javascript - AngularJS duplicated element for 1 second -


i have login form contains box display error message

<div class="ui negative message" ng-if="vm.message != ''">     <span ng-bind="vm.message"></span> </div>

the message set inside controller

loginservice.checkuser(vm.credentials).then(function(res) {     $rootscope.token = res.data.token;     $state.go('home'); }, function(err) {     vm.error = true;     if(err.status == 401){         vm.message = "error !";     } });

my problem div containing message shown 2 times during 1sec after clicking on login button. during 0.5/1 second have 2 times same div same message.

user cannot see says can see blinking.

how can avoid getting blink ?

your ng-if doesn't work in html, change this:

<div class="ui negative message" ng-if="vm.message">   <span ng-bind="message"></span> </div>

the statement ng-if="vm.message != ''" did not hide element causes blinking. can declare vm-message = null in controller when it's loaded make sure.

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

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
