javascript - ReferenceError: Can't find variable: require - JQuery error -


i use code in .js file part of web site used via npm global http-server:

function getparsedstorage() {   let fs = require('fs');   return json.parse(fs.readfilesync('./../manager-data.json', 'utf8')); }

and errors:

jquery.deferred exception: can't find variable: require (2) (exceptionhook — jquery.min.js:2:31584)

referenceerror: can't find variable: require (jquery.min.js:2:31697)

i've installed file-system package npm install file-system --save didn't change anything.

it looks me you're attempting make use of node.js's require function within web browser without using module system provides compatible require method.

without additional information can't certain, advice investigate module loader require.js, systemjs or browserify should enable make use of syntax in module.

that being said, use case you're describing (accessing json file website) may better served using simple xhrhttprequest or fetch api.

the following example makes use of fetch api return parsed json file content.

// returns promise resolves parsed storage data // note: lacks error handling function getparsedstorage() {   return fetch("../manager-data.json").then(response => response.json()) }

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
