为什么我的javascript/jquery代码不能像预期的那样工作?
I have a code where I expect my checkboxes to be selected and disabled. When I click Zero, all checkboxes should be highlighted, all checkboxes except zeroth checkbox should be disabled. Similarly for one, two and three radio buttons. This does not seem to happen consistently. I am trying it on chrome browser version 48.0.2564.116. Also, the behavior is horrible on Firefox. Can someone please let me know what I am doing wrong?
我有一个代码，我希望我的复选框被选中和禁用。当我单击0时，所有复选框都应该突出显示，除零之外的所有复选框都应该被禁用。1、2、3个单选按钮也是如此。这似乎不是始终如一的。我正在chrome浏览器48.0.2564.116版本上试用。另外，Firefox的行为非常糟糕。有人能告诉我我做错了什么吗?

I think this should do the trick (if I get your question correctly)
我想这应该能起到作用(如果我答对了你的问题)
$("input[type=radio]").click(function(e) {
var whats_selected = $(this).val();
// check an disable all checboxes
$("input[type=checkbox]")
.attr('checked', true)
.prop('disabled', true);
// enable the targetted checkbox
$('#chkbox' + whats_selected)
.prop('disabled', false);
});
