How do I replace all occurrences of "/" in a string with "_" in JavaScript?

Question

For some reason the "".replace() method only replaces the first occurrence and not the others. Any ideas?

You have to use the g modifier (for global) in your replace call.

str = str.replace(/searchString/g, "replaceWith")

In your particular case it would be:

str = str.replace (/\//g, "_");

Note that you must escape the / in the regular expression.

You may also need the "m" option for a multiline string. – Eric Wendelin Jan 29 '10 at 01:15

To make it more clear for the given problem: `str = str.replace (/\//g, "_");` – Thomas Eding Jan 29 '10 at 01:16

"Your/string".split("/").join("_")

if you don't require the power of RegExp

Interesting that this answer contains the same Microsoft "smart quotes" as were originally in Mayra's answer. – Lightness Races in Orbit Jun 15 '11 at 16:53

Try this code:

 text = text.replace(new RegExp("textToReplace","g"), "replacemntText"));
