javascript - 如何更改数组变量

Question

我有一个名为数据的变量数组，对于 IGcombobox 数据源，我想在单击#select 时更改数组，我该怎么做？使用此代码，它不会更改变量。我也可以只使用 php，但我不想那样做!

<div id="checkboxSelectCombo" name="kanal" style="position:absolute;" ></div>

<select id="seade" name="seade">        
  <?php for($i = 1; $i <= $devi; $i++) {
    echo '<option value="' . $i . '">' .$device_name[$i]. '</option>';
  } ?>
</select> 

$(function () {
  var data = [
    { ID: "1", Name: "Vooluandur 1" },
    { ID: "2", Name: "Meeter 1" }
  ];

  $("#seade").on('click', function(event) {
    console.log($("#seade").val());
    if ($("#seade").val() == 2) {
      var data = [
        { ID: "3", Name: "Vooluandur 2" },
        { ID: "4", Name: "Meeter 2" }
      ];
    }
  });

  $("#checkboxSelectCombo").igCombo({
    width: "100px",
    dataSource: data,
    textKey: "Name",
    valueKey: "ID",
    multiSelection: {
      enabled: true,
      showCheckboxes: true
    }
  });
});

你可以试试这个:(虽然没有运行它)

$("#seade").on('change', function(event) {
    if (this.value == 2) {
        data = [
            { ID: "3", Name: "Vooluandur 2" },
            { ID: "4", Name: "Meeter 2" }
        ];
    }
});
