找到的最简单的实现vue大屏开发的方式，页面按照1920px1080px正常开发，所有宽高写死，然后在大屏的页面添加如下代码：
原理是通过计算屏幕实际大小和19201080的比例，按照比例缩放页面大小。
1.在大屏的data里定义
screenWidth: null,
screenHeight: null,
- 在大屏的mounted里定义
// 监控屏幕尺寸变化
var bodyStyle = document.createElement("style");
// 这里根据具体的设计稿尺寸来定
bodyStyle.innerHTML = `body{width:1920px; height:1080px!important;}`;
document.documentElement.firstElementChild.appendChild(bodyStyle);
this.screenWidth = document.body.clientWidth;
this.screenHeight = document.body.clientHeight;
window.onresize = () => {
return (() => {
this.screenWidth = document.documentElement.clientWidth;
this.screenHeight = document.documentElement.clientHeight;
})();
};
document.addEventListener('keydown', (e)=>{
if(e.code == 'F11'){
this.screenWidth = document.documentElement.clientWidth;
this.screenHeight = document.documentElement.clientHeight;
}
})
- 在watch你监听
watch: {
screenWidth: {
handler: function () {
// console.log("val", val);
let docWidth = document.documentElement.clientWidth;
let docHeight = document.documentElement.clientHeight;
var designWidth = 1920, // 这里根据具体的设计稿尺寸来定
designHeight = 1080, // 这里根据具体的设计稿尺寸来定
widthRatio = docWidth / designWidth,
heightRatio = docHeight / designHeight;
document.body.style = `transform:scale(${widthRatio},${heightRatio});transform-origin:left top;overflow: hidden;`;
// 应对浏览器全屏切换前后窗口因短暂滚动条问题出现未占满情况
setTimeout(function () {
var lateWidth = document.documentElement.clientWidth,
lateHeight = document.documentElement.clientHeight;
if (lateWidth === docWidth) return;
widthRatio = lateWidth / designWidth;
heightRatio = lateHeight / designHeight;
document.body.style =
"transform:scale(" +
widthRatio +
"," +
heightRatio +
");transform-origin:left top;overflow: hidden;";
}, 0);
},
immediate: true,
deep: true,
},
screenHeight: {
handler: function () {
// console.log("val", val);
let docWidth = document.documentElement.clientWidth;
let docHeight = document.documentElement.clientHeight;
var designWidth = 1920, // 这里根据具体的设计稿尺寸来定
designHeight = 1080, // 这里根据具体的设计稿尺寸来定
widthRatio = docWidth / designWidth,
heightRatio = docHeight / designHeight;
document.body.style = `transform:scale(${widthRatio},${heightRatio});transform-origin:left top;overflow: hidden;`;
// 应对浏览器全屏切换前后窗口因短暂滚动条问题出现未占满情况
setTimeout(function () {
var lateWidth = document.documentElement.clientWidth,
lateHeight = document.documentElement.clientHeight;
if (lateWidth === docWidth) return;
widthRatio = lateWidth / designWidth;
heightRatio = lateHeight / designHeight;
document.body.style =
"transform:scale(" +
widthRatio +
"," +
heightRatio +
");transform-origin:left top;overflow: hidden;";
}, 0);
},
immediate: true,
deep: true,
},
},
