String Compare Failure in javascript

Question

 <div id="error" class="modal fade">
        <div class="modal-dialog">
            <div class="modal-content">
                <div class="modal-header">
                    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                    <h4 class="modal-title" id="modal_head">Activation</h4>
                </div>
                <div class="modal-body">


                    **<p id="error_record"> <?php echo $msg; ?> </p>**           \\line 1


                    <p class="text-warning"><small id="direction"></small></p>

                </div>
                <div class="modal-footer" align="center">
                    <button onclick="redirect()" type="button" class="btn btn-primary" >Okay</button>
                </div>
            </div>
        </div>
    </div>

I need to compare the string in the div with id "error_record" as follows :

<script>
        window.onload=function()
        {
            $("#error").modal('show');
        }
        function redirect(){
            var val=document.getElementById("error_record").innerHTML;      \\line2
            alert(val);                                                      \\line 3
            if(val=="Invalid Link"||val=="Invalid Link."||val=="Empty Link")
            {
                window.location="index.php";
            }
            if(val=="Activation Successful"||val=="Your Account is already activated.")
            {
                window.location="dashboard.php";
            }
        }
    </script>

But it always returns false in the comparison, in comment line 2.

The alert in comment line 3 gives the same string, But the comparison returns false.

Does it have something to do with the echo in line 1?

i have $msg="Empty Link";

what do you mean by "But it always returns false in the comparison, in comment line 1." — Abdallah Arffak

please read $msg="Empty Link"; The string ought to be same but the comparison doesnt work. — user3738510

You have whitespaces where i have written underscores <p id="error_record">_<?php echo $msg; ?>_</p>, that is why your strings are not equat. Either remove the whitespaces, or use .trim() fuction on your innerHTML to remove the whitespace.

You mean all the white spaces??

no, only inside <p> tag ( the ones that i replaced with the underscores ) the whitespaces inside $msg are fine.

Instead of using (double equals) ==

use indexOf() != -1 as shown below code and let me know whether it works or not:

if(val.indexOf("Activation Successful")!=-1||val.indexOf("Your Account is already activated.")!=-1) {
    window.location="dashboard.php";
}
