Question

I’ve seen some posts about JSLint “bad escapement” warnings, but I just wanted to see if I’m doing this Regex correctly. (Note – I’m dabbler programmer).

I have a function (below) that attempts to parse out a variable from it’s name in a long message. The regex is working well, but should I change something in response to the JSLint warning?

A very simplified version of msg could look like this essentially:

VariableName1 = Value1
VariableName2 = Value2
VariableName3 = Value3

The actual msg has different unstructured data above and below. I had to use a strange Regex since even though a more simple one worked on all the testing websites, it didn’t work within the server application we are using, so this is the only way I could get it to work. The regular expression incorporates a variable.

Here is the parsing function I’m using:

    function parseValue(msg, strValueName) {
        var myRegexp = new RegExp(strValueName + ' = ([A-Z3][a-zA-Z\. 3]+)[\\n\\r]+', 'gm');
        log('parseValue', 'myRegexp = ' + myRegexp.toString());
        var match = myRegexp.exec(msg);
        log('parseValue', 'returning match = ' + match[1] );
        return match[1];
    }

There is probably something much simpler that a ‘real’ programmer can come up with pretty easily. Any help would be appreciated.

THanks.

Answer 1

The problem that JSLint didn’t like was the ‘.’ character in the character class as pointed out by ‘Explosion Pills’.

When I removed the ‘.’ all was good.

Thanks.
