Passing a URL string to a Javascript function

I need to pass a URL to a JavaScript function something like the following. 

<script type="text/javascript" language="javascript">

var xmlhttp='';   
function ajax()
{
    if(window.XMLHttpRequest)
    {
        xmlhttp=new XMLHttpRequest();
    }
    else
    {
         xmlhttp = new ActivexObject("Microsoft.XMLHTTP");
    }
}     

function someFunction(orders_per_page, url)
{
     ajax();
     var val=document.getElementById("txt_order_amount").value; 
     xmlhttp.onreadystatechange=function()
     {
          if(xmlhttp.readyState==4 && xmlhttp.status==200)
          {                
               document.getElementById("list").innerHTML=xmlhttp.responseText;
          }
     }

     xmlhttp.open("GET",url, true);
     xmlhttp.send();        
}
</script>

<select 
    id="cmb_page" name="cmb_page" 
    onchange="someFunction(this.value, "reports/OrderAmount.php?val="+val+"&orders_per_page="+orders_per_page+"&pageNo="+getSelectedPage();">

    <option value="1">Some Value</option>
</select>

I need to pass a URL string as mentioned on the onchange even of the <select><option></option></select> element. Is it possible?

You can also break your code a little bit to prevent as much tag soup.

I assume your val var is defined and in the global scope:

onchange="someFunction(this.value)"

function someFunction(orders_per_page) {
    var url = "reports/OrderAmount.php?val="+val+"&orders_per_page="+orders_per_page+"&pageNo="+getSelectedPage();
    ajax(); // ... rest of your function

Make sure getSelectedPage() is returning a string, or a number which can be parsed as string.

try this

onchange="someFunction(this.value, 'reports/OrderAmount.php?val='+val+'&orders_per_page='+orders_per_page+'&pageNo='+getSelectedPage());"

Note: I have replaced double quotes with single quotes
