Javascript 在网页中显示长文本区域注释的步骤

我有一个由用户输入的长文本区注释。为了将它正确地包装在我的JSP中，我使用下面的代码<代码>评论区是我的文本区：

function addNewlines(commentarea) {

  var result = '';
  while ($.trim(commentarea).length > 0) {
    result += $.trim(commentarea).replace(/[\s\n\r]+/g, ' ').substring(0, 40) + '\n'; commentarea= $.trim(commentarea).replace(/[\s\n\r]+/g, ' ').substring(40);
  }
  return result;
}

文本正在被包装，但问题是单词之间有40个字符长的空格。例如，在我的输出中，我得到一个介于

programmable

和

simple

hello world today this is a simple prog rammable hello world today this is a sim ple prog rammable

---

或者你最好用“单词包装”来代替这个…参考这个

---

不需要任何循环就可以用单个空格替换所有空格和换行符

commentarea.value = commentarea.value.replace(/\s+/g, ' ').substring(0, 40);

你确定你应该在一个while循环中这样做吗？是的，否则我不会得到完整的答案sentence@tina，请增加更多的精确性，因为我们似乎都未能正确理解您的问题。从我在您的代码中看到的内容来看，我看到有人试图从中删除所有多个空格和换行符，并且已经为此提供了解决方案。如果这不是你想要达到的，试着用另一种方式解释。谢谢让我们考虑一下，如果我粘贴长注释，在StAdExobe中添加注释区QQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJWWWWWWWWWWWWWWWWWWWWWWWWWWW如果我不使用，我怎样才能得到完整的句子loops@tina，你说的“整句话”是什么意思

commentarea.value

包含

textarea

的全部内容。你不必

将内容拆分成句子，并单独处理它们，只需去除换行符和多个空格，除非在你试图实现的目标中有我不理解的东西。
