1. Share the code

Html code

A very simple structure, after all, is only a DEMO

SCSS code

.main {background-color: brown; height:-webkit-fill-available; .drag _ area {width: 10vW; height: 10vW; background-color: dodgerblue; position: absolute; top: 0; left: 0;}}

In order to take a screenshot to stand out, I specially added a background color to main.

Effect picture

The effect is that you can drag the blue color block freely within the scope of the screen, but beyond the screen area I have specially made a limit, and you can change it yourself if you don't need to limit it.

JS code

Export default {name: 'drag', data () {return {flags: false, position: {x: 0, y: 0, left: 0, top: 0}, top: 0, left: 0, width: window.innerWidth | | document.documentElement.clientWidth | | document.body.clientWidth, height: window.innerHeight | | document.documentElement.clientHeight | | document.body.clientHeight}} Methods: {down () {/ / drag the operation this.flags = true const refs = this.$refs.move_div.getBoundingClientRect () let touch = event if (event.touches) {touch = event.touches [0]} this.position.x = touch.clientX this.position.y = touch.clientY this.position.left = refs.left this.position.top = refs.top} Operation in move () {/ / drag if (this.flags) {let touch = event if (event.touches) {touch = event.touches [0]} const xPum = this.position.left + touch.clientX-this.position.x const yPum = this.position.top + touch.clientY-this.position.y this.left = xPum this .top = yPum this.banOut () / / prevent the page from sliding the default event document.addEventListener ('touchmove' Function () {event.preventDefault ()}, {passive: false}, end () {/ / drag the end operation this.flags = false this.banOut ()}, banOut () {/ / avoid dragging out-of-bounds restrictions const refs = this.$refs.move_div.getBoundingClientRect () if (this.left)
