Question

我最近在Bootsrap 3中遇到过模态问题。

我正在测试一个测试网站（不是我实际上放在网上的任何东西）并且有3张图片（每张图片在col-md-4中）彼此相邻，我打算让一个按钮居中在每张图片下，可以点击一个模式以显示更多信息。

我设置了第一个完美的模态然而，当我添加第二个时，我发现当你点击任一按钮时，两个模态都显示在彼此之上（第二个是第一个），当你按下“返回主页”时，它会转到另一个模态

你只能按“X”一两次回家。

我几乎可以肯定这是因为<head>中的JavaScript非常不正确，但我不是很擅长JS而且不知道我做错了什么......

这是html所以你可以检查我的手工作品：

Answer 1

这是因为您正在使用.btn（两个按钮上共享的公共类）来触发模态。因此，当您点击任何.btn时，它会触发两个模态。

要么添加一个类/ id，要么使用单击处理程序上的data-target属性来激活相应的模态，或者由于你的按钮位于html中的模态元素之前，你只需使用单击处理程序使用$('.btn')并通过$(this).next().modal()触发模态。

Answer 2

1）即使您使用内联javascript，也无需定义<script>代码两次

2）代码中的这一行表示，只要DOM中的某个元素具有类＆＃39; btn＆＃39;单击它将执行一个功能（在你的情况下打开一个模态）。你正在聆听＆＃b; btn＆＃39;元素＆＃39;点击活动。

 $(".btn").click(function(){

您可以为每个模态类型的每个按钮指定一个不同的类。例如，

<script type="text/javascript">

    <button type="button" class="btn btn-primary btn-chimecho" data-toggle="modal" data-target="#chimecho">

    <button type="button" class="btn btn-primary btn-eevee" data-toggle="modal" data-target="#eevee">


     $(function(){
       $(".btn-chimecho").click(function(){
           $("#chimechoModal").modal('show');
         });
       $(".btn-eevee").click(function(){
           $("#eeveeModal").modal('show');
         });

     });

</script>

多个模态卡在循环中，Bootstrap
