    AJAX:Problem in responseText if condition equal to responseText but fall to else

    Hi,

    Good day!

    I encountered problem on my ajax code. I think it my responsetext has a whitespace so that it falls on my else statement.

    here is my ajax code:

    Code:
    //----barcode---//
    function get_data(){
        if (window.event.keyCode==13 || window.event.keyCode==10) {
        var barcode_wms = document.getElementById("barcode").value;
       // var divid = 'display_data';
        var url = "getbarcode_data.php";
        var str = "mc=" + barcode_wms;
    
        var xmlHttp = AJAX();
    
       // alert(xmlHttp);
        xmlHttp.onreadystatechange=function(){
        //alert("test");
       /*
        if(xmlHttp.readyState > 0 && xmlHttp.readyState < 4){
          //  document.getElementById(divid).innerHTML=loadingmessage;
            }
        */    
        if (xmlHttp.readyState == 4 && xmlHttp.status == 200) {
            //alert('test');
                var jsonart = xmlHttp.responseText;
                //jsonart = jsonart.Itrim()
                alert(jsonart);
                if(jsonart==="Invalid")
                {
                 alert("Invalid Barcode");
                    //notify("Invalid Barcode");
                 //refresh(1500);
                }
                else
                {
                    alert("Correct Barcode");
                /*    
                var strsplit = jsonart.split("^");
                document.getElementById("po_number").value = strsplit[0];
                document.getElementById("unique_id").value = strsplit[1];
                document.getElementById("kind").value = strsplit[2];
                document.getElementById("material_code").value = strsplit[3];
                document.getElementById("description").value = strsplit[4] ;
                document.getElementById("uom").value = strsplit[5] ;
                document.getElementById("supplier").value = strsplit[6] ;           
                document.getElementById("qty").value = strsplit[7] ;
                }
                */
                }
            //}
        }
        }
        xmlHttp.open("POST", url, true);
        xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xmlHttp.setRequestHeader("Content-length", str.length);
        xmlHttp.setRequestHeader("Connection", "close");
        xmlHttp.send(str);
       // }
    }
    }
    get_barcode_data.php

    PHP Code:
    <?php
    include("includes/connection.php");
    //if($_POST["mc"])
       // {
        
    $barcode $_POST['mc'];
        
    $po_number substr($barcode05);  
        
    $item_code substr($barcode56);  
        
    $supplier substr($barcode113);  
        
    $uom substr($barcode142); 
        
    $unique_id substr($barcode166); 
        
    $qty substr($barcode22);   
        
    $query "SELECT mat_id, supplier_id, uom_id ";
        
    $query .= "FROM check_info ";
        
    $query .= "WHERE mat_id = '$item_code' AND supplier_id = '$supplier' AND uom_id = '$uom'";
        
    $result mysql_query($query);
        
    $cnt mysql_num_rows($result);
        if(
    $cnt==0)
        {
            echo(
    "Invalid");
        }
        else
        {
            echo(
    "Correct");
        }
        exit;
    and the index.php
    PHP Code:
    <?php
        
    include('includes/connection.php');
    ?>

    </form>
    </body>
    </html>
    I can't figured out what is the cause why it did not fall into if condition even the value of responsetext is Invalid.


    I hope somebody can help me.

    Thank you.

    Try
    Code:
    if( /\bInvalid\b/i.test( jsonart ) )
     ...
    Tab-indentation is a crime against humanity.
