javascript - Hide div based on selected dropdown -

-

this code works fine when creating new page. selecting dropdown show or hide decorated markup. problem in edit page default selected id id 3 want div decorated 3 hidden on page load. @ sea javascript , jquery.

<div class="form-group"> <label class="control-label col-md-2" for="articlecategoryid">menu category</label>     <div class="col-md-10">     <select class="chooseoption form-control" id="articlecategoryid" name="articlecategoryid">     <option value="1">pages</option>     <option value="2">about</option>     <option selected="selected" value="3">project</option>     <option value="4">gallery</option>     <option value="5">news</option>     <option value="6">events</option>     <option value="7">faqs</option>     <option value="8">jobs</option>     <option value="9">documents</option>     <option value="10">clients</option>     </select>   <div class="form-group articlecategoryid 3">  <label class="control-label col-md-2" for="articleondate">start date</label>      <div class="col-md-10">     <input class="form-control text-box single-line" data-val="true" data-val-date="the field start date must date." id="articleondate" name="articleondate" type="datetime" value="" />     <span class="field-validation-valid text-danger" data-valmsg-for="articleondate" data-valmsg-replace="true"></span>                 </div>             </div>              <div class="form-group articlecategoryid 1">                 <label class="control-label col-md-2" for="artilceontime">on time</label>                 <div class="col-md-10">                     <input class="form-control text-box single-line" id="artilceontime" name="artilceontime" type="text" value="" />                     <span class="field-validation-valid text-danger" data-valmsg-for="artilceontime" data-valmsg-replace="true"></span>                 </div>             </div>

below jquery snippet

<script type="text/javascript"> jquery(".optionname").hide(); jquery("document").ready(function () {   /// have wait till after document loads run these things jquery("select.chooseoption").change(function () { jquery("." + this.id).hide(); var thisvalue = jquery(this).val(); if (thisvalue != "")  jquery("." + thisvalue).show();         });     }); </script>

this being edit page want "<div class="form-group articlecategoryid 3">....</div> hidden on page load since item id 3 has been selected other should show. appreciated

having components classes given such "articlecategoryid 1" bad idea.

you have sth like

<div class="form-group editable-category" data-category-id="1">    <label class="control-label col-md-2" for="artilceontime">on time</label>    <div class="col-md-10">       <input class="form-control text-box single-line" id="artilceontime" name="artilceontime" type="text" value="" />       <span class="field-validation-valid text-danger" data-valmsg-for="artilceontime" data-valmsg-replace="true"></span>    </div> </div>

and css

.editable-category{   display:none; }  .editable-category.active{   display:block; }

and js follow

$(document).ready(function(){   $('select.chooseoption').on('change',function(){      var thisvalue = $(this).find('option:selected').val();      if(thisvalue){        $('.editable-category.active').removeclass('active');        $('.editable-category[data-category-id="'+thisvalue+'"]').addclass('active');      }   }).trigger('change');  });

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/...
