Question

How to retrieve get or post via javascript only? and not php.

Is it possible?

Answer 1

Obviously you cannot read POST data using javascript because data is POSTed in the body of the HTTP request and only a server side script is capable of reading it. As far as GET data is concerned you could use this function to parse the query string of the current page:

function gup(name) {
    name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regexS = "[\\?&]"+name+"=([^&#]*)";
    var regex = new RegExp( regexS );
    var results = regex.exec(window.location.href);
    if(results == null) {
        return "";
    }
    return results[1];
}

and use like this:

var username = gup('username');
