Why am I getting Unexpected token illegal in javascript? -

-

why getting error "unexpected token illegal" in script? script supposed retrieve cookies , display names , values in table. error occurs on line has opening table tag.

document.getelementbyid("showcookies").onclick = function(){          var columnright = document.getelementbyid('columnright');          var cookies = document.cookie;         var cookiescontent = '<h1>existing cookies</h1>';         console.log(cookies);         cookies = cookies.split(";");          if(cookies.length > 0){              cookiescontent += '<table width="30%" cellspacing="1" cellpadding="10" border="0">             <thead>                 <tr>                     <th>name</th>                     <th>value</th>                 </tr>             </thead>             <tbody>                 ';              for(var = 0; < cookies.length; i++){                  cookieatts = cookies[i].split('=');                 cookiescontent += "<tr><td>" + cookieatts[0] + "</td><td>" + cookieatts[1] + "</td></tr>";              }              cookiescontent += "</tbody></table>";          }          columnright.innerhtml = cookiescontent;          return false;     }

it's because can't have multiline strings in javascript without backslashes:

cookiescontent += '<table width="30%" cellspacing="1" cellpadding="10" border="0"> \             <thead> \                 <tr> \                     <th>name</th> \                     <th>value</th> \                 </tr> \             </thead> \             <tbody> \                 ';

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/...
