Replace a specific set of characters using JavaScript only

Question

I have an RTF string that contains \*\revtbl{Unknown;}}, it is used to indecate that the word that follows is misspelled (I think) and I need to remove it, when I do:

.replace(/{\*\revtbl{Unknown;}}/g, "")

I get two lines:

*
evtbl{Unknown;}}

When I change to:

.replace(/{\*\r|evtbl{Unknown;}}/g, "")

I get just the * and a second line. e.g.:

var tt = '\*\revtbl{Unknown;}}';
tt=tt.replace(/{\*\r|evtbl{Unknown;}}/g, "");
alert('"'+tt+'"');

I see:

"*
"

I could not find any reference about the use of the pipe | character so I need to know: if by using it am I asking to replace two separate strings one being {\*\r and the other being evtbl{Unknown;}} bottom line I need to replace the literal string \*\revtbl{Unknown;}} with nothing.

I think it is just a matter of escaping all the characters correctly

//sample string - NOTE: the backslashes had to be escaped for JS
var str = "RTF string that contains \\*\\revtbl{Unknown;}}, it is used to indecate that the word that follows is misspelled (I think) and I need to remove it, when I do:";

var regEx = /\\\*\\revtbl\{Unknown;\}\}/g;

console.log(str.replace(regEx, ''));

Thank you for your reply, when I do tt = '\\*\\revtbl{Unknown;}}'; as you have done this works, however, the actual "literal" string is \*\revtbl{Unknown;}}. The RTF is imported, not entered so I cannot change it - thanks.

Is the literal string hard coded into your JS as a string or is it coming from a variable? If the value is just hard coded as a string you have to escape the backslash. For example if you do: console.log('\*\\revtbl{Unknown;}}') you will see that you aren't getting the double slashes

It's in a variable that is loaded from an xml file, so it is "literally", "exactly", "specifically" \*\revtbl{Unknown;}} - thanks.

It does not work, please show me how - thanks. I have t='{\*\revtbl{Unknown;}}' how do I remove it - thanks.

If that is what the string is going to be when loaded from your file, then you would want to use: var regEx = /\{*\revtbl\{Unknown;\}\}/g;
