Question

对于popover一个部门，我正在使用此代码。我想添加多个元素。当我添加具有相同id的多个元素时，脚本不起作用。怎么解决？脚本是。

<a href="#" id="button">Click me</a>
<div id="modal">
    <div id="heading">
        Are you sure you want to do that?
    </div>  
</div>
<!--jQuery-->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="js/jquery.reveal.js"></script>

<script type="text/javascript">
        $(document).ready(function() {
                $('#button').click(function(e) { // Button which will activate our modal
                        $('#modal').reveal({ // The item which will be opened with reveal
                                animation: 'fade',                   // fade, fadeAndPop, none
                                animationspeed: 600,                       // how fast animtions are
                                closeonbackgroundclick: true,              // if you click background will modal close?
                                dismissmodalclass: 'close'    // the class of a button or element that will close an open modal
                        });
                return false;
                });
        });
</script>

我想这样添加。

<a href="#" id="button">Click me</a>
    <div id="modal">
        <div id="heading">
            Are you sure you want to do that?
        </div>  
    </div>
<a href="#" id="button">Click </a>
    <div id="modal">
        <div id="heading">
            You want to do that?
        </div>  
    </div>

Answer 1

ID是唯一。规范只允许每个id一个元素。

改为使用班级

<div class="toActOn">
        Are you sure you want to do that?
</div>  
<div class="toActOn">
        Really sure
</div>

然后在jQuery中将您的选择器更改为.toActOn（即$(".toActOn")）

这解释了根据the W3c

的ID

使ID类型属性特殊的原因是，无论承载它们的元素的类型如何，在符合的文档中没有两个这样的属性可以具有相同的值;无论文档语言如何，ID类型属性都可用于唯一标识其元素。在HTML中，所有ID属性都被命名为“id”;

Answer 2

使用class而不是id来标识元素......

<a href="#" class="button" modal="m1">Click me</a>
<div id="m1">
    <div id="heading">
        Are you sure you want to do that?
    </div>  
</div>
<a href="#" class="button" modal="m2">Click</a>
<div id="m2">
    <div id="heading">
        Are you sure?
    </div>  
</div>
<a href="#" class="button" modal="m3">Click this</a>
<div id="m3">
    <div id="heading">
        Please confirm
    </div>  
</div>
