The reason why mysql output data is assigned to js variable and unterminated string literal error occurs_javascript skills

Read certain text data from mysql and pay it to js variables such as

Copy code The code is as follows:

But I found that the unterminated string literal error was always reported under Firefox. Copy that text to txt and open it. You will find several black squares. It turns out that they are mysql line break marks. n, in txt it cannot be displayed correctly because it uses double bytes, so 2 black squares are displayed.

Solution: When returning this data from the server, remove rn

$value=str_replace("rn","",$value)
