如何在textarea中显示换行符？ [英] How to show newlines from textarea in a table?

问题描述

在一个表单中，我有一个textarea，在那里明显地输入文本。当输入完成后，内容被提交到服务器并存储在数据库中...

是否有可能在该表格中显示换行符？
我知道，可能是一个非常愚蠢的问题，但我不会亲，当涉及到像HTML和CSS的东西......

解决方案

\\\
不会在HTML中呈现为新行。您必须使用< br /> 才能达到此效果。

使用替换字符串替换所有'\ n'个字符转换为'< br /> '

如果 ，您正在使用像 C＃ 这样的服务器端语言，那么您可以执行此操作。

 私人字符串PutLineBreaks（字符串strData）
 {
字符串strReplaced = string.Empty; 
 
 Regex r = new Regex（/ \\\
 / g）; 
 
 strReplaced = r.Replace（strData，< br />）; 
 
返回str替换; 
} 
  

In a form I have a textarea where obviously text is entered. When the input is finished the content gets submitted to the server and is being stored in a database...

When I display the input the user made within a table, the newlines are not visible. When I inspect the source the newlines are there, but within a table the newlines do not work...

Is there any possibility of displaying the linebreaks within that table? I know, probably a really silly question but I'm not to pro when it comes to things like html and css...

Any help is really appreciated!

解决方案

\n won't be rendered as a new line in HTML. You have to use a <br/> to achieve this effect.

Use a string replace to replace all '\n' characters to '<br/>'

If you are using a server side language like C# you can do this

private string PutLineBreaks(string strData)
{
    string strReplaced = string.Empty;

    Regex r = new Regex("/\n/g");

    strReplaced = r.Replace(strData, "<br/>");

    return strReplaced;
}
