Javascript 如何设置模式弹出多个图像

Javascript 如何设置模式弹出多个图像,javascript,html,css,magento-1.9.2.4,Javascript,Html,Css,Magento 1.9.2.4,我尝试使用此功能在模式弹出窗口中显示多个图像: //获取模式 var modal=document.getElementById('myModal'); //获取图像并将其插入模式-使用其“alt”文本作为标题 var img=document.getElementById('myImg'); var modalImg=document.getElementById(“img01”); var captionText=document.getElementById(“caption”); im

img.onclick=函数(){
modal.style.display=“块”;
modalImg.src=this.src;
captionText.innerHTML=this.alt;
}
//获取关闭模态的元素
var span=document.getElementsByClassName(“关闭”)[0];
//当用户单击(x)时,关闭模式对话框
span.onclick=function(){
modal.style.display=“无”;
}

此实现将不起作用,因为您正在通过ID引用同一DOM元素。您可以尝试使用此JSFIDLE创建多图像模式。这对您来说也更容易实现


下面是一个放大弹出窗口的示例:

我找到的最佳解决方案:

首先,HTML更改:

例: 每个图像都需要自己的ID。。。对您的html进行非常小的更改。。。(从w3school.com更改为原始文件

<div class="image"><img **id="myImg2"** src="images/pic02.jpg" alt="" /></div>
<div class="image"><img **id="myImg3"** src="images/pic03.jpg" alt="" /></div>
原创的

    <div class="image"><img **id="myImg" src="images/pic01.jpg" alt="" /></div>
    #myImg {
        border-radius: 5px;
        cursor: pointer;
        transition: 0.3s;
    }

    #myImg:hover {opacity: 0.7;}

----
Javascript更改: 增加了以下内容: 为每个图像添加var“变量”,并为每个图像添加“单击”功能: --- 例:

原始的

<script>
    // Get the modal
var modal = document.getElementById('myModal');

// Get the image and insert it inside the modal - use its "alt" text as a caption
var img = document.getElementById('myImg');
var modalImg = document.getElementById("img01");
var img2 = document.getElementById('myImg2');
var img3 = document.getElementById('myImg3');
var captionText = document.getElementById("caption");
img.onclick = function(){
    modal.style.display = "block";
    modalImg.src = this.src;
    captionText.innerHTML = this.alt;
}

//handle click for myImg2
img2.onclick = function(){
    modal.style.display = "block";
    modalImg.src = this.src;
    captionText.innerHTML = this.alt;
}

//handle click for myImg3
img3.onclick = function(){
    modal.style.display = "block";
    modalImg.src = this.src;
    captionText.innerHTML = this.alt;
}

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks on <span> (x), close the modal
span.onclick = function() { 
  modal.style.display = "none";
}
    </script>

//获取模态
var modal=document.getElementById('myModal');
//获取图像并将其插入模式-使用其“alt”文本作为标题
var img=document.getElementById('myImg');
var modalImg=document.getElementById(“img01”);
var img2=document.getElementById('myImg2');
var img3=document.getElementById('myImg3');
var captionText=document.getElementById(“caption”);
img.onclick=函数(){
modal.style.display=“块”;
modalImg.src=this.src;
captionText.innerHTML=this.alt;
}
//myImg2的句柄单击
img2.onclick=函数(){
modal.style.display=“块”;
modalImg.src=this.src;
captionText.innerHTML=this.alt;
}
//myImg3的句柄单击
img3.onclick=函数(){
modal.style.display=“块”;
modalImg.src=this.src;
captionText.innerHTML=this.alt;
}
//获取关闭模态的元素
var span=document.getElementsByClassName(“关闭”)[0];
//当用户单击(x)时,关闭模式对话框
span.onclick=function(){
modal.style.display=“无”;
}
下面是一个很容易理解的例子:

    transition: 0.3s;
}

#myImg3 {
    border-radius: 5px;
    cursor: pointer;
    transition: 0.3s;
}

#myImg:hover {opacity: 0.7;}

#myImg2:hover {opacity: 0.7;}

#myImg3:hover {opacity: 0.7;}
