在每行文字中添加字符？ [英] Add character to every line of text?

问题描述

我有一个函数，它从数据库中获取一段文本并将其放入textarea中，我试图在数据库中取出的非常行的文本旁边放置一个像''>'这样的符号。放入textarea来显示它从数据库中获取，任何人都可以帮忙吗？

I have a function that takes a piece of text from the database and puts it into a textarea, I''m trying to put a symbol like ''>'' beside very line of text thats taken from the database and put into the textarea to show its taken from the database, can anyone help?

推荐答案

如果你已经定义了行数，那么你可以在每个行之前添加（行） ？2）字符你的指标> "。

if you have defined the number of rows, then you can add before every (rows ? 2) characters your indicator "> ".

问题是，它是一个textarea，当第一行填充时，它会转到下一行，所以我不知道它何时会进入下一行！ ？

The problem is, its a textarea and when the first line is populated it goes to the next line so i don''t know when it will go to the next line!?

您好。


首先，您不能放置符号>进入HTML输出而不会导致各种问题。这是一个保留字符。

使用HTML符号& gt;代替。 （没有引号。）


我不太明白你想要在这里完成什么。

你想要把> "在你的文本框里面的每一行之前？

如果是这样，请尝试在每个换行符之后添加HTML符号。
（替换所有出现的内容） \ n和\ n& gt;应该这样做。再次，没有引号）


如果没有，请详细说明。

Hi.

First of all, you can not put the symbol ">" into your HTML output without causing all sorts of problems. It is a reserved character.
Use the HTML symbol ">" instead. (Without the quotes.)

I''m not quite getting what you are trying to accomplish here.
Do you want to put ">" before every line of text inside your textbox?
If so, try adding the HTML symbol after each new-line character.
(Replacing all occurences of "\n" with "\n>" should do that. Again, without the quotes)

If not, please elaborate.
Remember, we like code examples and error messages ;]
