Question

我正在创建一个具有图像网格的网站。我希望每个图像在单击时扩展为模态。我已经用它来处理一个图像，但我必须为每个图像创建一个新的模态，新的myImg和新脚本。无论如何我可以只有一个模态和一个myImg，并编写一个脚本，使其通常适用于每个图像，这样我就不必为每个图像创建一个新的模态和myImg，因为这将很快变得荒谬。

网格示例：

源代码：

<!DOCTYPE html>

<html>
    <?php
        $myfile = fopen("header.html", "r") or die("Unable to open file!");
        echo fread($myfile,filesize("header.html"));
        fclose($myfile);
    ?>
    <style>
        .img {
            font-size: 0;
        }

        a1 {

Answer 1

使用Jquery获取点击的img的id和信息，并使用id和info参数创建模态的函数，并将点击的img的id和信息传递给函数，然后将它们添加到vars ex：

<code>

所以这将是动态的。
