Question

The ajax call snipet below returns either ‘found’ or ‘no’ as a string from the server. The first line of the callback alert(d) shows the result returned. However, the line if (d == "found") is never true, even when ‘found’ is returned. Please what am I missing? Thanks for the help.

$.get('includes/reg_fns.php', {
    'op': 'availability',
    'field': $(this).attr('name'),
    'val': val
}, function(d) {
    alert(d);
    if (d == "found") {
        alert("<br /><span style='font-size:83%;color:red; margin-left:117px'>&nbsp;[ <b>*</b> " + val + " is already taken.</span><br />");
    } else {
        alert('false here');
    }
});​

Answer 1

may be you are returning with extra space on it.

try using trim() on it.

if( d.trim()=='found')
