javascript - Why can't I trigger default click after acquiring more parameters for an href via AJAX? -

-

i trying search vendors within mileage radius, in order need coordinates address i'm searching. it's not feasible grab these coordinates front because map search isn't used often.

so, want grab coordinates google maps when link clicked (if haven't gotten them already), then continue default browser behavior. code have accomplish this:

html

<a href="/vendors/search" target="_blank" class="vendormapsearch"     data-miles-radius="50" data-address="@model.address.singleline()"     data-customer-name="@model.customername" data-customer-id="@model.customerid"    data-service-on="@model.serviceon">vendor map search</a>

javascript

$(document).on('click', 'a.vendormapsearch', function (e) {     console.log('handle click');     var $target = $(e.target),         data = $target.data();      if (!data.latitude || !data.longitude) {         console.log('hitting google maps');         var url = 'https://maps.googleapis.com/maps/api/geocode/json?language=en&sensor=false&address=' + data.address;          $.getjson(url, function (resp) {             console.log('response received');             if (!resp.results.length) {                 $('<div>could not find coordinates address entered.</div>');                 return;             }              $target.data('latitude', resp.results[0].geometry.location.lat);             $target.data('longitude', resp.results[0].geometry.location.lng);              $target.attr('href', $target.attr('href') + '?' + $.param($target.data()));              $target.trigger('coordinatesacquired');         });          return false;     }      console.log('returning true');     return true; });  $(document).on('coordinatesacquired', function() {     console.log('coordinates acquired');     $('a.vendormapsearch').trigger('click'); });

it gives output:

handle click  hitting google maps  xhr finished loading: (blah blah) coordinates acquired handle click  returning true

it looks correct me, behavior not trigger default link browser behavior (in chrome @ least) unless click link second time. know what's this?

trigger doesn't click on a, launch listener. default behavior triggering, here can do. can check in event handler if click triggered , manually change page :

if(e.istrigger) window.location = this.href

or open in window :

if(e.istrigger) window.open(this.href, '_blank ')

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...
