我有两个多选下拉菜单，它们都有相同的一组值。

如果您在第一个下拉列表中选择了一个选项，则在第二个下拉列表中将禁用该选项。

我可以针对第一个选项执行此操作，但不能针对后续选项执行此操作。

这可以通过相对选择器来完成。为此，我使用了一个option单击事件。然后我抓取另一个表单组并修改它。它是双向的，这意味着如果你从select A中选择，那么select B将被修改，反之亦然。

$("option").click(function () {
    $otherFormGroup = $(".form-group").not(
         $(this)
            .parents(".form-group:first")
    ); //grabs the other form group
    $otherFormGroup.find("option").attr("disabled", false); //resets all other banned items
    $otherFormGroup.find("option[value='"+$(this).attr("value")+"']")
        .attr("disabled",true); //disabled selected item in the other select area
});

前面的答案不适用于多个选择，我已经修改了代码以匹配多个选择

$(".form-group:first option").click(function () {
    var selecteds = $('option:selected', $(this).parent());
    $secondFormGroup = $(".form-group:eq(1)");
    $secondFormGroup.find("option").attr("disabled", false);
    selecteds.each(function (i, el) {
    		var id = this.id.substr(7);
        $('#inc_opt' + id).attr('disabled', true);
    });
});

在这两个select中，ID值在货币和冬季是相同的，我已经更改了它，并在脚本中将inc_id对象放入函数中。

$('#subject_to_id').on('change', function (e) {
      var optionSelected = $("option:selected", this);
      var idSelected = this.value;

      var idSelected = $(this).children(":selected").attr("id");
      var str = idSelected;

      //alert(str + " "+str.length)

      var inc_id = "#inc_" + str.substring(4, str.length);

      //alert(inc_id);
      $(inc_id).attr("disabled", "disabled");

   });
