javascript - Embedded Youtube videos not playing in mobile iOS Safari -


recently we've found bug exists only in safari on iphone(s) cannot pinpoint source of issue. when pressing play button video appears load closes immediately.

all answers i've found far aren't recent and/or don't solve problem. testing in browserstack giving me error: invalid css property declaration at: * www-embed-player-sprite-mode-vfl9mhoab.css file served youtube.

i'm open optional ways of handling embedded videos avoid issue.

the code:

#set($showvideo = $request.getparameter("showvideo")) #set($howitworksid = $placeholder.getattributevaluegroup().getattributevalue('product_howitworks', $sesshoppingcart.getlocale())) #set($embeddedurl = "https://www.youtube.com/embed/" + $howitworksid + "?rel=0") #set($hasvideoid = false) #if( $howitworksid && $howitworksid != "" )     #set( $hasvideoid = true ) #end  <div id="howitworksmodal" class="modal-howitworks modal fade">   <div class="modal-dialog modal-lg">     <div class="modal-content">         <button type="button" class="close js-modalclose close--howitworks" data-dismiss="modal">             <span aria-hidden="true">&times;</span>             <span class="sr-only">close</span>         </button>         <div>             <div class="prose howitworks-embedvideowrapper">               <div class="iframe-container">                     <iframe id="howitworks-modalversion" class="howitworks js-howitworks-iframe" width="100%" src="" frameborder="0" allowfullscreen preload></iframe>               </div>            </div>         </div>      </div>   </div> </div>      jqueryready(function() {              var videourl = "$embeddedurl";              // load destination video , autoplay when modal opens             $("#howitworksmodal").on('shown.bs.modal', function(ev) {                 ev.preventdefault();                 $("#howitworks-modalversion").attr("src", videourl + "&autoplay=1");                 console.log('clicked on');             });              // kill video when modal closed             $('#howitworksmodal').on('hidden.bs.modal', function (e) {                 $('.js-howitworks-iframe').each( function(){                     $(this).attr('src', '');                 });             });              // kill mobile video if playing while window resized             function mobilevideosource(){                 var mobileblock = $('#buynow-mobileblock'),                     howtovid_mobile = $('#howitworks-mobileversion');                  if (mobileblock.is(":hidden")) {                     // if mobile block hidden remove it's source                     howtovid_mobile.attr('src', '');                 } else {                     // if mobile block displayed add source                     howtovid_mobile.attr('src', videourl);                 }             }              sdi.window.on('resize', mobilevideosource);         })

mobilevideosource() being called , removing src when video opening. did not investigate why happening, restructured script remove iframe instead of src , inject new instance if (for whatever rare edge use case) screen resized down mobile , user wants watch video again:

function mobilevideosource() {   var mobileblock  = $('#buynow-mobileblock'),   currentvid     = $('#howitworks-mobileversion'),   videocontainer = $('.iframe-container')   new_iframe     = $('<iframe id="howitworks-mobileversion" class="howitworks" width="560" height="315" src="$embeddedurl" frameborder="0" allowfullscreen></iframe>');      if (mobileblock.is(":hidden")) {       currentvid.remove();     } else {       videocontainer.append(new_iframe);     }  }

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
