Question

I’m using an ajax post like so…

$(document).on("click",".Resend",function() {

    $.ajax({
        type: "POST",
        url: "file.php",
        timeout: 3000,
        data: dataString,
        cache: false,
        success: function(myhtml){
            // If success
            if (myhtml == "success") {
                    alert(myhtml);
            } else {
                    alert("No");
            }
        }
    });
});

The PHP/HTML that is called back for example is a simple as this…

<?php
    echo "success";
?>

For some odd reason I am getting the false return alert = No. Can someone explain to me why this might happen?

Answer 1

Assuming that the page you’re posting to exists, it is possible that the contents of the response includes some white space; therefore, the string comparison would fail.

You can try this:

if ($.trim(myhtml) == 'success') {
  alert(myhtml)
}
