javascript - How to enact styles with React.js -


i trying use inline styles react.js, keep running errors:

in render function, have:

render: function() {     var style = this.state.submitted ? {{"backgroundcolor": "#1abc9c", "opacity": "0.6"}} : {{}};      return (       <div>          <h1 classname="home-two-question" style={style}>{text}</h1>        </div>     )   },

basically want toggle style on click. however, when run this, error react.js. correct syntax inline styles in react.js? thank you!

in line:

var style = this.state.submitted ? {{"backgroundcolor": "#1abc9c", "opacity": "0.6"}} : {{}};

you're in plain javascript, not inside of jsx tag. thus, want use single {}, not double {{}}:

var style = this.state.submitted ? {"backgroundcolor": "#1abc9c", "opacity": "0.6"} : {};

in particular, when like:

<div style={{"backgroundcolor": "white"}}>

there 1 set of {} denote value of style prop should interpreted javascript, , set of {} denote constructing object within value.
