一个手写的vue放大镜效果

let truth = this.$refs.truth;
let virtual = this.$refs.virtual;
let bigPic = this.$refs.bigPic;
x = x-this.computedOffset(truth,'offsetLeft') -mask.offsetWidth/2;
y = y-this.computedOffset(truth,'offsetTop')- mask.offsetHeight/2;
if(x<=0) {
x=0
}else if(x>truth.offsetWidth - mask.offsetWidth){
x = truth.offsetWidth/2
}
if(y<=0){
y=0;
}
else if(y>truth.offsetHeight - mask.offsetHeight){
y = truth.offsetHeight/2
}

this.maskPosition = {
x,y
}
//计算比例
this.percent={
x:-x/(truth.offsetWidth-mask.offsetWidth)*(bigPic.offsetWidth - virtual.offsetWidth)+'px',
y:-y/(truth.offsetHeight-mask.offsetHeight)*(bigPic.offsetHeight - virtual.offsetHeight)+'px'
}
},
move(e){
this.computePosition(e)
}
}
}

CSS:

<style lang="less" scoped>
.now{
 border-color: cyan !important;
}
 .mirror{
  width:100%;

    }
    .virtual{
     overflow:hidden;
     width:100%;
     height:100%;
     position:absolute;
     left:calc(100% + 10px);
     top:0;
     background-repeat:no-repeat
    }
    .mask{
     position: absolute;
     background-image: url('https://img-tmdetail.alicdn.com/tps/i4/T12pdtXaldXXXXXXXX-2-2.png');
