Ajax: http_request.send problem
Hi, It's getting a usual weekly posting habbit with my coding problems. I usually don't go into Ajax because I'm really not good at it but I have to following problem, I'd like to "Post" some values with Ajax/JS but it does not work.
function update_form(myForm) {
http_request = false;
if (window.XMLHttpRequest) {
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/xml');
}
} else if (window.ActiveXObject) {
try {
http_request = new ActiveXObject("Msxm12.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}
if (!http_request) {
alert('Error create XMLHTTP instance');
return false;
}
theForm = document.getElementById('theform');
theStr = '';
for (i=0; i < theForm.elements.length; i++) {
ele = theForm.elements[i];
theStr += ele.name + ' : ' + ele.value + "n";
}
url = "administration_ajax.php?update=ajax_adm_centerboxes.php";
http_request.onreadystatechange = update_form2;
http_request.open('POST', url, true);
http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http_request.setRequestHeader("Content-length", theStr.length);
http_request.setRequestHeader("Connection", "close");
http_request.send(theStr);
}
function update_form2() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
document.getElementById('status').innerHTML = http_request.responseText;
} else {
alert('Have problems loading new page');
}
}
}
Everything works fine, file is called like it should, but the "POST" data does not arrive. I've tried with "GET" and it arrives good, but i cannot use it, because the URL length might exceed. therefor I really need to find out how to get this to work, and am sure someone knows the answer out here on 9r.
