如何在点击图片 link 时更改 Div 的内容？

Question

我正在创建一个包含两列的布局。

一个有图像和第二个内容。现在我想要，每当用户点击图像时，第二列中的内容就会发生变化。

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">

    <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

$(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

您没有在代码中添加 jquery。您也可以将 4 个点击事件缩小为单次点击事件：

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

Working Demo

Answer 2

您可以访问 div 的内部，因为它显示 none。你可以使用

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

而不是display:none

这可能是您的解决方案
