如何在选择列表框中的选项后将焦点移动到另一个div？

var selectBox = document.getElementById("selectBox");
selectBox.addEventListener("change", function() {
    // 在选项改变时执行以下代码
});

var selectedOption = selectBox.value;

var targetDiv;
switch (selectedOption) {
    case "option1":
        targetDiv = document.getElementById("div1");
        break;
    case "option2":
        targetDiv = document.getElementById("div2");
        break;
    // 添加更多选项的处理逻辑
}

targetDiv.focus();

var selectBox = document.getElementById("selectBox");
selectBox.addEventListener("change", function() {
    var selectedOption = selectBox.value;
    var targetDiv;
    switch (selectedOption) {
        case "option1":
            targetDiv = document.getElementById("div1");
            break;
        case "option2":
            targetDiv = document.getElementById("div2");
            break;
        // 添加更多选项的处理逻辑
    }
    targetDiv.focus();
});
