javascript - google maps map under materialize tab -


i tried create site looks fast changing content dynamically, use tab system form materialize, works great, except google maps map generate via api shows blank window: map

it shows map when resize window or if page active, active isn't solution!

thanks in advance possible solutions/fixes

i created jsfiddle showcase it: https://jsfiddle.net/8ajob4ja/

html:

<div class="row">      <div class="col s12">        <ul class="tabs">          <li class="tab col s6"><a href="#test1">test 1</a></li>          <li class="tab col s6"><a href="#test2" class="active">test 2</a></li> </ul>       </div>       <div id="test1" class="col s12">                <h3>my google maps demo</h3>     <div id="map"></div>     <!-- replace value of key parameter own api key. -->     <script async defer src="https://maps.googleapis.com/maps/api/js?key=aizasyckuodz5y7hmm0yrccqocvlwzdm6m8s5qk&callback=initmap">     </script>       </div>       <div id="test2" class="col s12">         2       </div>     </div>

js:

function initmap() {   var uluru = {lat: -25.363, lng: 131.044};   var map = new google.maps.map(document.getelementbyid('map'), {     zoom: 4,     center: uluru   });   var marker = new google.maps.marker({     position: uluru,     map: map   }); }

css:

#map {   height: 400px;   width: 100%;  }

please try code. because google directly calling initmap() when script execute @ time due reason map object not initialised reason need call initmap() way.

remove &callback=initmap js link below.

<script async defer src="https://maps.googleapis.com/maps/api/js?key=aizasyckuodz5y7hmm0yrccqocvlwzdm6m8s5qk"> </script>

add class in tab.

<li class="tab col s6 test"><a href="#test1">test 1</a></li>

replace jquery code.

$(".test").click(function () {initmap();});  function initmap() {   var uluru = {lat: -25.363, lng: 131.044};   var map = new google.maps.map(document.getelementbyid('map'), {     zoom: 4,     center: uluru   });   var marker = new google.maps.marker({     position: uluru,     map: map   }); }

hope helps.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
