javascript - 如何动态加载模态

Question

您好，我想知道如何在不同的图像上动态加载模态。这是我当前的网页。

假设当我点击 life of pi 图像时，这是弹出的模态。

我希望其他图像也能发生同样的事情。假设如果我单击“追风筝的人”图像，它会打开一个模式，左侧是追风筝的人图像，右侧是文本。

这是我当前的代码

$(document).ready(function() {
      var $modal = $("#myModal");
      $("#lifeofpi").click(function() {
        $modal.show();
      });
      $modal.find('.close').click(function() {
        $modal.hide();
      });
    });

/* 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(0,0,0,0.7); /* Black w/ opacity */
}

/* Modal Content */
.modal-content {
background-color: #fefefe;
margin: auto;
padding: 20px;
border: 1px solid #888;
width: 700px;
height: 500px;
background-color: #101010;

}


/* The Close Button */
.close {
color: #aaaaaa;
float: right;
font-size: 28px;
font-weight: bold;
}

.close:hover,
.close:focus {
color: #000;
text-decoration: none;
cursor: pointer;
}

  

.modallifeofpi {
 cursor: pointer;
 height: 160px; // height
 //width: 30%; // width
 border: 5px solid white;
 display: inline;
 margin-top:0px;
 position: absolute;
 }


 .modalheader {
 color:white;
 margin:0;
 margin-left: 470px;

 }

 .modalheadertext {
 color:white;
 margin-left: 350px;
 margin-top:40px;
 }
  
 .review-img {
  cursor: pointer;
  height: 160px; // height
  //width: 30%; // width
  }

您可以只绑定(bind)所有图像并将图像信息传递给模态。

$(document).ready(function() {
      var $modal = $("#myModal");
      $(".images img").click(function() {
    $modal.find('img.modallifeofpi').attr('src',$(this).attr('src'));
    $modal.find('.modalheader').text($(this).attr('alt'));
    $modal.show();
});
$modal.find('.close').click(function() {
    $modal.hide();
});
    });

/* 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(0,0,0,0.7); /* Black w/ opacity */
}

/* Modal Content */
.modal-content {
background-color: #fefefe;
margin: auto;
padding: 20px;
border: 1px solid #888;
width: 700px;
height: 500px;
background-color: #101010;

}


/* The Close Button */
.close {
color: #aaaaaa;
float: right;
font-size: 28px;
font-weight: bold;
}

.close:hover,
.close:focus {
color: #000;
text-decoration: none;
cursor: pointer;
}

  

.modallifeofpi {
 width: 300px;
 height: 450px;
 border: 5px solid white;
 display: inline;
 margin-top:0px;
 position: absolute;
 }


 .modalheader {
 color:white;
 margin:0;
 margin-left: 470px;

 }

 .modalheadertext {
 color:white;
 margin-left: 350px;
 margin-top:40px;
 }
  
 .review-img {
  cursor: pointer;
  height: 160px; // height
  //width: 30%; // width
  }
