如何让 PHP 回显“\n”作为 javascript 的纯文本并且没有“\n”创建新行？

Question

PHP is echoing JavaScript (I'm using the jQuery library) something like this:

echo 'var users = $("#add").val().split("\n");';

However, the \n is creating a line break in what the echoed script looks like, and therefore breaking the JavaScript. Is there a way to circumvent this?
Many thanks!

Answer 1

The \n is an escape sequence meaning newline. Backslashes are the beginning of escape sequences, to output a backslash then write \\ . So you want \\n . Other useful escape sequences include the quote: use \" to put a quote into the string instead of ending the string.

Answer 2

echo "var users = $(\"#add\").val().split(\"\\n\");";

Answer 3

Not sure If you looking for this

echo "<script>alert('Line1\\\\nThis still in Line1')</script>";
