uniapp修改html样式,关于css:uniapp操作dom改变css样式

在uniapp中,想给元素增加一些动静的css款式,例如transform,

uni.createSelectorQuery().select(“.sticke”).boundingClientRect((res)=>{

uni.createSelectorQuery().select(“.sticke”).style.transform

}).exec()

上述代码根本无法实现给元素增加transform,所以有了申明css变量,

在swiper组件中减少缩略图展现,点击某一项,展现到对应的图片

1.重点在data中注册属性transStyle

2.轮播change事件设置transStyle

getDetail(e,index){

this.currentIndex = index

this.detail = Object.assign(this.detail,e)

this.scrollLeft = index*50

this.transStyle = ‘translate(‘+index*-100+’%, 0px)’

},

3.点击缩略图,敞开自动播放,延时执行

move(e,index){

this.autoplay = false

this.currentIndex = index

this.detail = Object.assign(this.detail,e)

this.scrollLeft = index*50

this.transStyle = ‘translate(‘+index*-100+’%, 0px)’

setTimeout(()=>{

this.autoplay = true

},5000)

}

4.找到要扭转的元素,设置css变量

#swiper{

.uni-swiper-slide-frame{

transform: var(–transStyle) !important;

}

}
