javascript - 如何使用 Javascript 根据内容更改表格行颜色

Question

我想用来自 php 请求的内容填充表格。根据内容我有 4 个状态我想用来定义引导 TR 类。

下面是我的代码片段。我已经将类(class)分配给 TR，但这可能需要更改。

规则应该已经显示在下面代码段的 TR 类中。

条件如下:

预期 = bg-成功

已取消 = bg-danger

Inhouse = bg-info

部分 = bg-警告

已完成 = bg-active

因为我想使用 php foreach 或 while 来填充表格，我如何使用 javascript 或 jquery 使表格动态更改行的颜色？

function reservationListFunction() {
  // Declare variables
  var input, filter, table, tr, td, i;
  input = document.getElementById("reservationListInput");
  filter = input.value.toUpperCase();
  table = document.getElementById("reservationTable");
  tr = table.getElementsByTagName("tr");

  // Loop through all table rows, and hide those who don't match the search query
  for (i = 0; i < tr.length; i++) {
    td = tr[i].getElementsByTagName("td")[0];
    if (td) {
      if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
        tr[i].style.display = "";
      } else {
        tr[i].style.display = "none";
      }
    }
  }
}

jQuery(document).ready(function($) {
    $('#reservationTable tr').each(function () {
       var td_value = $('td',this).eq(3).text();
       switch (td_value) {
           case 'Partial':
                $(this).addClass('bg-warning');
               break;
               ....
               And So On
               ....
           default:
               // statements_def
               break;
       }
    });
});

#reservationListInput {
  background-image: url('./assets/fonts/searchicon.png');
  /* Add a search icon to input */
  background-position: 10px 12px;

  border: 1px solid #ddd;
  /* Add a grey border */
  margin-bottom: 12px;
  /* Add some space below the input */
}

  border-collapse: collapse;
  /* Collapse borders */
  width: 100%;
  /* Full-width */
  border: 1px solid #ddd;
  /* Add a grey border */

  /* Increase font-size */
}

#reservationTable th,
#reservationTable td {
  text-align: left;
  /* Left-align text */
  padding: 12px;
  /* Add padding */
}

  /* Add a bottom border to all table rows */
  border-bottom: 1px solid #ddd;
}

#reservationTable tr.header,

  /* Add a grey background color to the table header and on hover */

希望这能给你一些见识......

jQuery(document).ready(function($) {
    $('#reservationTable tr').each(function () {
       var td_value = $('td',this).eq(3).text();
       switch (td_value) {
           case 'Partial':
                $(this).addClass('bg-warning');
               break;
               ....
               And So On
               ....
           default:
               // statements_def
               break;
       }
    });
});
