仅使用JavaScript替换一组特定的字符

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. eg:

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.

Answer 1

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, ''));
