wordpress - 如何将自动换行属性添加到 SyntaxHighlighter Evolved v.3x

问题描述

我正在使用 SyntaxHighlighter Evolved v.3x 在 Wordpress 上突出显示我的代码。在 v.3x 版本中不支持自动换行。我怎样才能做到自动换行？我必须使用 v.3x，因为我讨厌闪光灯。我篡改了一些代码，但我什么也得不到。

解决方案

当您使用 Syntaxhighlighter Evolved 插件时，它实际上会为您生成如下 HTML 代码：

<div id="highlighter_810026" class="syntaxhighlighter php">
   <table cellspacing="0" cellpadding="0" border="0">
      <tbody>
         <tr>
            <td class="gutter">
               <div class="line number1 index0 alt2">1</div>
               <div class="line number2 index1 alt1">2</div>
               <div class="line number3 index2 alt2">3</div>
               <div class="line number4 index3 alt1">4</div>
               <div class="line number5 index4 alt2">5</div>
               <div class="line number6 index5 alt1">6</div>
               <div class="line number7 index6 alt2">7</div>
               <div class="line number8 index7 alt1">8</div>
               <div class="line number9 index8 alt2">9</div>
               <div class="line number10 index9 alt1">10</div>
               <div class="line number11 index10 alt2">11</div>
               <div class="line number12 index11 alt1">12</div>
               <div class="line number13 index12 alt2">13</div>
               <div class="line number14 index13 alt1">14</div>
               <div class="line number15 index14 alt2">15</div>
            </td>
            <td class="code">
               <div class="container">

               </div>
            </td>
         </tr>
      </tbody>
   </table>
</div>

当你分析代码时，你会看到类中gutter的行号和类中的行号container是相同的。因此，当您等于线高时，问题将得到解决。为此，我找到了如下解决方案：

jQuery(window).on('load', function() {
    jQuery(".syntaxhighlighter .gutter .line").each(function(index, element) {
        var divs = jQuery('.code .container .line');
        jQuery(this).attr("style", "height:" + divs.eq(index).height() + "px!important;");
    });
});

我建议您将代码放在主题内的可自定义 javascript 文件中，这样它就不会受到更新的影响。

我不知道是否有更好的解决方案。但问题似乎来自创建一个单独的guter类。相反，最好在container类中添加行号。但我不知道这有多难。但结果，问题似乎得到了解决。
