如何获取按钮事件的标签信息

<button id="myButton" data-tag="标签信息">点击按钮</button>

<script>
    const button = document.getElementById("myButton");
    button.addEventListener("click", function() {
        const tag = button.getAttribute("data-tag");
        console.log(tag); // 输出：标签信息
    });
</script>

<button id="myButton">点击按钮</button>

<script>
    const button = document.getElementById("myButton");
    button.addEventListener("click", function(event) {
        const tag = event.target.getAttribute("data-tag"); // 按钮自身的属性
        // 或者 const tag = event.currentTarget.getAttribute("data-tag"); // 按钮父元素的属性
        console.log(tag); // 输出：标签信息
    });
</script>

<button id="myButton">点击按钮</button>

<script>
    function createButtonHandler(tag) {
        return function() {
            console.log(tag); // 输出：标签信息
        };
    }
    
    const button = document.getElementById("myButton");
    const tag = "标签信息";
    button.addEventListener("click", createButtonHandler(tag));
</script>
