Replace all instances of character in javascript

Question

I have a string

 var str=  'asdf<br>dfsdfs<br>dsfsdf<br>fsfs<br>dfsdf<br>fsdf';

I want to replace   with \r by using

 str.replace(/<br>/g,'\r');

, but it is replacing only the first  ... Any idea why?

replace(/ /g,'\r') replaces all   here ... Or did you only want to replace the first  ? — KooiInc

Something else must be going on. The code snippet you pasted does what you want. Here's the output from node.js:` 'asdf dfsdfs dsfsdf fsfs dfsdf fsdf'.replace(/ /g,'\r') = 'asdf\rdfsdfs\rdsfsdf\rfsfs\rdfsdf\rfsdf'` — odrm

This should work, have you made sure this is the original code? — Kevin

The code should work - with the /g flag, it should replace all  s. It's possible the problem is elsewhere.

Try this:

str = str.replace(/<br>/g, '\n');

'\n' is probably more appropriate than \r - it should be globally recognized as a newline, while \r isn't common on its own. On Firefox, for example, \r isn't rendered as a newline.

Use :

str.replace(/<br>/gi,'\r');

/g is only for the first match. /gi is for global replacement
