Replacing "this" with "this"...

**pcbrainbuster** · 04-12-2007, 06:05 PM

Hello again guys

,

Sometimes when a user types down something you may need to replace certain characters/words with others, eg -

<html>
<body>
<input type="text" id="tbox">
</body>
</html>

Say tbox's value was c:\document and settings\john\desktop\, what script/method would you use to replace every instance of \ with?

Thanks

to replace all backslashed with forward slashes

Code:

string.replace(/\\/g,"/")

/ / = regular expression
\\ is an escaped backslash
g means gloablly (All occurances)

Hmm.. it seems pcbrainbuster hasn't specified what he/she wants to replace \ with. The above regex does work, we just need to know what to replace \ with.

Replace it with !... And can't it be done without regex???!!!

**mburt** · 04-12-2007, 06:35 PM

Er... replace it with what, an exclamation point?

And can't it be done without regex???!!!

Believe me, doing it without regular expressions would be much more complicated.

Yup, replace it with ! (remember that is to be used as an example and its not practical...), I don't understand regex (yet) so can I see the normal way of doing it (without regex)...

Thanks

Sorry, but there is no "normal" way of doing it. The replace method's arguments are regular expression strings only.

Neverming I searched how to do it and now can do it...

Code:

<script type="text/javascript">
// <![CDATA[

function replaceIt() {
	str = "I want to replace &#92 with a !";
	newStr = str.replace("&#92", "!");

	document.write("<b>String:</b> " +str + "<br /><b>Result:</b> " + newStr);
}

// ]]>
</script>

Result is

Code:

String: I want to replace \ with !
Result: I want to replace ! with !

sorry I got my code mixed up... using the replace method is alot faster then using regular expressions for simple tasks.

I think you can replace words (letters) with easy regex like /word/, but other characters like backslash require more complicted regex.
