javascript - 如何从 MVC 项目中的每个表行获取每个值？

Question

我认为有以下网络网格:

@using (Html.BeginForm("InsertSensorsInExistingPredefineView", "PredefinedViews", FormMethod.Post))
{

@gridSensorChoose.GetHtml(
    tableStyle: "webgrid3-table",
    headerStyle: "webgrid3-header",
    footerStyle: "webgrid3-footer",
    alternatingRowStyle: "webgrid3-alternating-row",//
    selectedRowStyle: "webgrid3-selected-row",
    rowStyle: "webgrid3-row-style",//
    mode: WebGridPagerModes.All,
    columns:

    gridSensorChoose.Columns(

    gridSensorChoose.Column("SensorID", format: @<text>  <input readonly="readonly" name="SensorID" id="SensorID" value="@item.SensorID" />  </text>, style: "col1Width"),

    gridSensorChoose.Column("DeviceID", format: @<text>  <span id="DeviceID">@item.DeviceID</span>  </text>, style: "col1Width"),

    gridSensorChoose.Column("SensorType", format: @<text>  <span id="SensorType" class="SensorType">@item.SensorType</span>  </text>, style: "col1Width"),

    gridSensorChoose.Column("SensorName", @Html.Localize("sensorName").ToString(), format: @<text>  <span><label id="SensorName">@item.SensorName</label> </span>  </text>, style: "col2Width", canSort: false),

    gridSensorChoose.Column("VAL", format: @<text><span class="Val"> @Html.CheckBox("val") </span></text>, style:"col1Width", canSort: false),

    gridSensorChoose.Column("MIN", format: @<text><span class="Min"> @Html.CheckBox("min") </span> </text>, style: "col1Width", canSort: false),

    gridSensorChoose.Column("AVG", format: @<text> <span class="Avg"> @Html.CheckBox("avg") </span> </text>, style: "col1Width", canSort: false),

    gridSensorChoose.Column("MAX", format: @<text> <span class="Max"> @Html.CheckBox("max") </span> </text>, style: "col1Width", canSort: false),

    gridSensorChoose.Column("SUM", format: @<text> <span class="Sum"> @Html.CheckBox("sum") </span> </text>, style: "col1Width", canSort: false),

    gridSensorChoose.Column("INT", format: @<text> <span class="Int"> @Html.CheckBox("int") </span> </text>, style: "col1Width", canSort: false)

                                ))


<input type="submit" value="@Html.Localize("save")" formaction="/PredefinedViews/InsertSensorsInExistingPredefineView" />
}

此 View 在浏览器中显示以下 html，如下所示:

<table class="webgrid3-table">
<thead>
    <tr class="webgrid3-header">
        <th scope="col" style="display: none;">
            <a href="/PredefinedViews/CreateSensorList?   selDeviceID=1&amp;sort=SensorID&amp;sortdir=ASC">SensorID</a>
        </th>
        <th scope="col" style="display: none;">
            <a href="/PredefinedViews/CreateSensorList?selDeviceID=1&amp;sort=DeviceID&amp;sortdir=ASC">DeviceID</a>
        </th>
        <th scope="col" style="display: none;">
            <a href="/PredefinedViews/CreateSensorList?selDeviceID=1&amp;sort=SensorType&amp;sortdir=ASC">SensorType</a>

所以我现在想要获取每行的每个复选框(总共有六个复选框)的每个值(即使它是假的)(可以是从零到任何数字，具体取决于有多少个 SensorID) (这是唯一的)DeviceID(每行都相同))。但我不知道如何迭代每一行。我尝试使用 FormCollection，但这对我来说不起作用，有人有任何其他建议可以帮助我吗？

public ActionResult InsertSensorsInExistingPredefineView(FormCollection sensorCollection)
    {

        foreach (var row in sensorCollection.AllKeys)

            bool _val = sensorCollection["val"] != "false";
            bool _min = sensorCollection["min"] != "false";
            bool _avg = sensorCollection["avg"] != "false";
            bool _max = sensorCollection["max"] != "false";
            bool _sum = sensorCollection["sum"] != "false";
            bool _int = sensorCollection["int"] != "false";

            if (//some logic checking for at least one true value)
            {
               //save to some db table acording to sensorID....
            }

        }
        return view;
    }

我做了整个 != "false"事情，因为复选框以字符串形式返回值，就像如果选中则以“true,false”形式出现的字符串，如果未选中则以“false”形式返回的字符串。 我在这里一定做错了什么，我刚刚编辑了我的第一行(SensorID)，认为它可以作为计数器，但我仍然在挣扎。

我不知道在这里要做什么，我是否有机会使用 Javascript/jQuery 完成我的任务，然后将结果发送到 Controller ？

我只是尝试看看它是否会迭代每一行并获取值:

    <input type="submit" class="DoSomething" value="Do it" />
foreach (WebGridRow row in gridSensorChoose.Rows)
{
    <script type="text/javascript">
        $(function () {
            $(".DoSomething").on("click", function () {
            var tr = $(this).parents('tr:first');
            var sensorID = tr.find(".SensorID").html();
            var _val = tr.find(".Val").html();
            var _min = tr.find(".Min").html();
            var _avg = tr.find(".Avg").html();
            var _max = tr.find(".Max").html();
            var _sum = tr.find(".Sum").html();
            var _int = tr.find(".Int").html();
            })
            if (_val == true || _min =! true || _avg == true || _max == true || _sum == true || _int == true ||){
                //ajax send all vars to controller
                }
            //and now iterate through next row

        })
    </script>

也许我可以在java脚本中写出类似的东西，并在每次结束迭代时将其发送到 Controller ？然后它开始一个新的行，直到没有更多的行。

根据您的代码行，我发现您误解了某些内容

foreach (var row in sensorCollection.AllKeys) 
{

}

sensorCollection 中的值不是行。它们是从 View 传递的字段。

您的 HTML 有很多同名的输入。举个例子:

<input id="val" name="val" type="checkbox" value="true">

sensorCollection.AllKeys 将包含“val”的多个条目 - 网格上的每一行都有一个条目。您将迭代每个值，然后忽略该值并再次检索该值。本质上是这样的

foreach (var row in sensorCollection.AllKeys)
{
    bool _val = sensorCollection["val"] != "false";
    bool _min = sensorCollection["min"] != "false";
    bool _avg = sensorCollection["avg"] != "false";
    bool _max = sensorCollection["max"] != "false";
    bool _sum = sensorCollection["sum"] != "false";
    bool _int = sensorCollection["int"] != "false";
}

相当于:

for(int i = 0; i < number_of_rows; i++)
{
    bool _val = sensorCollection["val"] != "false";
    bool _min = sensorCollection["min"] != "false";
    bool _avg = sensorCollection["avg"] != "false";
    bool _max = sensorCollection["max"] != "false";
    bool _sum = sensorCollection["sum"] != "false";
    bool _int = sensorCollection["int"] != "false";
}

看看i 在那里是如何不相关的？ row 也是如此。您没有引用它，因此这些值将始终相同 - 可能是网格上第一行的值。

你需要做这样的事情

// find the number of values for "val" in the collection
// build a for loop that iterates over the collection
for(int i = 0; i < sensorCollection.AllKeys.Where(k => k == "val").Count(); i++)
{
    // get the nth of each key, where n is the instance of "val"  
    bool _val = sensorCollection.AllKeys.Where(k => k == "val")[i] != "false";
    // handle the other values (I'm too lazy to type them out)
    // save out the data
}

更新

好的，我构建了一个新的 MVC 应用程序并复制了您的网格和回发，这就是我发现的内容。

首先，sensorCollection.AllKeys中有6个值 - 每列一个值(val,min,avg,max,sum,int)

其次，由于某种原因，数据被编码为串联字符串。因此，如果您勾选第一个 val 复选框，则 sensorCollection[0] = "true,false,false,false,false,false,false,false,false,false,false,false,false"

我没想到会这样，这有点奇怪，但我们会解决它。这段代码应该可以解决你的问题:

public ActionResult InsertSensorsInExistingPredefineView(FormCollection sensorCollection)
{
    bool[] vals = sensorCollection["val"].Split(',').Select(x => Convert.ToBoolean(x)).ToArray();
    bool[] mins = sensorCollection["min"].Split(',').Select(x => Convert.ToBoolean(x)).ToArray();
    bool[] avgs = sensorCollection["avg"].Split(',').Select(x => Convert.ToBoolean(x)).ToArray();
    bool[] maxs = sensorCollection["max"].Split(',').Select(x => Convert.ToBoolean(x)).ToArray();
    bool[] sums = sensorCollection["sum"].Split(',').Select(x => Convert.ToBoolean(x)).ToArray();
    bool[] ints = sensorCollection["int"].Split(',').Select(x => Convert.ToBoolean(x)).ToArray();

    for (int i = 0; i < vals.Count(); i++)
    {
        // your first row, "Soil Temperature":
        bool val = vals[i];
        bool min = mins[i];
        // etc
    }

}
