Question

我试图拉出两个变量，一个来自TextBox（“搜索”），另一个来自RadioButton（“searchBy”），并在单击ActionLink时将它们拉入控制器。

当我使用带有提交按钮的搜索表单时，“搜索”和“搜索”字符串被拉入控制器。但如果我单击其中一个ActionLinks，我只会得到“sortOrder”字符串。我认为这是因为ActionLink没有提交？

所以我认为有两种方法可以解决它，因此我的两个问题是：

是否可以让ActionLink在单击的表单上执行提交？
是否可以使用ActionLink拉出“search”和“searchBy”字符串？

我的家庭控制器：

 public ActionResult Index(string searchBy, string search, string sortOrder)
    {
        ViewBag.NameSortParm = String.IsNullOrEmpty(sortOrder) ? "name_desc" : "";
        ViewBag.TextSortParm = String.IsNullOrEmpty(sortOrder) ? "text_desc" : "";
        ViewBag.PriceSortParm = sortOrder == "Price" ? "price_desc" : "Price";
        ViewBag.CubicMeterSortParm = sortOrder == "CubicMeter" ? "cubicMeter_desc" : "CubicMeter";
        ViewBag.PricePerCubicSortParm = sortOrder == "PricePerCubic" ? "pricePerCubic_desc" : "PricePerCubic";
        ViewBag.ConstructionTypeSortParm = sortOrder == "constructionType" ? "constructionType_desc" : "constructionType";

        var text = from s in db.LearningNumbers select s;

        if (!String.IsNullOrEmpty(search))
        {
            if (searchBy == "Tekst")
            {
                text = text.Where(x => x.Note.Contains(search) || search == null);
            }
            else
            {
                text = text.Where(x => x.Name.Contains(search) || search == null);
            }
        }

        switch (sortOrder)
        {
            case "name_desc":
                if (searchBy == "Tekst")
                {
                    text = text.OrderByDescending(s => s.Name).Where(x => x.Note.Contains(search) || search == null);
                }
                else
                {
                    text = text.OrderByDescending(s => s.Name).Where(x => x.Name.Contains(search) || search == null);
                }
                break;
            case "text_desc":
                if (searchBy == "Tekst")
                {
                    text = text.OrderByDescending(s => s.Note).Where(x => x.Note.Contains(search) || search == null);
                }
                else
                {
                    text = text.OrderByDescending(s => s.Note).Where(x => x.Name.Contains(search) || search == null);
                }
        }
        return View(text.ToList());
    }

我的索引视图：

 @using (Html.BeginForm("Index", "Home", FormMethod.Get, new { id = "searchForm" }))
    {
<div class="row">
<div class="col-md-12">
    <hr />
    <h2>Søgeresultater</h2>
        @Html.RadioButton("searchBy", "Navn", true) <text>Navn</text>
        @Html.RadioButton("searchBy", "Tekst") <text>Tekst</text><br />
        @Html.TextBox("search")<input class="btn btn-primary" style="margin:0 10px;" type="submit" value="Søg" />

</div>

<div class="col-md-12 table" style="display:table; margin:45px 0 25px 0;">
    <div class="col-md-2">
        @*<b>Tekst</b><br />*@
        <h4>@Html.ActionLink("Navn", "Index", new { sortOrder = ViewBag.NameSortParm, onclick = "document.getElementById('searchForm').submit();" } })</h4>
    </div>
    <div class="col-md-2">
        @*<b>Tekst</b><br />*@
        <h4>
            @Html.ActionLink("Tekst", "Index", new { sortOrder = ViewBag.TextSortParm, onclick = "document.getElementById('searchForm').submit();" } })
        </h4>
    </div>
</div>
</div>
}

1。您可以在操作链接中使用JavaScript来执行提交：

@Html.ActionLink("Tekst", "Index", new { 
     sortOrder = ViewBag.TextSortParm,  
     onclick = "document.getElementById('<your form id>').submit();"
})

不要忘记在表单中添加Id（）。

使用ActionLink的MVC，Pull TextBox和RadioButton变量
