I give up.

How do I replace parenthesis in a string in JavaScript?

In other words, if I have a string that contains a ( or a ), how do I use the JavaScript replace method to replace them with something else?

I tried the code you're supposed to use;

Code:

str.replace(/(/, "Replacement");

But it just fails.

So apparently I have to escape that character since I assume the ( and ) are reserved for something. So how the heck do I escape it and replace a ( or )?

confused

Looks like you're just missing the ' ' or " ".

Code:

str.replace('(', '[');

But that it were that simple.

Alas, that does not work. In fact, that's how I thought it was supposed to be, but no, instead of quotes in the first part, you need to use /'s. As every tutorial on the internets says. But none say how to escape a special reserved character like a ( or ). IT SHOULD NOT BE THIS DIFFICULT! sad

Using quotes however does not cause it to fail. But it still does not replace a thing.

Maybe I'm doing it wrong, maybe not. I can't get any replacements working. I'm in Bowtie FYI, but that shouldn't matter as a Bowtie theme is a Webkit. Same as a Dashboard Widget. Can you not replace in Dashboard either?

Code:

str.replace(/\(/g, '[');

That replaces based on a regular expression. The slashes (/) denote the expression. The letter 'g' after the regex indicates that the search should be global (otherwise it will just replace the first match). You have to escape regex characters (parentheses, brackets, pipes, periods, asterisk, etc.) by placing a backwards slash before them, the same way you would escape quotes in a string.

Code:

str.replace('(', '[');

This should also work. Remember, replace() does not modify the string. Be sure you're assigning the output to something, e.g.:

Code:

str = str.replace(/\(/g, '[');
