如何利用vuejs指令实现不同分辨率适配?下面web建站小编给大家详细介绍一下实现代码!
兼容不同分辨率适配代码
// 缩放指令 import Vue from "vue"; function transformScale(el, options) { const { target = "width", origin = "top left" } = options; Vue.nextTick(() => { // 获取显示区域高宽 const width = window.innerWidth; const height = window.innerHeight; el.style.transformOrigin = origin; if (target === "ratio") { const scaleX = width / CONF.width; const scaleY = height / CONF.height; el.style.transform = `scaleX(${scaleX}) scaleY(${scaleY})`; } else { let scaleProportion = 1; if (target === "width") { scaleProportion = width / CONF.width; } if (target === "height") { scaleProportion = height / CONF.height; } el.style.transform = `scale(${scaleProportion})`; } }); } function inserted(el, binding) { const options = binding.options || { passive: true }; const callback = () => transformScale(el, binding.value); window.addEventListener("resize", callback); callback(); el._onResize = { callback, options }; } function unbind(el) { if (!el._onResize) { return; } const { callback } = el._onResize; window.removeEventListener("resize", callback); delete el._onResize; } export const Scale = { inserted, unbind }; export default Scale;
