html - javascript custom event fire from a function with returning false -


i have following form code. , have prevent form submission , after firing custom event. have written javascript on submit function triggering event , return false, please if doing wrong.

form html:

   <form class="form-inline" action="" name="filterform">       <div class="row">         <?php foreach($formatted_post_type $filters){?>         <div class="checkbox">           <label class="checkbox-inline" style="line-height:40px;">             <input type="checkbox" name="filters[posttype][]" value="<?php echo $filters['slug']?>" onclick="refresh_posttypes();" />             <?php echo $filters['name']?></label>         </div>         <?php }?>       </div>       <div class="row">         <div class="col-md-12">           <input type="submit" class="btn btn-primary btn-sm" value="apply">         </div>       </div>     </form>

javascript code:

jquery(document).ready(function(){   jquery('form[name="filterform"]').on('submit', function(e){       jquery(document).triggerhandler('favorites-update-all-lists', function(e){            e.preventdefault();     });     return false;     });   });

try moving e.preventdefault(); right after submit handler:

jquery(document).ready(function(){   jquery('form[name="filterform"]').on('submit', function(e){       e.preventdefault();        jquery(document).triggerhandler('favorites-update-all-lists', function(e){        });     return false;     });   });

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
