使用 JQuery 动态禁用多选选项答案

【问题标题】：Disable multiselect option dynamically using JQuery使用 JQuery 动态禁用多选选项
【发布时间】：2017-03-18 05:07:17
【问题描述】：

我有两个多选下拉菜单，其中都有相同的一组值。

如果您在第一个下拉菜单中选择一个选项，则在第二个下拉菜单中应该禁用该选项。

我可以为第一个选项做，但不能为后续选项做。

请帮忙

用你试过的代码提供一个jsfiddle
当我尝试它时它会起作用..jsfiddle.net/456puc9k

标签： javascript jquery multi-select

【解决方案1】：

这可以通过相对选择器来完成。我为此使用了option 点击事件。然后我抓住另一个表单组并对其进行修改。它适用于两种方式，这意味着如果您从选择 A 中选择，则选择 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
});

前面的答案对多选无效，我已经修改了代码以匹配多选

$(".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);
    });
});

这很有帮助。大力支持。非常感谢！

【解决方案3】：

在选择中，CURRENCY 和 WINTER 中的 Id 值都相同，我已更改它，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");

   });
