对于任何struggles 具有pasting 或使用formatted <pre> code 在里面Visual editor. 这个解决方案已经为我工作了很多年，and I love it. 这种方法使用“中间人”在编辑和wpautop() 前端。
只需粘贴到函数中即可。php
这看起来很重，但这就是为什么jQuery在与tinMCE API对话时必须在全局范围内的原因。多拉设计$ 无法使用和the jQuery text clutter the code down. 主要是创建占用空间的HTML元素。
How it works: 非常简单，不用“触摸”它-不要弄乱它。值得一试！

这种方法
is not a hack 或者一种陈腐的preg match解决方案。它生成与默认API相同的转换。
The PUSH cleanup 如果粘贴来自PHP类或其他类的代码，并且想要呈现的块或剪切掉的函数“之前”有很多空间或选项卡，则可以使用。它计算第一条现有直线上的空间。
使其：
if(search_string){
var firstChar = search_string[0];
var remove = workspace.substr(0, workspace.indexOf(firstChar));
remove = "\\r\\n" + remove;
data = ua_TinyMCE_helper_cleanBeginnings(data, remove, "\\r\\n");
}
对此：
if(search_string){
var firstChar = search_string[0];
var remove = workspace.substr(0, workspace.indexOf(firstChar));
remove = "\\r\\n" + remove;
data = ua_TinyMCE_helper_cleanBeginnings(data, remove, "\\r\\n");
}
B.T.W, 它有一个方便的
focus button, 显示在编辑器的右下角，在处理大量
<pre> 代码块。关闭屏幕设置“启用全高编辑器和无干扰功能”为了更好的UI。
