我在内容编辑器 Web 部件中添加了一些 JavaScript 代码，以影响出现在列表中的日期颜色。该列表使用预览窗格设计设置，并且需要应用 javascript 代码的多个条目。

javascript 选择日期并根据日期与今天日期的关系决定日期是否需要为绿色、黄色或红色。加载时，javascript 在预览窗格中显示的第一个条目上正常工作，但在选择其他条目时颜色不会根据需要更改。我需要在我的 JavaScript 中添加/更改什么才能将 JavaScript 条件单独应用于列表中的每个条目？

以下是列表在页面上的样子：

这是放置在内容编辑器 Web 部件中的 JavaScript：

<script src="/agencies/wtc/cop/wtctasks/SiteAssets/jquery-1.8.1.min.js"></script><script>

$(document).ready(
function ()
{
       $("div.ms-ppleft table tr td.ms-vb-title").trigger("onfocus");
}
)

_spBodyOnLoadFunctionNames.push("FormatDates");

function FormatDates()
{
var contentTable = document.getElementById("MSO_ContentTable");
var tables = contentTable.getElementsByTagName("TABLE");
var formTable;

// find the table we need to work with

for (i = 0; i < tables.length; i++)
{
    if (tables[i].summary.trim() == "Training Records")
    {
        var innerTables = tables[i].getElementsByTagName("TABLE");

        for (j = 0; j < innerTables.length; j++)
        {
            if (innerTables[j].className == "ms-formtable")
            {
                formTable = innerTables[j];

        }
    }

非常感谢你的帮助。

一种方法可能是将您的FormatDates方法设置为在用户将鼠标悬停在项目标题上时触发。

var titles = document.querySelectorAll(".ms-vb-title");
for(var i = 0, len = titles.length; i < len; i++){
    var method = titles[i].attachEvent ? "attachEvent" : "addEventListener";
    titles[i][method]((titles[i].attachEvent ? "on" : "")+"mouseenter",FormatDates);
}

FormatDates上面的代码将该方法附加到mouseenter每个项目标题的事件上（假设标题是用 CSS 类装饰的ms-vb-title）。
