获取复选框值并检查它们是否在数组中

<input type="checkbox" id="checkbox1" value="value1"> Option 1
<input type="checkbox" id="checkbox2" value="value2"> Option 2
<input type="checkbox" id="checkbox3" value="value3"> Option 3

// 获取复选框元素
var checkbox1 = document.getElementById("checkbox1");
var checkbox2 = document.getElementById("checkbox2");
var checkbox3 = document.getElementById("checkbox3");

// 创建数组
var array = ["value1", "value2", "value3"];

// 检查复选框是否被选中并在数组中
if (checkbox1.checked && array.includes(checkbox1.value)) {
    console.log("Checkbox 1 is checked and its value is in the array.");
}

if (checkbox2.checked && array.includes(checkbox2.value)) {
    console.log("Checkbox 2 is checked and its value is in the array.");
}

if (checkbox3.checked && array.includes(checkbox3.value)) {
    console.log("Checkbox 3 is checked and its value is in the array.");
}
