需要在列表框中正确显示数组的帮助

var array = ["选项1", "选项2", "选项3"];
var select = document.getElementById("mySelect");

for (var i = 0; i < array.length; i++) {
  var option = document.createElement("option");
  option.text = array[i];
  select.add(option);
}

var array = ["选项1", "选项2", "选项3"];
var select = document.getElementById("mySelect");

array.map(function(item) {
  var option = document.createElement("option");
  option.text = item;
  select.add(option);
});

<div id="app">
  <select v-model="selectedOption">
    <option v-for="option in options" :value="option">{{ option }}</option>
  </select>
</div>

<script>
new Vue({
  el: "#app",
  data: {
    selectedOption: "",
    options: ["选项1", "选项2", "选项3"]
  }
});
</script>
