What is chater a reference to? normally it would be a reference like (1) chater = document.getElementById("whatever_id_ref"); which chater.value = data; will reference to apply value returned OR jquery would use (2)$("#whatever_id_ref").val(data); (1)JS

function otoload() {var oto_update = <?php echo $id ?>;var url = "../oto_work.php";var chater = document.getElementById("whatever_id_ref");$.post(url,{ oto_update: oto_update }  ,  function(data) {//alert('got response from server, updating page with ' + data);//output.innerHTML = data;});chater.value = data;}); //if (chater.val() == "") {//alert("no info");//} else {alert(chater.val());//} //alert("Page is loaded");otoload_timer = setTimeout("otoload()",10000);}

(2)Jquery

function otoload() {var oto_update = <?php echo $id ?>;var url = "../oto_work.php"; $.post(url,{ oto_update: oto_update }  ,  function(data) {//alert('got response from server, updating page with ' + data);//output.innerHTML = data;});//chater.value = data; $("#whatever_id_ref").val(data);}); //if (chater.val() == "") {//alert("no info");//} else {alert(chater.val());//} //alert("Page is loaded");otoload_timer = setTimeout("otoload()",10000);}

chater is a varible that is empty when the script runs..var chater = "" and in the end i do no want "chater" leaveing the script.am looking to put all the data from oto_work.php in the varible of "chater", and to be used in javascript to run conditions (if, elts and so on..)

Sorry the problem is the alert is outside the function it will never show alert there is no alert to trigger from inside the $.post function ON the first ALERT

function otoload() {  var oto_update = <?php echo $id ?>;var url = "../oto_work.php"; $.post(url,{ oto_update: oto_update }  ,  function(data) {chater = data;alert(chater);}); ///alert(chater); otoload_timer = setTimeout("otoload()",10000);}

Edit: got me adding .val() now
