Problem with AJAX API

I want the program to say "We couldn't find it" when the searched item is not found, but, it doesn't work. What am i doing wrong? Please help.

$(document).ready(function() {

$('form').submit(function (evt) { // highlight the button // not AJAX, just cool looking // the AJAX part var $searchField = $('#search'); var $submitButton = $('#submit'); $searchField.prop('disabled', true); $submitButton.attr('disabled', true).val('searching......'); evt.preventDefault(); var flickerAPI = "http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?"; var input = $('#search').val(); var flickrOptions = { tags: input, format: "json" }; $.getJSON(flickerAPI, flickrOptions, displayPhotos);

function displayPhotos(data) {
  var photoHTML = '<ul>';
  $.each(data.items, function(i, photo) {
    photoHTML += '<li class="grid-25 tablet-grid-50">';
    photoHTML += '<a href="' + photo.link + '" class="image">';
    photoHTML += '<img src="' + photo.media.m + '"></a></li>';
  }); // end each
  photoHTML += '</ul>';
  if(photoHTML == null) {
     $('#photos').html("We couldn't find it");
} else {
    $('#photos').html(photoHTML); 
}
  $searchField.prop('disabled', false);
  $submitButton.attr('disabled', false).val('Search');

}

$.getJSON(flickerAPI, flickrOptions, displayPhotos);

}); // end click }); // end ready

Is it never dropping into the line "We couldn't find it" ?

If so, quick glance, the problem seems to lie with:

  var photoHTML = '<ul>';
        ...
  photoHTML += '</ul>';
  if(photoHTML == null)

The variable photoHTML is never null because before/after your ajax call, you already assign it to something (in these cases, strings.

I have tried ways too. Like: if(data.items === []). But it just won't work. i know for sure that the problem lies in the if statement, but, i cannot find the right solution.
