基于其他多选下拉列表的多选下拉列表 [英] multiselect dropdown based on other multiselect dropdown

问题描述

我正在尝试根据另一个多选下拉列表中的选择来显示/隐藏多选下拉列表中的元素.无论如何，当我使用 multiselect插件时我无法显示/隐藏元素.我的代码如下:

I am tryng to show/hide elements in a multiselect dropdown, based on the selection in another multiselect dropdown. Anyway, when I use the multiselect plugin I am not able to show/hide the elements. My code looks like this:

@Html.DropDownList("CompanyDropDown", new MultiSelectList(ViewBag.CompanyList,
         "COD_COMPANY", "DESCRIPTION", null), new
                {
                    multiple = "multiple",
                    @class = "multiselect",
                    onchange = "CompanyDropDownOnChange()"
                })


@Html.DropDownList("FlowDropDown", new MultiSelectList(ViewBag.ActiveFlow,
         "ID_FLOW", "DESCRIPTION", null), new
                {
                    multiple = "multiple",
                    @class = "multiselect",
                })

而javascript部分在这里:

and the javascript part is here:

jQuery(function ($) {
    $("select").multiselect();
});   
function CompanyDropDownOnChange() {
    $("#FlowDropDown option[value=11]").css('display', 'none');
}

样品应该只是隐藏在第二个下拉，当在第一下拉一个公司选择具有ID = 11的流动.

The sample should just hide the flow with id=11 in the second dropdown, when a company in the first dropdown is selected.

推荐答案

我对像您这样的场景进行了一些测试，发现您正在更改错误的元素.

I did some testing with a scenario like yours and found out that you were altering the wrong elements.

function CompanyDropDownOnChange() {
 $("input[name=multiselect_FlowDropDown][value=11]").closest('li').css('display', 'none');
}
