后台管理项目中关于新增、编辑弹框使用的另一种展示形式
2026年4月20日 13:45
目前大家项目中使用的弹框是以什么形式展现的呢？不知还记不记得以前在使用layui时，使用的layer.open中的iframe形式的弹框。本文编写的就是复刻这一形式的弹框类型，感兴趣的话可以接着往下看哦。
业务背景：目前公司写的大多数页面是这种弹框的类型(都是基于一个老项目的vue2.0版本的模板开发，还有引入jQuery)，弹框是基于layer.open二次封装实现的，所以后面我就自己仿照写了一个简易版本直接引入的，去掉不必要的依赖。
废话不多说直接上效果图！
可以全屏及拖动。目前我感觉比较麻烦的是需要维护更多的路由
代码展示：
在main.js中全局引入
页面使用： 列表页面中的新增及编辑按钮
// 新增及编辑按钮
const handleAdd = (row) => {
openDialog(
{
title: row? "编辑" : "新增",
path: "/#/testPageadd",
width: "800px",
height: "600px",
fullscreen: true,
drag: true,
close: true,
},
(res) => {
console.log(res, "resres");
},
);
};
新增testPageadd页面中回调事件：
//取消
const handleClose = (res) => {
closeDialog();
};
//确定
const handleSubmit = async () => {
closeDialog({ valid: true });
};
openDialog完整代码：
!(function (W) {
("use strict");
const keyframes = `.zDialog{display: inline-block;box-sizing: border-box;border-radius: 6px;}
@keyframes zcentre_in {
0% {
opacity: 0;
transform: scale(0);
-webkit-transform: scale(0);
-moz-transform: scale(0);
-ms-transform: scale(0);
-o-transform: scale(0);
}100% {
opacity: 1;
transform: scale(1);
-webkit-transform: scale(1);
-moz-transform: scale(1);
-ms-transform: scale(1);
-o-transform: scale(1);
}
}
@keyframes zcentre_out {
0% {
opacity: 1;
transform: scale(1);
-webkit-transform: scale(1);
-moz-transform: scale(1);
-ms-transform: scale(1);
-o-transform: scale(1);
}100% {
opacity: 0;
transform: scale(0);
-webkit-transform: scale(0);
-moz-transform: scale(0);
-ms-transform: scale(0);
-o-transform: scale(0);
display:none
}
}`;
// 创建style标签
const stylekeyframes = document.createElement("style");
// 设置style属性
stylekeyframes.type = "text/css";
// 将 keyframes样式写入style内
stylekeyframes.innerHTML = keyframes;
// 将style样式存放到head标签
document.head.appendChild(stylekeyframes);
// 样式合集
let style = {
Dialog: `position: fixed;top: 0;left: 0;height: 100vh;width: 100vw;overflow: hidden;`, // 主体样式
