javascript variable to php

want html variable to be from js to php

[ikbenhet1]

I have a javascript function that reads a website's content in a string.

How do i pass the content from js to php? do i need encode the string in any way?
I've tried it with meta refresh, but it didn't work as expected. Have any tips?

Use JavaScript to put the information in a form field, then submit the form and use php to read it. The form field can be hidden, and if you don't want your page to disappear when the form submits you could put the form in a hidden iFrame so that only the iFrame gets submitted.

Thanks, that's what i was trying, but my code doesn't work, can anybody spot the error? The input field doesn't get populated.

content="";
var xmlhttp = new ActiveXObject("MSXML2.XMLHTTP");
xmlhttp.open( 'GET', 'http://www.example.com' , true);
xmlhttp.onreadystatechange = function(){
if (xmlhttp.readyState == 4)
content=xmlhttp.responseText;

}
xmlhttp.send(null);
document.write('<form action="http://www.example.com/tst.php" method="post"><input type="text" value="'+content+'" name="content1"><input type="submit" value="doen"></form>');

<edit> figured it out </edit>
