jquery - Weird output with packery used to randomly position div -


i'm having trouble inserting div (ad banner) randomly within bunch of other divs.

i found working example i'm using question: insert div in random location in list of divs

however, template being inserted within 1 of items/children, rather it's outer container/target.

here's html:

<div class="template" style="display: none;">     <a class="item advertisement">         <div class="item-inner-wrapper">             <img alt="image" src="http://placehold.it/525x765">         </div>     </a> </div>  <div class="listings">      <a class="item card" href="#">         <div class="item-inner-wrapper">             <img alt="" src="http://placehold.it/525x765">         </div>     </a>      <a class="item card" href="#">         <div class="item-inner-wrapper">             <img alt="" src="http://placehold.it/525x765">         </div>     </a>  </div>

the js

    var insertiontemplate = $('.template').find('.item').html(),         insertiontarget = $('.listings'),         insertiontargetchildren = insertiontarget.find('.item'),         insertionfrequency = 1;      var random;     (var = 0; < insertionfrequency; i++) {         random = math.floor(math.random() * insertiontargetchildren.length) + 0;         insertiontargetchildren.eq(random).append(insertiontemplate);     }      $('.listings').packery({         itemselector: '.item'     });

and in output: (notice .item-inner-wrapper placed within last .item, rather it's parent .item being placed within .listings)

<div class="listings">      <a class="item card" href="#">         <div class="item-inner-wrapper">             <img alt="" src="http://placehold.it/525x765"></div>         </div>     </a>      <a class="item card" href="#">         <div class="item-inner-wrapper">             <img alt="" src="http://placehold.it/525x765"></div>         </div>          <div class="item-inner-wrapper">             <img src="http://placehold.it/525x765" alt="image">         </div>     </a>  </div><!-- [end] listings -->

what have got wrong here?

try replace append after

 var insertiontemplate = $('.template').find('.item').html(),             insertiontarget = $('.listings'),             insertiontargetchildren = insertiontarget.find('.item'),             insertionfrequency = 1;      var random;     (var = 0; < insertionfrequency; i++) {         random = math.floor(math.random() * insertiontargetchildren.length) + 0;         insertiontargetchildren.eq(random).after(insertiontemplate);     }      $('.listings').packery({         itemselector: '.item'     });

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
