angular - Using Pipes within ngModel on INPUT Elements in Angular2-View -


i've html input field.

<input [(ngmodel)]="item.value" name="inputfield" type="text" />

and want format value , use existing pipe:

.... [(ngmodel)]="item.value | usemypipetoformatthatvalue" .....

and error message:

cannot have pipe in action expression

how can use pipes in context?

you can't use template expression operators(pipe, save navigator) within template statement:

(ngmodelchange)="template statements"

(ngmodelchange)="item.value | usemypipetoformatthatvalue=$event"

https://angular.io/docs/ts/latest/guide/template-syntax.html#!#template-expressions

so should write follows:

<input [ngmodel]="item.value | usemypipetoformatthatvalue"        (ngmodelchange)="item.value=$event" name="inputfield" type="text" />

plunker example

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
