I have a string that is passed by parameter and I have to replace all occurrences of it in another string, ex:
function r(text, oldChar, newChar)
{
return text.replace(oldChar, newChar); // , "g")
}
The characters passed could be any character, including ^, |, $, [, ], (, )...
Is there a method to replace, for example, all ^ from the string I ^like^ potatoes with $?
function r(t, o, n) {
return t.split(o).join(n);
}
If you simply pass '^' to the JavaScript replace function it should be treated as a string and not as a regular expression. However, using this method, it will only replace the first character. A simple solution would be:
function r(text, oldChar, newChar)
{
var replacedText = text;
while(text.indexOf(oldChar) > -1)
{
replacedText = replacedText.replace(oldChar, newChar);
}
return replacedText;
}
Use a RegExp object instead of a simple string:
text.replace(new RegExp(oldChar, 'g'), newChar);
var text = "^xxx^"; text.replace(new RegExp("^", 'g'), "$");
new RegExp("\\"+oldChar,"g")
^ with two backslashes to make it work: var text = "^xxx^"; text.replace(new RegExp("\\^", 'g'), "$");/\z/ and treat it the same as /z/, there are a few broken cases such as /\x/ being treated as an empty hexadecimal character instead of just an /x/.
String.prototype.replaceonly replaces the first occurrence of strings; you need to use a regular expression with theglobal flag if you want global replacement.
