hello everybody when searching in net i came to know that, to post data to server using ajax i have to use the following method..... req.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); req.send("id=" + escape(field.value)); when there is so much elements in the form , for example more than 50 then encoding all this values to url and sending it using the method req.send(); becomes very difficult and some browsers does not allow so much long url encoding. i tried req.send(document.form); but it also doesn't work so is there any way to post data to se   More>>
