Replace all occurances in javascript

Question

I've searched through different websites showing me the way to replace strings in js. But actually its not working! Why?

The code I'm using:

var str = "This is html. This is another HTML";
str = str.replace('/html/gi','php');

Output: This is html. This is another html

Nothing is changing. Its Frustrating!

No quotes:

str = str.replace(/html/gi,'php');

The RegExp object can be expressed in its literal format:

/I am an actual object in javascript/gi

Thanks for this idea. I didn't knew it is valid in js!! – Sukanta Paul Oct 22 '12 at 14:31
@SukantaPaul Actually, the RegEx MUST be expressed unquoted... However you can write `replace` in string-format. – Christoph Oct 22 '12 at 14:35
@Christoph, thanks for clearing that up. I was referencing `new RegExp()`. However, it wasn't clearly stated in my answer. – Joe Oct 22 '12 at 15:03

remove the quotes to make it work. // is a regex and may not be quoted.

str = str.replace(/html/gi,'php');

Alternatively you could write:

str = str.replace(new RegExp('html','gi'),'php');

The non standard conform method would be this (works only in some browsers, not recommended!)

str.replace("apples", "oranges", "gi");

Remove the single quote from your regular expression like so:

var str = "This is html. This is another HTML";
str = str.replace(/html/gi,'php');

str = str.replace(/html/, 'php');

you shouldn't put single or double quotes for the first parameter.
