reactjs - Add custom HTML attributes with no value to JSX -


i have html needs custom attributes no value dependent on situation.. example these valid:

<div classname="playlist-row" selected> <div classname="playlist-row" active>    <div classname="playlist-row">

i tried doing like

let customattr = {'active'};  // incorrect syntax let customattr = {'active': true};  //doesn't work let customattr = {'active': ''};  //doesn't work  <div classname="playlist-row" {...customattr}>

any ideas of how can work?

i believe should - in render() function:

render() {     let customattr = "active"      return (         <div classname={"playlist-row " + customattr}>     ) }

or alternately, avoid string concatenation...

<div classname={`playlist-row ${customattr}`}>

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() .
