Question

I’m trying to match elements with a name that is 'container1$container2$chkChecked', using a regex of '.+\$chkChecked', but I’m not getting the matches I expect when the element name is as described. What am I doing wrong?

Answer 1

my guess, by your use of quotes, is you did something like

re = new RegExp('.+\$chkChecked'); 

which won’t work because js takes advantage of the \ in its string interpretation as an escape so it never makes it into the regex interpreter

instead you want

re = new RegExp('.+\\$chkChecked');
