I was trying to change background image style dynamically for the following div:
Here is my component for changing it,
render: function() {
var divImage = {
backgroundImage : "url(" + this.state.song.imgSrc + "),url(" + this.state.nextImgSrc + ");"
};
return (
<li>
<div ref="image-pane" className="player" style={divImage}></div>
</li>
)
}
Thanks for the help
You haven't specified when would you like to change backgroundImage
, so I've created version which changes it with onClick
:
React.createClass({
getInitialState: function () {
nextImg: false,
},
handleClick: function () {
this.setState({ nextImg: !this.state.nextImg })
},
render: function() {
var imgUrl = this.state.nextImg ? this.state.nextImgSrc : this.state.song.imgSrc;
var divStyle = {
backgroundImage: 'url(' + imgUrl + ')'
}
return (
<li>
<div ref="image-pane" style={divStyle} onClick={this.handleClick} className="player"></div>
</li>
)
}
});
Notice that backgroundImage: 'url(' + imgUrl + ')'
no longer must have trailing semicolon, in fact the trailing semicolon will cause React to raise and error.
This is caused by the trailing semicolon in your style. See react issues #2862.
