如何创建模态图像网格？
[英]How to create a grid of modals images?
问题描述
我正在创建一个以图像网格为特色的网站。 我希望每个图像在单击时都展开为模态。 我已经将其与一个图像一起使用，但是我必须为每个图像创建一个新的模式，新的myImg和新的脚本。 无论如何，我只能拥有一个模态和一个myImg并编写脚本以使其通常可用于每个图像，这样我就不必为每个图像创建新的模态和myImg，因为那样很快就会变得很长。
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 {
font-size: 16px;
display: inline-block;
margin-bottom: 8px;
width: calc(50% - 4px);
margin-right: 8px;
}
a1:nth-of-type(2n) {
margin-right: 0;
}
@media screen and (min-width: 50em) {
a1 {
width: calc(25% - 6px);
}
a1:nth-of-type(2n) {
margin-right: 8px;
}
a1:nth-of-type(4n) {
margin-right: 0;
}
}
img {
border: none;
max-width: 100%;
height: auto;
display: block;
background: #ccc;
transition: transform .2s ease-in-out;
}
figure {
margin: 0;
overflow: hidden;
}
/* The Modal (background) */
.modal {
display: none; /* Hidden by default */
position: fixed; /* Stay in place */
z-index: 1; /* Sit on top */
padding-top: 100px; /* Location of the box */
left: 0;
top: 0;
width: 100%; /* Full width */
height: 100%; /* Full height */
overflow: auto; /* Enable scroll if needed */
background-color: rgb(0,0,0); /* Fallback color */
background-color: rgba(0,0,0,0.9); /* Black w/ opacity */
}
/* Modal Content (image) */
.modal-content {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
}
/* Caption of Modal Image */
#caption {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
text-align: center;
color: #ccc;
padding: 10px 0;
height: 150px;
}
/* The Close Button */
.close {
position: absolute;
top: 15px;
right: 35px;
color: #f1f1f1;
font-size: 40px;
font-weight: bold;
transition: 0.3s;
}
.close:hover,
.close:focus {
color: #bbb;
text-decoration: none;
cursor: pointer;
}
/* 100% Image Width on Smaller Screens */
@media only screen and (max-width: 700px){
.modal-content {
width: 100%;
}
}
#myImg {
border-radius: 5px;
cursor: pointer;
transition: 0.3s;
}
#myImg:hover {opacity: 0.7;}
#myImg2 {
border-radius: 5px;
cursor: pointer;
transition: 0.3s;
}
#myImg2:hover {opacity: 0.7;}
</style>

使用Jquery来获取单击的img的ID和信息，并使函数使用id和info参数创建模态，然后将单击的img的ID和信息传递给函数，然后将其添加到vars ex：
var modalImg = document.getElementById("img" + imgIdNumber);
etc...
因此它将是动态的。
