javascript - 将单个模型值(字符串)作为参数传递给可重用的 javascript 函数，以在 MVC View 中设置表格单元格类

Question

我的 View 显示一个表格，其中包含一些数据的状态，按列分组:

• 准备就绪
• 完成
• 已跳过
• 不适用

我每次都有大约 6 列和多行(下面是简化的示例) 我需要设置单元格背景颜色，这可以通过 css 轻松完成，但是每次通过 View 中的重复代码设置样式类对于每列来说都是非常耗时的，而且容易出错。

所以我想到使用一个javascript函数，使用模型值(上面列出的状态)的参数来动态设置类css样式。

我不是 100% 确定如何去做。

示例代码:

@using NS.Data
@model NS.Models.PublicationsModel


@{
    ViewBag.Title = "PublicationState";
    Layout = "~/Views/Shared/_Layout.cshtml";
    var PublicationState = Model.PublicationState.ToList();
}
@*Below the idea of the intended "reusable" javascript function*@
<script type="text/javascript" language="javascript">
    $(function ToggleCellColour(StepState) {

        switch (StepState) {
            case "Ready":
                return "cssReadyState";
                break;
            case "Done":
                return "cssDoneState";
                break;
            case "Skipped":
                return "cssSkippedState";
                break;
            default:
                return "";
                break;
        }
    });
</script>
<h2>Publication State</h2>

@Html.ActionLink("Back to previous page", "ActionName", "ControllerName", new { returnActive = true }, null)
<table class="table">
    <tr>
        <th>Client</th>
        <th>Availability Communicated to Team</th>
        <th>Schedule Test</th>
        <th>Tested</th>
        <th>Planned Prod Implementation</th>
        <th>Implemented to Prod</th>
    </tr>
    @*Returned Publication States: N/A, Ready, Skipped, Done*@
    @foreach (var PubSt in PublicationState)
    {
           <tr>
                <td>@PubSt.Client</td>
                <td align="center" class="ToggleCellColour(@PubSt.Availability_Communicated_to_Team)"> @*This is where I thought of calling the javascript method to determine the css formatting for the cell*@
                    @if (PubSt.Availability_Communicated_to_Team != "N/A")
                    {
                        if (PubSt.Availability_Communicated_to_Team == "Done" || PubSt.Availability_Communicated_to_Team == "Skipped")
                        {
                            <img src="~/Images/MailClosed.png" />
                        }
                        else @*The "Ready" State*@
                        {
                            <img src="~/Images/MailOpen.png" />
                        }
                    }
                    else
                    {
                        @PubSt.Availability_Communicated_to_Team
                    }
                </td>
                <td align="center" class="ToggleCellColour(@PubSt.Schedule_Test)">
                    @if (PubSt.Schedule_Test != "N/A")
                    {
                        if (PubSt.Schedule_Test == "Done" || PubSt.Schedule_Test == "Skipped")
                        {

                        if (PubSt.Tested == "Done" || PubSt.Tested == "Skipped")
                        {
                            <img src="~/Images/MailClosed.png" />
                        }
                        else
                        {
                            <img src="~/Images/MailOpen.png" />
                        }
                    }
                    else
                    {
                        @PubSt.Tested

                        if (PubSt.Planned_Prod_Implementation == "Done" || PubSt.Planned_Prod_Implementation == "Skipped")

                    }
                    else
                    {
                        @PubSt.Planned_Prod_Implementation

                        {
                            <img src="~/Images/MailClosed.png" />
                        }
                        else
                        {
                            <img src="~/Images/MailOpen.png" />
                        }
                    }
                    else
                    {
                        @PubSt.Implemented_on_Prod
                    }
                </td>
            </tr>
        }
    }
</table>

可以重复 if else 语句代码，就像我显示图像时所做的那样，但是我认为通过使用 javascript 函数来简化事情，可以省去麻烦并引入更少的错误。

任何帮助将不胜感激。

如果您使用 JQuery，您可以向单元格添加数据属性以及一些允许您定位它的标识符(例如类名)，然后让不显眼的 JS 为您设置 CSS 类:

<tr>
    <td class="coloredCell" data-availability="@PubSt.Planned_Prod_Implementation">stuff</td>
</tr>

然后使用JS设置文档颜色:

$(function ()
{
    $('.coloredCell').each(function (index, element)
    {
        var availability = $(element).attr("data-availability");
        var cssClass;
        switch (availability)
        {
            case "Ready":
                cssClass = "cssReadyState";
                break;
            case "Done":
                cssClass = "cssDoneState";
                break;
            case "Skipped":
                cssClass = "cssSkippedState";
                break;
            default:
                cssClass = "";
                break;
        }
        $(element).addClass(cssClass);
    });
});
