Question

我在Visual Studio 2013中正在做这个项目，它是一个MVC应用程序。所以我在这里有这个webgrid：

@gridSensorChoose.GetHtml(
    mode: WebGridPagerModes.All,
    columns:

    gridSensorChoose.Columns(

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

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

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

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

    gridSensorChoose.Column("VAL", format: @<text><input type="checkbox" name="val" id="Val"/></text>),

    gridSensorChoose.Column("MIN", format: @<text> <input type="checkbox" name="min" id="Min"/> </text>),

    gridSensorChoose.Column("AVG", format: @<text> <input type="checkbox" name="avg" id="Avg" /> </text>),

    gridSensorChoose.Column("MAX", format: @<text> <input type="checkbox" name="max" id="Max" /> </text>),

    gridSensorChoose.Column("SUM", format: @<text> <input type="checkbox" name="sum" id="Sum" /> </text>),

    gridSensorChoose.Column("INT", format: @<text> <input type="checkbox" name="int" id="Int" /> </text>)

                                ))

现在我想隐藏 ONLY 最后两行的复选框（在我的情况下＆＃34; SUM＆＃34;和＆＃34; INT＆＃34;），但也离开如果第三行的值（在我的情况下是@ item.SensorType）小于100，则显示的行和culmns（无论它们是否显示）。

我在java脚本中开始做的是：

<script type="text/javascript">
$(function () {
    var tr = $(this).parents('tr:first');
    var SensorType = tr.find("#SensorType").html();
    if (SensorType < 100) {
        $("#Sum").hide();
        $("#Int").hide();
    }
});
</script>

然后我意识到必须完成另一个动作才能让tr工作，因为没有选择任何东西，我只想在页面加载时工作 - 只要显示webgrid。 Cna有人帮忙吗？

这是输出：

<table class="webgrid2-table">
<thead>
    <tr class="webgrid2-header">
        <th scope="col">
            <a href="/PredefinedViews/CreateSensorList?selDeviceID=1&amp;sort=SensorID&amp;sortdir=ASC">SensorID</a>

在您发表评论并发布您的实际html结构后，解决方案完全不同。首先 ID 应该是唯一的。您可以改用类。其次，您可以使用jquery .each()来迭代表格，如下所示：

$("table tr").not(":first").each(function() {
  //chech if sensorType is less than 100 and hide the checkboxes
  if (~~$(this).find(".SensorType").text() < 100) {
    $(this).find(".sum").hide();
    $(this).find(".int").hide();
  }
});

table tr td {
  border: solid 1px;
}

你可以发一个小提琴吗？也许这可以做到：

$('tr').not(':first').each(function() {
    var $tr = $(this),
        sensorTypeVal = parseInt($tr.find('td').eq(2).find('span').text());
    if(sensorTypeVal < 100) {
        $tr.find('td').eq(-1).find('input').hide();
        $tr.find('td').eq(-2).find('input').hide();
    }
});
