單擊圖片鏈接時如何更改Div的內容？

Question

我正在創建具有兩個列的布局。

一個具有圖像和第二個內容。 現在我想，每當用戶單擊圖像時，第二列中的內容都會更改。

HTML

    <div class="col-sm-6">
            <div class="row" style="width: 75%;margin: 0 auto;">
             <div class="col-xs-6">
                <a href="#" class="p1"><span id="image1"><b>Planning</b></span></a>
             </div>
             <div class="col-xs-6">
                <a href="#" class="p2"><span id="image2"><b>Results</b></span></a>         
             </div>
           </div><br>
           <div class="row" style="width: 75%;margin: 0 auto;">
             <div class="col-xs-6">
                <a href="#" class="p3"><span id="image3"><b>Improvements</b></span></a>            
             </div>
             <div class="col-xs-6">
                <a href="#"  class="p4"><span id="image4"><b>Communication</b></span></a>              
             </div>
           </div>
<div class="st">
            <div class="planning">
            <h3>Planning</h3>

            </div>

            <div class="improvements">
            <h3>Improvements</h3>

            </div>

            <div class="communication">

            </div>              
          </div>
    <div class="col-sm-6 how-text">

    </div>

CSS

.st { display:none; }
.how-text { min-height: 300px;
    height: auto;
    background-color: #e6ebe4; 
    padding: 20px;
    margin: 25px 0px 10px 0px;
    border-radius: 3px; }

jQuery的

$(document).ready(function() {
   $('.p1').click(function(){
    $('.how-text').html($('.planning').html());
});

    $('.p2').click(function(){
    $('.how-text').html($('.results').html());
});

    $('.p3').click(function(){
    $('.how-text').html($('.improvements').html());
});

    $('.p4').click(function(){
    $('.how-text').html($('.communication').html());
});
});

Answer 1

Editted

這是最簡單的方法

getElementsByClassName

我更改了您的代碼以供您理解

工作實例

Answer 2

您可以在div內部訪問，因為它沒有顯示。 您可以使用

.st {height:0;overflow:hidden;}

而不是顯示：無

它可以是您的解決方案

Answer 3

您沒有在代碼中添加jquery。 另外，您可以將4個點擊事件的范圍縮小為單擊事件：

 $('a').click(function () {
   $('.how-text').html($('.st div:eq('+$('.row > div').index($(this).parent())+')').html());
 });
