jquery - jquery on click checkbox issue

Question

Here is the Fiddle.

So I've set up this little example of what I am trying to do. I want this checkbox to work as the following. When user tries to enable/click the checkbox (mostly for people who are not computer savvy), I would like for it to alert them saying "You must login to do this action".

I can't figure it out. I've been searching all over for an answer, and couldn't find one.

Thanks a lot in advance for all your answers!

Answer 1

只需disabled从复选框中删除属性。此外，如果您只想在选中复选框时显示警报，请改用以下内容：

$(".check").click(function() {
    if (this.checked) {
        alert("You must sign in to do this.");
    }
});

Answer 2

删除选中和禁用属性并使用以下代码：

$(".check").click(function() {
    if ($(this).is(':checked')) alert("You must sign in to do this.");
});​
