UPDATE  I just came across a wonderful syntax design in JavaScript-ES6 called Template literals  What you want to do can be literally be done using    backtick or grave accent character    var foo    Bob is cool     In which case  foo      Bob nis ncool  is true   Why the designers decided that         can be left unterminated  but the         and         are illegal to have newline characters in them is beyond me   Just be sure that the targeting browser supports ES6-specified Javascript implementation    nbsp     P  S  This syntax has a pretty cool feature that is similar to PHP and many more scripting languages  namely  Tagged template literals  in which you can have a string like this   var a    Hello   b    World   console log  The computer says    a toUpperCase        b         Prints  The computer says HELLO  World

The query string that I used to to escape the new line character in JS   LOAD DATA LOCAL INFILE  Data csv  INTO TABLE DEMO FIELDS TERMINATED BY     ENCLOSED BY     LINES TERMINATED BY   r n  IGNORE 1 ROWS   This involves new ES6 syntax - Template Literals    and I tried changing   n  to   r n  and worked perfectly in my case   PS  This example is my query to upload CSV data into mysql DB

The reason it is not working is because javascript strings must be terminated before the next newline character  not a  n obviously   The reason  n exists is to allow developers an easy way to put the newline character  ASCII  10  into their strings   When you have a string which looks like this     Note lack of terminating double quote var foo    Bob    Your code will have a syntax error at that point and cease to run   If you wish to have a string which spans multiple lines  you may insert a backslash character     just before you terminate the line  like so     Perfectly valid code var foo    Bob   is   cool      However that string will not contain  n characters in the positions where the string was broken into separate lines  The only way to insert a newline into a string is to insert a character with a value of 10  the easiest way of which is the  n escape character   var foo    Bob nis ncool

I think they using  n anyway even couse it not visible  or maybe they using  r  So just replace  n or  r with  lt br  gt

I don t think you understand how  n works  The resulting string still just contains a byte with value 10  This is represented in javascript source code with  n   The code snippet you posted doesn t actually work  but if it did  the newline would be equivalent to  n  unless it s a windows-style newline  in which case it would be  r n   but even that the replace would still work

Check for  n or  r or  r n   There are several representations of newlines  see http   en wikipedia org wiki Newline Representations

This is a small adition to  Andrew Dunn s post above  Combining the 2 is possible to generate readable JS and matching output   var foo    Bob n      is n      cool  n
