使用vue-drag-resize做拖拽功能,放大缩小后,如何使vue-drag-resize跟着放大缩小?
需求,页面上有一个矩形,需要可以拖拽移动,且放大缩小,拖拽功能想到了使用组件vue-drag-resize
,将放大缩小(不是改变矩形的大小)使用的css属性transform: scale()
,但是通过css放大缩小矩形后,发现vue-drag-resize
并没有跟着放大缩小,举行线条还是初始化的小大状态,该如何解决?
代码如下:
<template> <div class="content-body">
<div class="slider">
<el-slider v-model="scale" height="150px" :max="2.0" :step="0.1" :min="0.1"></el-slider>
</div>
<div class="content-inner-body">
<vue-drag-resize
style="position: absolute;"
:parentScaleX='scale'
:parentScaleY='scale'
class="drag-item"
:isActive="true"
:w="sizeObj.width"
:h="sizeObj.height"
:z="3"
:isDraggable='true'
:isResizable="false"
:preventActiveBehavior='true'
v-on:dragging="onDragging"
>
<div class="lines-wrapper" :style="[{transform: `scale(${scale})`}, {width: `${sizeObj.width}`, height: `${sizeObj.height}`}]">
</div>
</vue-drag-resize>
</div>
</div>
</template>
<script>
export default {
computed: {
},
mounted() {
},
data() {
return {
scale: 1,
sizeObj: {
x: 0,
y: 0,
width: 600,
height: 400
}
}
},
methods: {
onDragging(newRect) {
this.sizeObj.x = newRect.top;
this.sizeObj.y = newRect.left;
this.sizeObj.width = newRect.width;
this.sizeObj.height = newRect.height;
},
},
}
</script>
<style lang="scss" scoped>
.content-body{
position: relative;
width: 100%;
height: 100%;
overflow: hidden;
background: rgba($color: #000000, $alpha: 0.1);
.slider{
position: absolute;
bottom: 10px;
right: 30px;
width: 150px;
}
.content-inner-body{
position: absolute;
background: rgba($color: #000000, $alpha: 0.3);
overflow: hidden;
top: 30px;
right: 30px;
bottom: 30px;
left: 30px;
padding: 20px;
box-sizing: border-box;
.lines-wrapper{
position: relative;
transform-origin: left top;
width: 100%;
height: 100%;
background: #fff;
}
}
}
</style>
效果如下图:
回答:
<el-slider v-model="scale" @change="resizeDragItem"></el-slider>...
methods: {
resizeDragItem() {
this.sizeObj.width *= this.scale;
this.sizeObj.height *= this.scale;
},
...
}
