Check if string is enclosed in single quotes Javascript

// 'Apple' : valid
// 'Apple : Invalid
// Apple : Invalid

if(str.indexOf('\'') > -1 && str.indexOf('"') > -1){
   // do something
}

This will detect if the string contains single and double quotes.

How to check if string starts and ends with a single quote. (Regexp)?

if((name[0] == "'" && name[name.length - 1] == "'")||(name[0] == '"' && name[name.length - 1] == '"')){
    ///
}

I'd suggest this... It's a total plagiarism of Daniel Robinson's answer, just more complete.

No need for regex, you can use the charAt function:

if (str.charAt(0) == "'" && str.charAt(str.length-1) == "'") {

}
