jquery - 根据多个选择/隐藏元素更改表格行颜色

Question

我有一张 table 。在每一行我都有一个复选框来“选择它”，两个选择框和一个额外的复选框。

当我显示我的页面时，每一行的背景颜色都是默认的(白色)。

我需要的是两件事:

1. 对于每个“操作”选择框值，我希望行更改其颜色，但前提是行复选框被选中 - 绿色表示“创建”，红色表示“删除”

2. 如果“操作”选择框的值等于“删除”，我希望禁用第二个选择框和额外的复选框。

目前，我有以下代码仅根据第一个选择框选择更改行背景颜色，而不考虑复选框的状态。

我该如何实现？我不知道如何让这些条件协同工作。

谢谢。

注意:我在 Drupal 中使用此代码，但它是通用的。第二个注意:这是在 drupal 中使用的，所以我使用的主题已经有表格的 css。例如，当我将鼠标悬停在奇数/偶数行时，已经应用了一些颜色。不知道这是否会影响实现我需要的代码。

您必须将更改事件绑定(bind)到 select 和 checkbox。然后

1. 使用 $(this).closest('tr') 获取更改事件中的父级 tr。
2. 首先使用$tr.find('.containers_table').is(':checked')查找复选框状态并在更改颜色时考虑它。
3. 使用 $tr.find('.update-card_configuration, .update-ne_configuration') 查找额外的select & checkbox。并根据操作值使用 prop() 方法启用/禁用它们。

var Drupal = function() {};
Drupal.behaviors = function() {};

(function($) {
  Drupal.behaviors.mymoduleColorRows = {
    attach: function(context) {

      // Bind change event to select
      $('.update-action, .containers_table').change(function() {
        // Get color from value of select & checkbox
        var $tr = $(this).closest('tr'),
          color = '#F5BE8B',
          value = $tr.find('.update-action').val(),
          status = $tr.find('.containers_table').is(':checked');

        if (value == 'create' && status)
          color = '#D7EAD9';

        //enable/disable extra select box and checkbox
        $tr.find('.update-card_configuration, .update-ne_configuration').prop('disabled', value == 'delete');

        // Set color
        $tr.css('background-color', color);
      });

      //call event on first page load
      $('.update-action').change();
    }
  };
})(jQuery);

Drupal.behaviors.mymoduleColorRows.attach();
