我试图在React中创建一个滑块。
我的组件如下:
outterDivStyles() {
return {
position: "relative",
width: "100%",
overflow: "hidden",
height: this.props.height || 200
}
}
innerDivStyles(){
return {
position: "absolute",
top: 0,
left: this.state.left,
right: 0,
width: "1000%",
transition: "left .5s",
transitionTimingFunction: "ease"
}
}
renderArrows(){
return (
<div className="next-prev" style={{height: this.props.height || 200}}>
<div onClick={this.prevSlide.bind(this)}><img src={images.slider_arrow_left_png} /></div>
<div onClick={this.nextSlide.bind(this)}><img src={images.slider_arrow_right_png} /></div>
</div>
)
}
render(){
return(
<div>
<div ref="detailsOutterDiv" className="detailsOutterDiv" style={this.outterDivStyles()}>
<div ref="detailsInnerDiv" className="detailsInnerDiv" style={this.innerDivStyles()}>
{this.carInfo().photos.map((p, i) => {
return (
<div key={i} className="slide"><img src={p.image_url}/></div>
);
})}
</div>
{this.renderArrows()}
</div>
</div>
)
}
css如下:
.slide{
margin-right: 15px;
display: inline-block;
}
.slide img{
width: 100%;
height: auto;
}
@media (min-width: 1599px) {
.detailsOutterDiv .detailsInnerDiv div{
width: (10% / 3);
}
}
现在我试图通过课程slide
获得div的宽度加上边距。
我尝试用:
let slideWidth = this.refs["detailsInnerDiv"].childNodes[0].style.marginRight;
但slideWidth
为0。
有什么建议吗?
答案 0 :(得分:2)
试试这个。
let node = this.refs["detailsInnerDiv"].childNodes[0] //assuming this as your target node
let nodeStyle = window.getComputedStyle(node)
let slideMarginRight = nodeStyle.getPropertyValue('margin-right')

希望这有帮助!
