我有一个下拉菜单需要触发带有已单击 id 值的 Url.Action
目前我有:模型
using System.Collections.Generic;
using System.Data.Entity;
using System.Web.Mvc;
namespace Portal.Models
{
public class CompanyViewModel
{
public int Id { get; set; }
public string CompanyName { get; set; }
public IEnumerable<SelectListItem> CompaniesList { get; set; }
}
public class CompanyViewModelDbContext : DbContext
{
public DbSet<CompanyViewModel> Contacts { get; set; }
}
}
看法
@model Portal.Models.CompanyViewModel
@{
ViewBag.Title = "ShowDropdown";
}
@Html.DropDownListFor(m => m.Id, new SelectList(ViewBag.CompanyList as System.Collections.IEnumerable, "CoId","CompanyName"), Url.Action("SelectCompany", "Home", new { partnerCoId = "CoId" }, null))
控制器方法
public PartialViewResult ShowDropdown()
{
var coid = Lt.GetThisUsersCoId();
var model = new CompanyViewModel();
using (var dc = new CompanyViewModelDbContext())
{
var content =
(from cr in db.CompanyRelationship
//This is grabbing all related companies to the logged in user
join c in db.Companies on cr.CoId equals c.CoId
where cr.PartnerCoId == coid
select new
{
cr.CoId,
c.CompanyName
}).Distinct().ToList();
ViewBag.CompanyList = content;
foreach (var item in content)
{
model.Id = item.CoId;
model.CompanyName = item.CompanyName;
}
}
return PartialView(model);
}
public ActionResult SelectCompany(int partnerCoId, string redirect)
{//Bunch of code that I didn't write but just needs to be triggered on click
下拉列表应根据全球价值列出一堆公司,选择一个后,它会建立关系。
我要完成的工作:根据从下拉列表中选择的内容触发 ActionResult SelectCompany。目前它似乎没有做任何事情,我应该在 VS 中使用任何好的调试工具来查看单击下拉菜单时会发生什么。从我的前端看来,当我选择一家公司时,好像什么都没有发生。
更新 我已经在我的视图中调用了脚本,但是我在使用其中的@url.Action 时遇到了问题,我必须通过这个:
@Url.Action("SelectCompany", "Home", new {partnerCoId = x})
从下拉列表中选择的值。
