当当网站开发论文seo是什么服务

效果如下gif

只进行了基础的事件和布局，可优化的地方：luminance-box这个div加上后，由于和slider-run-way都是absolute定位，导致slider-run-way的点击事件无法设置值，只能通过滑块设置。暂时想不到咋处理，有想法可以讨论一下

html布局

<div class="light-slider"><divclass="slider-run-way"@click.stop="handleClickRunway($event)"ref="runwayRef"><div class="active-bar" :style="{ width: activeWidth + '%' }"></div><divclass="control-wrapper":style="{ left: activeWidth + '%' }"@mousedown="handleMousedown($event)"><div class="control-btn"><span></span><span></span></div></div></div><div class="luminance-box" @click="handleRight"><img src="../../../../assets/home/homepage_control_bright.png" /><div class="right-box"><span class="num">{{ activeWidth }}%</span><span class="l-title">luminance</span></div></div></div>

js部分

export default {name: "lightingControl",props: {isDisabled: {type: Boolean,default: true,},},data() {return {activeWidth: 13,runWayWidth: 0, // 滑道总宽度startX: 0,dragging: false,isClick: true,startPosition: 0,};},mounted() {this.$nextTick(() => {this.runWayWidth = this.$refs.runwayRef.clientWidth;});},methods: {handleClickRunway(e) {if (!this.isClick || this.isDisabled) return;console.log(e);const { runWayWidth } = this;const { offsetX } = e;const percent = parseInt((offsetX / runWayWidth) * 100);this.activeWidth = percent;},handleRight(e) {return false;},handleMousedown(e) {if (this.isDisabled) return;e.preventDefault();this.startX = e.clientX;this.onDragStart(e);window.addEventListener("mousemove", this.onDragging);window.addEventListener("mouseup", this.onDragEnd);},onDragStart(e) {this.dragging = true;this.isClick = true;this.startPosition = parseFloat(this.activeWidth);},onDragging(e) {e.stopPropagation();if (this.dragging) {this.isClick = false;let currentX = e.clientX;let diff = ((currentX - this.startX) / this.runWayWidth) * 100;this.newPosition = this.startPosition + diff;this.setPosition(this.newPosition);}},onDragEnd() {if (this.dragging) {setTimeout(() => {this.dragging = false;if (!this.isClick) {this.setPosition(this.newPosition);this.isClick = true;}}, 0);window.removeEventListener("mousemove", this.onDragging);window.removeEventListener("mouseup", this.onDragEnd);}},setPosition(newPosition) {if (newPosition < 0) {newPosition = 0;} else if (newPosition > 100) {newPosition = 100;}this.activeWidth = Math.round(newPosition);},},
};
