如何选择除第一个div之外的所有body元素

I have this HTML:

我有这个HTML:

<body>
    <div id="switcher" class="switcher">
        <h3>Style Switcher</h3>
        <button id="switcher-default">
                Default
        </button>
        <button id="switcher-narrow">
            Narrow Column
        </button>
        <button id="switcher-large">
            Large Print
        </button>
    </div>
    <p>asdfasdfasdfas dsadf</p>
    <p>asd'lfkasdf</p>

    <script src="jquery.js"></script>
    <script src="test.js"></script>
</body>

I want to add a class to all body elements except my first div (which has the id called switcher), when I click on the Large print button.

当我点击Large print按钮时,我想在除了我的第一个div(其id为cuther)之外的所有body元素中添加一个类。

I have tried

我试过了

 $(document).ready(function(){
   $("#switcher-large").bind("click", function(){       
    $("body:not(:first-child)").addClass("large");      
    });
});

and

$(document).ready(function(){
   $("#switcher-large").bind("click", function(){       
    $("body:not(div)").addClass("large");       
    });
});

and

$(document).ready(function(){
       $("#switcher-large").bind("click", function(){       
        $("body").not("#switcher").addClass("large");       
        });
    });

but none seem to work (the class applies to all elements).

但似乎没有工作(该类适用于所有元素)。

I don't want to find an alternate way like selecting only p elements. I just want to understand why the selectors I used don't work...

我不想找到另一种方法,比如只选择p元素。我只是想明白为什么我使用的选择器不起作用......

2 个解决方案

#1

You need to exclude the document.body itself. Like

您需要排除document.body本身。喜欢

$("body *").not("#switcher").addClass("large");

This will query for all children of body, excluding #switcher. Maybe more convinient:

这将查询身体的所有孩子,不包括#switcher。也许更方便:

$(document.body).contents().not('#switcher').addClass('large');

#2

$("body").children().not("#switcher").addClass("large");
