Question

I want to get an automatic search result, and on one page it DOES work but on the other NOT. Could you tell me what te problem is?

WORKING:

function showUser(str)
{

if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","ordertabel.php?search="+str,true);
xmlhttp.send();
}

NOT WORKING:

function showUser(str,str)
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","klanttabel.php?search="+str"&search2="+str,true);
xmlhttp.send(); 
}

Please note that with the NOT working code there are 2 inputs.

Thanks in advance!

I guess it’s an url encoding problem. Try encoding:

xmlhttp.open("GET", "klanttabel.php?search=" + encodeURIComponent(str) + "&search2=" + encodeURIComponent(str), true);

Also notice that you are missing a + in your string concatenation.
