javascript - How would you call specific CSS stylesheet in a React component on a specific site? -


so i'm working on platform built on react , platform has global css set clients way.

a subset of affiliates under common group name want new sticky ad component has change css bit footer not covered up.

so normally, i'd check our global variable value is, window.client.group, , if it's group, add css or css stylesheet through javascript in affiliate js file (our old generic platform).

the new css needed is:

  @media (max-width:767px){     #ad201 {width:100%;position:fixed;bottom:0;left:0;z- index:99999;margin:0;border:1px solid rgb(232, 232, 232);background- color:#fff;margin: 0 !important;}     .footer .container {padding-bottom:50px;}   }

in react though, what's best , proper way this? can see it's complicated needing in media query.

i have start using group , matchmedia, what's best way bring in css? whole stylesheet? (stickyad.css? other way? , tips on how it?)

const group = (window.client.group).tolowercase(); console.log(group);  const mq = window.matchmedia("(max-width: 767px)");  if ((mq.matches) && (group === 'premiere')) {   // bring in new css } else {   // nothing }

thanks advice !

it depends on how control have on ad201 , footer.

i'm assuming footer component you've created in react. in case, add class premiere-footer-fix (you can think of better name) components being rendered when detect group:

render() {   const group = (window.client.group).tolowercase();    return (     <footer classname={group === 'premiere' ? 'premiere-footer-fix' : ''}/>   ) }

or if import handy classnames package,

import classnames 'classnames';  // ...  render() {   const group = (window.client.group).tolowercase();   const classes = classnames({     'premiere-footer-fix': group === 'premiere'   });    return (     <footer classname={classes}/>   ) }

then wherever declare css footer, add like:

@media (max-width:767px) {     .footer.premiere-footer-fix .container {       padding-bottom: 50px;     } }

as ad, you'd have provide more info how it's being inserted page since it's not clear how control have on element. add premiere ad's classlist , find place insert bit of css:

@media (max-width:767px) {   #ad201.premiere {     width: 100%;     position: fixed;     bottom: 0;     left: 0;     z-index: 99999;     margin: 0;     border: 1px solid rgb(232, 232, 232);     background-color: #fff;     margin: 0 !important;   } }

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
