i have this script and its working fully...

window.onload = otoload;function otoload() {var oto_update = <?php echo $id ?>;var url = "../oto_work.php";$.post(url,{ oto_update: oto_update }  ,  function(data) {chater = data;if (chater == "") {$("#whatisit").html('<a href="#" title="chat" onclick="return false" onmousedown="javascript:togglechat(\'chat\');"><img src="../image/chat.png" alt="chat" width="44" height="40" /></a>').show();} else {    $("#whatisit").html('<a href="#" title="chat" onclick="return false" onmousedown="javascript:togglechat(\'chat\');"><img src="../image/chat2.gif" alt="chat" width="44" height="40" /></a>').show();//$("#mem+chater").class.back3// code needed}});otoload_timer = setTimeout("otoload()",10000);}

now i need to add one line of code to finish it. The logic is i have many divs and the id of the divs is mem and a number (mem25 mem268 mem739 mem6 and so on...)the info in the varible "chater" hold numbers separaded by , (25,268,739,6 and so on...)for each number in the varible chater i am trying to make the div class change to back3 any help?

[Err]

If chater is an array you can loop through the numbers and assign back3 every time.

var cnt = chater.length;for (var i = 0, i < cnt; i++) {  $("#mem"+chater[i]).class.back3;}

when i put your code in the place where i wrote// code neededit does not work and i can not see my image

[dsonesuk]

var num_list=chater.split(",");for (var i = 0; i < num_list.length; i++) {  $("#mem"+num_list[i]).removeClass("whatever_class").addClass("back3");}

[westman]

with...

var num_list=chater.split(",");for (var i = 0; i < num_list.length; i++) {  $("#mem"+num_list[i]).removeClass("whatever_class").addClass("back3");}

i can see my image but it is not working...i left .removeClass("whatever_class") as it was coz the class will be "back1" or "back2" (set by php diynamicly)

[westman]

i used...$("#mem"+num_list).removeClass("back2").addClass("back3");and$("#mem"+num_list).removeClass("back1").addClass("back3");and it still did not change

[dsonesuk]

Well keep going I'm pretty sure your hit the correct solution pretty soon, it's like we can't do anything this end, as we have no idea what the html code with id, and classes looks like, or any js errors you are getting, so we can't help can we!

[westman]

am closer....i usedalert(num_list);to see the code on the screen and saw it..in alert(num_list); i saw the number folowed by , (25,)if we can remove the , (25) it would work how do i remove the , ?

[dsonesuk]

var num_list=chater.slice(0,-1)num_list=num_list.split(",");for (var i = 0; i < num_list.length; i++) {  $("#mem"+num_list[i]).removeClass("whatever_class").addClass("back3");}

[westman]

i still have the , if the div is called <div id= "mem25">the code at the mo is looking for <div id= "mem25,">

[dsonesuk]

Not its NOT! you made a mistake somewhere, it will never show the comma, the number after the comma will be stored.

[westman]

omg its working ;)i dont know what happend but thank you so much thank you

[westman]

my finel edit i now have...

window.onload = otoload;function otoload() {var oto_update = <?php echo $trueid ?>;var url = "../livechat/oto_work.php";$.post(url,{ oto_update: oto_update }  ,  function(data) {chater = data;if (chater == "") {$("#whatisit").html('<a href="#" title="T-chat" onclick="return false" onmousedown="javascript:toggletchat(\'tchat\');"><img src="../image/chat.png" alt="T-chat" width="44" height="40" style="border:0;" /></a>').show();//code needed} else {    $("#whatisit").html('<a href="#" title="T-chat" onclick="return false" onmousedown="javascript:toggletchat(\'tchat\');"><img src="../image/chat2.gif" alt="T-chat" width="44" height="40" style="border:0;" /></a>').show();var num_list=chater.slice(0,-1)num_list=num_list.split(",");for (var i = 0; i < num_list.length; i++) {  $("#mem"+num_list[i]).removeClass("back2").addClass("back3");}}});otoload_timer = setTimeout("otoload()",10000);}

and it is working fullyis there a way that i can set all divs to Class back2 without knowing the div id's?

[dsonesuk]

var num_list=chater.slice(0,-1)num_list=num_list.split(",");$("div").addClass("back2");for (var i = 0; i < num_list.length; i++) { $("#mem"+num_list).removeClass("back2").addClass("back3");}

[westman]

but in post 13 where i have...//code neededchater == "" so i do not know the div id's.is it posible to set all div's starting with "mem" to Class back2?

[dsonesuk]

$('[id^=mem]').addClass("back2");

[westman]

its not working, the div's whitch we do not have the id's for (but starting with mem in the id) are not changeing back to class back2

[dsonesuk]

Yes they do!

[westman]

got it... $('[id^=mem]').removeClass("back3").addClass("back2"); working well thank you very much for your time again thank you
