<select id="select1">

  <option value="2">Option 2</option>
</select>

<select id="select2">
  <option value="3">Option 3</option>
  <option value="4">Option 4</option>
</select>

var select1 = document.getElementById("select1");
var select2 = document.getElementById("select2");

var selectedValue1 = select1.value;
var selectedValue2 = select2.value;

function getSelectedValues() {
  var selectIds = ["select1", "select2"]; // 存储select的ID值
  var selectedValues = {}; // 存储选中的值

  for (var i = 0; i < selectIds.length; i++) {
    var select = document.getElementById(selectIds[i]);
    selectedValues[selectIds[i]] = select.value;
  }

  return selectedValues;
}

var selectedValues = getSelectedValues();
console.log(selectedValues);
