javascript - Execute your own JSONP function -

-

i using jsonp , , url(action) returning me function called processtemplates. there way can execute own function instead of processtemplates.

something _processjsoncallback

    function _processoveridecallback(actionname) {          $.ajax({                 type: 'get',                 url: actionname,                 async: false,                 contenttype: "application/javascript",                 jsonpcallback: '_processjsoncallback',                 datatype: "jsonp",                 error: function(jqxhr, exception) {                 if (jqxhr.status === 0) {                     alert('not connect.\n verify network.');                 } else if (jqxhr.status == 404) {                     alert('requested page not found. [404]');                 } else if (jqxhr.status == 500) {                     alert('internal server error [500].');                 } else if (exception === 'parsererror') {                    alert('requested json parse failed.');                 } else if (exception === 'timeout') {                     alert('time out error.');                 } else if (exception === 'abort') {                     alert('ajax request aborted.');                 } else {                     alert('uncaught error.\n' + jqxhr.responsetext);                 }             }         }); };

but when trying throwing exception "requested json parse failed."

please me on this.

from jquery docs:

cross-domain requests , datatype: "jsonp" requests not support synchronous operation

you getting error because have async: false.

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/...
