i've been trying figure out why find method selector not detecting 'city' variable. here's code.
html
<div id="cities"> <div class="denver"></div> <div class="seattle"></div> </div> jquery - data returned getcity.php string "denver, seattle".
$.post("getcity.php", function(data){ var cityarr= data.split(","); $.each(cityarr, function(i, city){ $('#cities').find('.'+city).html(city); }); }); this piece of code not work. if change find('.'+city) find('.denver') or find('.seattle') works.. doing wrong?
i think there whitespace after , in string use trim() or $.trim()
$('#cities').find('.' + city.trim()).html(city); or
$('#cities').find('.' + $.trim(city)).html(city); otherwise need split string comma space.
var cityarr= data.split(/\s*,\s*/);
