javascript - How to manipulate HTML element styles in aurelia-router postRender step -


i make aurelia application footer height dynamic, tried use aurelia-router postrender step following aurelia hub documentation.

here way tried achieve it, app.js code:

export class app {   configurerouter(config, router) {     config.title = 'aurelia';     var step = {       run: (navigationinstruction, next) => {         $('.page-host').css('padding-bottom', $('#footer').outerheight() + 'px');         return next();       }     };     config.addpostrenderstep(step);     config.map([       { route: ['', 'welcome'], name: 'welcome', moduleid: 'views/welcome', nav: false, title: 'welcome' }     ]);      this.router = router;   } }

and here app.html markup:

<template>   <require from="global/nav-bar.html"></require>   <require from="global/footer-bar.html"></require>   <require from="styles/style.css"></require>    <nav-bar></nav-bar>    <div class="page-host">     <router-view></router-view>      <footer-bar></footer-bar>   </div> </template>

in addition <footer-bar></footer-bar> contains footer#footer element.

what missing?

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
