javascript - 如何使用 Mootools 使单选按钮选项依赖于其他单选按钮选项？

Question

我有一个表格，其中有 6 个项目，每个项目都可以按重要性顺序从 1 到 6 排列。

Here's a screenshot.

基本上，我需要对其进行设置，以便如果一项的排名为 3(例如)，则“3”对于所有其他项都将被禁用。

因此，用户应该只能为每个项目选择尚未选择的数字(这样我们可以确保项目确实会排名1-6，并且不同项目不会重复数字) .

这是我正在使用的标记(减去演示 div):

    <input id="importantProductQuality_0" name="importantProductQuality" value="1" type="radio">
    <label for="importantProductQuality_0">1</label>

有什么想法吗？

Answer 1

根据您提供的标记，这是 mootools 的方法。

// Get the list of items for the second set.
var importantPrices = $$('input[name=importantPrice]');

// Add an event to each radio input in the first set
$$('input[name=importantProductQuality]').addEvent('click', function(e) {

  var target = $(e.target);

  // If one of the buttons in the first set is selected, disable the
  // one with the matching value in the second set.
  if (target.get('checked')) {
    importantPrices.each(function(radio) {
      radio.set(disabled, radio.get('value') == target.get('value');
    });
  } else {
    // Enable all again
    importantPrices.set('disabled', false);
  } 
});
