按\\ n字符拆分似乎不起作用

Question

I'm getting a result from a server where items are separated with new lines, so I do a:

split('\n');
split('\\n');

It doesn't work! the \\ disappears while debugging on Chrome (I see split('n')).

How to make it work?

Sample data (copy from debugger of chrome):

"יופי וקוסמטיקה|10↵בידור ותרבות|9↵לילד ולתינוק|3↵תיירות|4↵תכשיטים|5"

Answer 1

If the result has the literal characters "\\n" in it, you need to escape your \\ .

split('\\n');

Another possibility is that you have \\r\\n sequences in the string. If so, do this:

split('\r\n');

...although the .split('\\n') should still work.

Or if it is sending them with just \\r sequences, you'd do:

split('\r');

If you're not sure, do this:

split(/\r\n|\n|\r/);

Answer 2

I tried it with split("\\n") and it is working.

The choice of double or single quotes will make a difference in the way that Ruby treats the contents.

Answer 3

if you have '↵' character in your paragraph,

Firstly you must replace '↵' character to '\\n' then

and if you have web project

you must use 'white-space: pre-line' in your css code.

I have some problem when I get paragraph from database paragraph coming with '↵' character and it not add new line in paragraph I used this solution for this problem.

Answer 4

我在一个在模板引擎下运行的页面上工作，它从“ \\n ”中删除了“ \\ ”。
