本文实例为大家分享了vue分割面板封装实现的具体代码,供大家参考,具体内容如下
记录一次 分割面板的封装:
<template>
<div class="split-pane-wrapper" ref="outer">
<div class="pane pane-left" :style="{ width: leftOffsetPercent }">
<slot name="left"></slot>
</div>
<div
class="pane-trigger-con"
@mousedown="handleMousedown"
:style="{ left: triggerLeft, width: `${triggerWidth}px` }"
>
//中间分割按钮
<div class="pane-trigger-con__button">
<div v-for="i in 10" :key="i"></div>
</div>
</div>
<div class="pane pane-right" :style="{ left: leftOffsetPercent }">
<slot name="right"></slot>
</div>
</div>
</template>
<script>
export default {
name: "SplitPane",
props: {
//分割值
value: {
type: Number,
default: 0.5,
},
//按钮宽度
triggerWidth: {
type: Number,
default: 8,
},
//最大分割值/最小分割值
min: {
type: Number,
default: 0.1,
},
max: {
type: Number,
default: 0.9,
},
},
data() {
return {
// leftOffset: 0.3,
canMove: false,
initOffset: 0,
};
},
computed: {
//计算左边面板的宽度
leftOffsetPercent() {
return `${this.value * 100}%`;
},
//右边面板的marginleft
triggerLeft() {
return `calc(${this.value * 100}% - ${this.triggerWidth / 2}px)`;
},
},
methods: {
//鼠标点击 鼠标移动事件 计算偏差
handleMousedown(event) {
document.addEventListener("mousemove", this.handleMousemove);
document.addEventListener("mouseup", this.handleMouseup);
this.initOffset =
event.pageX - event.class="lazy" data-srcElement.getBoundingClientRect().left;
this.canMove = true;
},
//鼠标移动事件 计算移动距离
handleMousemove(event) {
if (!this.canMove) return;
const outerRect = this.$refs.outer.getBoundingClientRect();
let offsetPercent =
(event.pageX -
this.initOffset +
this.triggerWidth / 2 -
outerRect.left) /
outerRect.width;
if (offsetPercent < this.min) offsetPercent = this.min;
if (offsetPercent > this.max) offsetPercent = this.max;
// this.$emit('input', offsetPercent)
this.$emit("update:value", offsetPercent);
},
handleMouseup() {
this.canMove = false;
},
},
};
</script>
<style lang="scss">
.split-pane-wrapper {
height: 100%;
width: 100%;
position: relative;
.pane {
position: absolute;
top: 0;
height: 100%;
&-left {
background: transparent;
padding: 10px;
box-sizing: border-box;
}
&-right {
box-sizing: border-box;
right: 0;
bottom: 0;
background: transparent;
padding: 10px;
}
&-trigger-con {
height: 100%;
background: rgb(240, 240, 240);
position: absolute;
top: 0;
z-index: 10;
user-select: none;
cursor: col-resize;
.pane-trigger-con__button {
border: 1px solid lightgrey;
width: calc(100% - 2px);
height: 20px;
margin: 0 auto;
position: relative;
top: 50%;
transform: translateY(-50%);
border-radius: 2px;
div {
margin: 1px 0;
width: 100%;
height: 1px;
background-color: lightgrey;
}
}
}
}
}
</style>
页面使用split-pane:
<div class="split-pane-con">
<split-pane :value.sync="offset">
<div slot="left"><el-input></el-input></div>
<div slot="right"><el-input></el-input></div>
</split-pane>
</div>
data() {
return {
offset: 0.4,
};
},
效果:
