reactjs - React - Cannot read property 'state' of undefined -


i keep getting error despite using fat arrow function bind context of when using setstate. can please help?

export default class app extends component {  constructor(props) {     super(props);     this.state = {         query: '',         items: [],         repos: []     }; }  search(term) {     this.setstate({         query: term     });     const clientid = '12489b7d9ed4251ebbca';     const secret = 'ff53ac9a93aaa9e7cddc0c009d6f068302866ff2';      function fetchuser() {         return axios.get(`https://api.github.com/users/${this.state.query}/repos?client_id=${clientid}client_secret=${secret}`);     }      function fetchrepos() {         return axios.get(`https://api.github.com/users/${this.state.query}?client_id=${clientid}client_secret=${secret}`);     }      axios.all([fetchuser(), fetchrepos()])         .then(axios.spread((items, repos) => {             this.setstate({                 items: items.data,                 repos: repos.data              });             console.log(state);         }));  }

from error message seems clear this undefined. because using in search() , search() isn't bound component, making this meaningless. fix try adding line @ end of constructor function:

        this.search = this.search.bind(this);

now should able use this in search function.

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...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
