单击按钮时显示更多信息html，css，javascript

-1

我写了一个代码，其中有一个框，当我单击该按钮时，它实际上会显示更多或更少的信息。看到它在行动这里：https://jsfiddle.net/075tcezL/单击按钮时显示更多信息html，css，javascript

/css 
#model { 
width: 300px; 
border: 1px solid #c1c1c1; 
margin: 20px 10px; 
padding: 0 5px; 
float: left; 
max-height: 300px; 
overflow: hidden; 


-webkit-transition: max-height 0.7s; 
-moz-transition: max-height 0.7s; 
transition: max-heigth 0.7s; 

} 
#show-more { 
display: block; 
background-color: #75868E; 
width: 100px; 
font-size: 12px; 
text-transform: uppercase; 
display: inline-block; 
margin: 20px auto; 
cursor: pointer; 
height: 15px; 
padding: 10px 0; 
} 

#model.open { 
max-height: 1000px; 

-webkit-transition: max-heigth 0.7s; 
-moz-transition: max-heigth 0.7s; 
transition: max-heigth 0.7s; 
}

// HTML

<body> 
<div id="model" class="model1"> 
    <h3>Series 3</h3> 
     <a href="#series3" id="sseries"><img class="image" 
      src="image"></a> 

<p>Text to hide or show.</p> 

</div>      
<a id="show-more" class="show">Show More</a> 

<script src="javascript.js"></script> 

</body>

//这适用于一个盒子

var content = document.getElementById("model"); 
var button = document.getElementById("show-more") 

button.onclick = function(){ 

if(content.className == "open"){ 
    content.className = ""; 
    button.innerHTML = "More"; 

} else { 
    content.className = "open"; 
    button.innerHTML = "Less"; 
} 

};

但如果我有三个箱子，这样的 - https://jsfiddle.net/jw7pfb1w/ 点击该按钮时，如何同时打开或关闭它们？

任何帮助，将不胜感激！

您需要在这里放置问题代码的你最小的例子，不是的jsfiddle可以改变或消失明天帮助中没有一个未来：https://stackoverflow.com/help/mcve – Rob

您可以使用document.getElementsByClassName('.model1');来选择页面上的所有元素具有相同等级：

var content = document.getElementsByClassName("model1"); 
var button = document.getElementById("show-more"); 

button.onclick = function(){ 
    for (i = 0; i < content.length; ++i) {  
     if(content[i].className == "model1 open"){ 
     content[i].className = "model1"; 
     button.innerHTML = "More"; 
    } else { 
     content[i].className = "model1 open"; 
     button.innerHTML = "Less"; 
    } 
    } 
};

您还需要为open的CSS在3面板例如：

div.open { 
    max-height: 1000px; 
    -webkit-transition: max-heigth 0.7s; 
    -moz-transition: max-heigth 0.7s; 
    transition: max-heigth 0.7s; 
}

为您更新。您可能希望查看jQuery，因为这可以使这种UI功能更容易。 – mjw

你可以使用相同的方法三次，或做一个循环。

为了达到这个目的，你可以在你的html中添加多个带数字的id。像模型1，模型2，model3，...

var button = document.getElementById("show-more") 
 

 
button.onclick = function(){ 
 

 
\t // we loop three times for three blocks 
 
\t for (var i = 0; i < 3; i++) { 
 
    // i + 1 -> 1, 2, 3 
 
    // so model1, then model2, then model3 
 

 
    // using concatenation string "model" + the number 
 
    var content = document.getElementById("model" + (i + 1)); 
 

 
    // using toggle function will add the class if not present, else remove it. 
 
    var isOpen = content.classList.toggle('open'); 
 

 
    button.innerHTML = isOpen ? "More" : "Less"; 
 
    } 
 

 
};

.model { 
 
\t width: 100px; 
 
\t border: 1px solid #c1c1c1; 
 
\t margin: 20px 10px; 
 
\t padding: 0 5px; 
 
\t display: inline-block; 
 
\t max-height: 100px; 
 
\t overflow: hidden; 
 
} 
 

 
.open { 
 
\t max-height: 1000px !important; \t 
 
}
