multiple div refresh

[robert_gsfame]

Below is the script

 

function refreshflag()

{

var totalx=document.getElementById("totaluser").value;

var spx=totalx.split(";");

if (window.XMLHttpRequest)

  {// code for IE7+, Firefox, Chrome, Opera, Safari

  xmlhttp=new XMLHttpRequest();

  }

else

  {// code for IE6, IE5

  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");

  }

for(i=0;i<spx.length;i++)

{

var parameters="em="+spx;

xmlhttp.open("POST","refresh_flag.php",true);

xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded")

xmlhttp.onreadystatechange=function()

  {

  if(xmlhttp.readyState==4 && xmlhttp.status==200)

    {

    document.getElementById("ref"+spx).innerHTML=xmlhttp.responseText;

    }

  }

xmlhttp.send(parameters)

}

setTimeout("refreshflag()", 1000);

 

The problem is that in refresh_flag.php, when i cannot get the result which is $_POST['em'] displayed as document.getElementById("ref"+spx).innerHTML) although in refresh_flag.php, i put this echo $_POST['em'];

 

as if $_POST didn't pass the value

 

thx for any help

[brianlange]

your parameters variable should be =

"ref" + spx[i]; 

you are setting it to the entire spx array.

 

The second issue is that the for loop will run too fast to receive each response.

pass in false as the third parameter to make the request synchronous.

 

Here's a working example. View source to see the js code. http://www.realtown.com/test20.php
