success callback

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?

A JSON response format would avoid this kind of annoying issues with plain text.

I answered a similar question here: Unable to compare two Strings in javascript

I think you might have the same problem.

Try do something like this in your success callback and see what the response text looks like:

alert('"' + myhtml + '"');

I'm suspecting there's leading or trailing space in your response. That might happen if there's space before your php starting or after the closing tag.

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)
}
