当我点击id #platinum复选框时，我想从id #schedule复选框中删除禁用...
答案 0 :(得分：0)
不允许在文档中使用多个具有相同id的DOM元素。您应该确保id在您的网页上是唯一的。
考虑到这一点，您可以按name[]选择元素并以这种方式禁用它们：
jQuery＆lt; 1.6,1.61
$(document).ready(function() {
$("#platinum").click(function() {
$("input[name='schedule[]']").removeAttr("disabled");
});
});
jQuery＆gt; = 1.6
$(document).ready(function() {
$("#platinum").click(function() {
$("input[name='schedule[]']").prop("disabled", false);
});
});
