实现一：采用html编写弹出窗口内容

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        #dialog {
            position: absolute;
            z-index: 9999;
            top: 110px;
            left: 45%;
            transform: translate(-50%, -50%);
            width: 290px;
            height: 130px;
            background-color: #fff;
            border: 1px solid #ccc;
            box-shadow: 0 0 5px rgba(0, 0, 0, 0.3);
            border-radius: 5px;
            padding: 20px;
            display: none;
        }
        #dialog h3 {
            margin-top: 0;
        }
        #dialog div{
            margin-top: 15px;
        }
        #dialog button {
            margin-right: 10px;
            float: right;
        }
    </style>
</head>
<body>
<button onclick="showDialog()">弹出窗口</button>
<div id="dialog">
    <h3>导出数据</h3>
    <p>按页面条件导出数据还是导出所有的数据</p>
    <input type="radio" name="type" value="1" checked> 按页面条件导出
    <input type="radio" name="type" value="2"> 导出全部
    <div>
        <button onclick="hide()">取消</button>
        <button onclick="javascript:alert(22);">确定</button>
    </div>
</div>
<script>
    function show() {
        // 获取对话框元素并设置标题和消息
        let dialog = document.querySelector('#dialog');
        // 显示对话框
        dialog.style.display = 'block';
    }
    function hide() {
        // 获取对话框元素并隐藏
        let dialog = document.querySelector('#dialog');
        dialog.style.display = 'none';
    }
    function showDialog() {
        let dialog = document.querySelector('#dialog');
        dialog.querySelector('button').style.display = 'block';
        show('确认删除', '你确定要删除这条记录吗？');
    }
</script>
</body>
</html>

实现二：采用JavaScript编写弹出窗口内容

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        #dialog {
            position: absolute;
            z-index: 9999;
            top: 110px;
            left: 45%;
            transform: translate(-50%, -50%);
            width: 290px;
            height: 130px;
            background-color: #fff;
            border: 1px solid #ccc;
            box-shadow: 0 0 5px rgba(0, 0, 0, 0.3);
            border-radius: 5px;
            padding: 20px;
            display: none;
        }
        #dialog h3 {
            margin-top: 0;
        }
        #dialog div {
            margin-top: 15px;
        }
        #dialog button {
            margin-right: 10px;
            float: right;
        }
    </style>
</head>
<body>
<button onclick="showDialog('导出数据')">弹出窗口</button>
<script>
    function showDialog() {
        let dialogDiv = document.createElement("div");
        dialogDiv.id = "dialog";
        let h3Element = document.createElement("h3");
        h3Element.innerText = '导出数据';
        dialogDiv.appendChild(h3Element);
        let pElement = document.createElement("p");
        pElement.innerText = "按页面条件导出数据还是导出所有的数据";
        dialogDiv.appendChild(pElement);
        let div1 = document.createElement("div");
        let input1Element = document.createElement("input");
        input1Element.type = "radio";
        input1Element.name = "requestType";
        input1Element.checked=true;
        input1Element.value = 1;
        div1.appendChild(input1Element);
        let span1 = document.createElement("span");
        span1.innerText = "按页面条件导出";
        div1.appendChild(span1);
        let input2Element = document.createElement("input");
        input2Element.type = "radio";
        input2Element.name = "requestType";
        input2Element.value = 2;
        div1.appendChild(input2Element);
        let span2 = document.createElement("span");
        span2.innerText = "按页面条件导出";
        div1.appendChild(span2);
        dialogDiv.appendChild(div1);
        let div2 = document.createElement("div");
        let button1 = document.createElement("button");
        button1.addEventListener("click", function () {
            dialogDiv.style.display = 'none';
        });
        button1.innerText = "取消";
        div2.appendChild(button1);
        let button2 = document.createElement("button");
        button2.addEventListener("click", function () {
            let checkValue=1;
            let radioButtons = document.getElementsByName('requestType');
            for (let i = 0; i < radioButtons.length; i++) {
                if (radioButtons[i].checked) {
                    checkValue =  radioButtons[i].value;
                    break;
                }
            }
            alert(checkValue)
        });
        button2.innerText = "确定";
        div2.appendChild(button2);
        dialogDiv.appendChild(div2);
        document.body.appendChild(dialogDiv);
        // 显示对话框
        dialogDiv.style.display = 'block';
    }
</script>
</body>
</html>

实现三：抽取成独立的JS插件，在网页中使用

第一步：抽取出exportDialog.css：

#dialog {
    position: absolute;
    z-index: 9999;
    top: 110px;
    left: 45%;
    transform: translate(-50%, -50%);
    width: 290px;
    height: 130px;
    background-color: #fff;
    border: 1px solid #ccc;
    box-shadow: 0 0 5px rgba(0, 0, 0, 0.3);
    border-radius: 5px;
    padding: 20px;
    display: none;
}
#dialog h3 {
    margin-top: 0;
}
#dialog div {
    margin-top: 15px;
}
#dialog button {
    margin-right: 10px;
    float: right;
}

第二步；抽取出exportDialog.js：

/**
 *
 * @param url1  按页面条件导出
 * @param url2  导出全部数据
 */
function showDialog(url1,url2 ) {
    let dialogDiv = document.createElement("div");
    dialogDiv.id = "dialog";
    let h3Element = document.createElement("h3");
    h3Element.innerText = '导出数据';
    dialogDiv.appendChild(h3Element);
    let pElement = document.createElement("p");
    pElement.innerText = "按页面条件导出数据还是导出所有的数据";
    dialogDiv.appendChild(pElement);
    let div1 = document.createElement("div");
    let input1Element = document.createElement("input");
    input1Element.type = "radio";
    input1Element.name = "requestType";
    input1Element.checked=true;
    input1Element.value = 1;
    div1.appendChild(input1Element);
    let span1 = document.createElement("span");
    span1.innerText = "按页面条件导出";
    div1.appendChild(span1);
    let input2Element = document.createElement("input");
    input2Element.type = "radio";
    input2Element.name = "requestType";
    input2Element.value = 2;
    div1.appendChild(input2Element);
    let span2 = document.createElement("span");
    span2.innerText = "全部导出";
    div1.appendChild(span2);
    dialogDiv.appendChild(div1);
    let div2 = document.createElement("div");
    let button1 = document.createElement("button");
    button1.addEventListener("click", function () {
        dialogDiv.style.display = 'none';
    });
    button1.innerText = "取消";
    div2.appendChild(button1);
    let button2 = document.createElement("button");
    button2.addEventListener("click",function () {
        let checkValue=1;
        let radioButtons = document.getElementsByName('requestType');
        for (let i = 0; i < radioButtons.length; i++) {
            if (radioButtons[i].checked) {
                checkValue =  radioButtons[i].value;
                break;
            }
        }
        if(checkValue==1){
            //按页面条件导出
            document.location.href= url1
        }
        if(checkValue==2){
            //全部导出
            document.location.href= url2
        }
        //隐藏对话框
        dialogDiv.style.display = 'none';
    } );
    button2.innerText = "确定";
    div2.appendChild(button2);
    dialogDiv.appendChild(div2);
    document.body.appendChild(dialogDiv);
    // 显示对话框
    dialogDiv.style.display = 'block';
}

第三步：在页面中使用：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="stylesheet" href="/tiku/static/dialog/exportDialog.css" rel="external nofollow" ></link>
    <script src="/tiku/static/dialog/exportDialog.js"></script>
</head>
<body>
<button onclick="showDialog('/tiku/subject/export?state=1&pid=-2','/tiku/subject/export?pid=-2')">弹出窗口</button>
<script>
</script>
</body>
</html>
