主要分界面与逻辑两大块css
界面分为5个部分vue
逻辑git
this.rangeWidth = document.body.clientWidth
@touchstart.stop.prevent="leftTextTouchStart" //按下 @touchmove.stop.prevent="leftTextTouchMove" //滑动 @touchend.stop.prevent="leftTextTouchEnd" //松开//右滑块,同上 @touchstart.stop.prevent="rightTextTouchStart" @touchmove.stop.prevent="rightTextTouchMove" @touchend.stop.prevent="rightTextTouchEnd"
//滑动事件方法 leftTextTouchStart() { this.leftClick = true; }, leftTextTouchEnd() { this.leftClick = false; }, //类样式绑定 :class="{check_text_div:leftClick}"
rangeWidth //整个容器的宽度 leftWidth //左边滑动的距离,经过滑动事件定义 rightWidth //右边滑动的距离,经过滑动事件定义 width() { return Math.min(Math.max(0, this.rangeWidth - this.leftWidth - this.rightWidth), this.rangeWidth)//内容宽度应等于总宽度减去左右两边,且大于等于0小于等于总宽度 } left() { return Math.max(this.leftWidth, 0)//防止左滑出界面 } right() { if (this.left + this.rightWidth <= this.rangeWidth) return Math.max(this.rightWidth - 0.5, 0)//防止右滑出界面 }
leftTextTouchMove(e) { let touch = e.changedTouches[0]; let clientX = touch.clientX;//获取滑动事件的横坐标值 if (clientX >= 0) {//只检测滑块在坐标值在屏幕内 if (this.left + this.right <= this.rangeWidth) {//防止左右滑块位置倒置 this.leftWidth = clientX;//左滑块距离等于x坐标 //界面操做 $('#nowRange').css({'left': this.left, 'width': this.width}); $('#leftText').css({'left': this.left}); $('#leftImg').css({'left': this.left}); } } } rightTextTouchMove(e) { let touch = e.changedTouches[0]; let clientX = touch.clientX;//获取滑动事件的横坐标值 if (clientX <= this.rangeWidth) {//只检测滑块在坐标值在屏幕内 this.rightWidth = this.rangeWidth - clientX;//右边滑块距离等于总长度减去滑动横坐标 if (this.left + this.right <= this.rangeWidth) {//防止左右滑块位置倒置 //界面变化 $('#nowRange').css({'width': this.width}); $('#rightText').css({'right': this.right}); $('#rightImg').css({'right': this.right}); } } },
6.文本内容经过计算值即可实现github
leftText() { let num = parseInt(this.left / this.rangeWidth * 100); if (num === 0 || isNaN(num)) return '不限'; return num + 'k'; } rightText() { if (this.rangeWidth === 0) return '不限'; let num = parseInt((this.rangeWidth - this.right) / this.rangeWidth * 100); if (num >= 0) { if (num === 100) return '不限'; return num + 'k'; } }
