javascript - 如何为所有模式制作一个脚本？

问题描述

在同一页面上，我有大约十几个图像，并且在每个图像上单击时您会打开一个模态。我为每个模态制作了一个脚本，如何为所有模态制作一个脚本？

<!-- 1 Modal-->

<script>
   var undici = document.getElementById('lele');
   var lele = document.getElementById("img11");

function myLele(el) {
        var ImgSrc = el.src;
        undici.style.display = "block";
        lele.src = ImgSrc;
    }
    window.onclick = function (event) {
        if (event.target == undici) {
            undici.style.display = "none";
        }
    }
</script>
<script>
    var dieci = document.getElementById('jessy');
    var jessy = document.getElementById("img10");

function myJessy(el) {
        var ImgSrc = el.src;
        dieci.style.display = "block";
        jessy.src = ImgSrc;
    }
    window.onclick = function (event) {
        if (event.target == dieci) {
            dieci.style.display = "none";
        }
    }
</script>

我尝试了不同的方法，但不是在同一页面上的多个模式上不起作用。我可以做一个 foreach () 循环吗？

解决方案

每个元素的 ID 应该是唯一的。将两个图像的 ID 从 分别更改为myImg独特的myImg1和myImg2。

此外，您不需要编写自定义函数来切换模式。data-toggle="modal" data-target="#lele"只需通过添加到模态 1 图像和模态 2 图像中来使用 Bootstrap 中的内置模态，data-toggle="modal" data-target="#jessy"如下所示：

<img src="/leletronika.jpg" id="myImg1" class="img-responsive" data-toggle="modal" data-target="#lele">
<img src="/jessy.jpg" id="myImg2" class="img-responsive" data-toggle="modal" data-target="#jessy">

您还需要将data-dismiss属性添加到关闭按钮，如下所示：

<span class="close" data-dismiss="modal">&times;</span>

检查并运行以下代码片段，以获得我上面描述的实际示例：

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.0/umd/popper.min.js"></script><script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="stylesheet"/>
