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

For some reason the "".replace() method only replaces the first occurrence and not the oth开发者_开发百科ers. 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.

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

if you don't require the power of RegExp

str.replace(/\//g,”_”)

Try this code:

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