I have the following string in JavaScript

 var mystring = " abcdef(p,q); check(x,y); cef(m,n);"

I would want to do a string replace such that my final string is :

 mystring = " abcdef(p,q); someothercheck\(x,y\); cef(m,n);"

x and y should remain same after the substitution. and the backslashes are necessary since I need to pass them to some other command.

There can be other Parantheses in the string too.

    Why a regex? Just string-replace " check" with " someothercheck" and "(" with "\(" and ")" with "\)". Commented Aug 13, 2011 at 14:57

    like mystring.replace('check','somothercheck').replace('(','\\(').replace(')','\\)'); jsfiddle.net/ytnRx Commented Aug 13, 2011 at 15:00
  • 3 regexes are better than one Commented Aug 13, 2011 at 15:02
  • I have edited the question . Please see that paranthses are present elsewhere and @stebs method won't work. Commented Aug 13, 2011 at 15:41

If you don't have other parenthesis, it should be easy. 

mystring = mystring.replace("check(", "someothercheck\\(");
mystring = mystring.replace(")", "\\)");

EDIT This works also in the case of multiple parenthesis (It does not affect the empty ones). var str=" abcdef; check(x,y); cef();" patt = /((\w)/g;

// transform (x in \(x
str = str.replace(patt, '\\(1ドル');
patt = /(\w)\)/g
// transform y) in y\);
str = str.replace(patt, '1ドル\\)');
// transform check in someothercheck
str = str.replace('check', 'someothercheck');

EDIT Now it converts only the check strings.

function convertCheck(str, check, someOtherCheck) {
 // console.log(str + " contains " + check + "? ");
 // console.log(str.indexOf(check));
 if (str.indexOf(check) === -1) return str;
 var patt1 = /\((\w)/g,
 patt2 = /(\w)\)/g; 
 str = str.replace(patt1, '\\(1ドル');
 str = str.replace(patt2, '1ドル\\)');
 str = str.replace(check, someOtherCheck);
 return str;
}
var str = "abcdef(); check(x,y); cef();",
 tokens = str.split(';');
for (var i = 0; i < tokens.length; i++) {
 tokens[i] = convertCheck(tokens[i], "check", "someothercheck");
}
str = tokens.join(";");
alert(str); // "abcdef(); someothercheck/(x,y/); cef();"

Don't take him literally. Consider someothercheck as an example
I have edited the question.There are other parantheses in the string too.
@Pablo, Don't take him (@user278064) literally. Consider the answer as an example.
@user270349 I am sorry my question wasn't clear ! I need to check it with the string : "func1(a,b,c); func2(a,v,b); check (x,y); cef(c,d)"
It wasn't me, it was @user278064

var myString = "abcdef; check(x,y); cef;";
myString.replace(/(\w+)\(/, 'someother1ドル(')
 .replace(/\(/g, '\\(')
 .replace(/\)/g, '\\)')

I have edited the question. We need to take into account that there are other parantheses in the string too.
