe page and set the domain for both from the root site. Then js functions can be called like this
window.top.needed();

You can, however, use a less rational, but more understandable option. You can share the result with another page through invisible text fields. Well, for example, like this:
the main window is
the window with the text
the text of the named window
