javascript - Ionic Form Can't Change Option on Select -


i trying create form in ionic, including dropdown list. previously, had following code:

            <label class="item item-input item-select">                 <span class="input-label">* age</span>                 <select ng-model="data.child1.age" required>                     <option ng-value="7">year 7 (11-12)</option>                     <option ng-value="8">year 8 (12-13)</option>                     <option ng-value="9">year 9 (13-14)</option>                     <option ng-value="10">year 10 (14-15)</option>                     <option ng-value="11">year 11 (15-16)</option>                     <option ng-value="12">year 12 (16-17)</option>                     <option ng-value="13">year 13 (17-18)</option>                 </select>             </label>

the problem when loaded in saved data (from db), view not update match model.

so, after research, tried instead:

            <label class="item item-input item-select">                 <span class="input-label">* age</span>                 <select ng-model="data.child1.age" ng-options="item.id item.label item in ageoptions" required></select>             </label>

where ageoptions looks this:

             $scope.ageoptions = [                 {id: 7, label: "year 7 (11-12)"},                 {id: 8, label: "year 8 (12-13)"},                 {id: 9, label: "year 9 (13-14)"},                 {id: 10, label: "year 10 (14-15)"},                 {id: 11, label: "year 11 (15-16)"},                 {id: 12, label: "year 12 (16-17)"},                 {id: 13, label: "year 13 (17-18)"}              ]

however, although view updates fine , matches model, can't change selected option! more specifically, clicking on form element doesn't (ie open dropdown box).

i have looked around bit couldn't find on this. help!

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

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
