php - Populated options from database doesn't run script on change -

-

i load options select database (which loads options) , trying run script when selected option changes (which doesn't run) script below

<script> $(function() {      function subrace()     {         var race = $("#race").val();          console.log(race + "!");     }      $("#race")       .selectmenu()       .selectmenu(       {           change:  subrace()       })       .selectmenu("menuwidget")       .addclass("overflow");  });  </script>   <select name="race" id="race"> <?php  $dbhost = "localhost"; $dbuser = "dand_user"; $dbpass = "****************"; $dbname = "dand_user";  $mysqli = new mysqli($dbhost, $dbuser, $dbpass, $dbname);  $query = "select * races order name asc";  $result = mysqli_query($mysqli, $query); $x = 0; while($row = $result->fetch_array(mysqli_both)) {     echo"    <option value=\"" . $row['name'] . "\">" . $row['name'] . "</option>\n";     $x++; }  if($x === 0) {     echo"<option disabled selected>no races available</option>"; } ?> </select>

the script is in head element , once script run i'll adjusting console peice see if runs

through working on code further discovered answer can't lay out function want run in situation need enclose in function

<script> $(function() {      function subrace()     {         var race = $("#race").val();          console.log(race + "!");     }      $("#race")       .selectmenu()       .selectmenu(       {           change:  function( event, ui )           {               subrace();           }       })       .selectmenu("menuwidget")       .addclass("overflow");  });  </script>   <select name="race" id="race"> <?php  $dbhost = "localhost"; $dbuser = "dand_user"; $dbpass = "****************"; $dbname = "dand_user";  $mysqli = new mysqli($dbhost, $dbuser, $dbpass, $dbname);  $query = "select * races order name asc";  $result = mysqli_query($mysqli, $query); $x = 0; while($row = $result->fetch_array(mysqli_both)) {     echo"    <option value=\"" . $row['name'] . "\">" . $row['name'] . "</option>\n";     $x++; }  if($x === 0) {     echo"<option disabled selected>no races available</option>"; } ?> </select>

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
