How to Split string with multiple rules in javascript

Question

I have this string for example:

str = \"my name is john#doe oh.yeh\";

the end result I am seeking is this Array:

strArr = [\'my

You have to use a Regular expression, to match all special characters at once. By "special", I assume that you mean "no letters".

var pattern = /([^ a-z]?)[a-z]+/gi;             // Pattern
var str = "my name is john#doe oh.yeh";         // Input string
var strArr = [], match;                         // output array,  temporary var
while ((match = pattern.exec(str)) !== null) {  // <-- For each match
   strArr.push( (match[1]?'&':'') + match[0]);  // <-- Add to array
}
// strArr is now:
// strArr = ['my', 'name', 'is', 'john', '&#doe', 'oh', '&.yeh']

It does not match consecutive special characters. The pattern has to be modified for that. Eg, if you want to include all consecutive characters, use ([^ a-z]+?).

Also, it does nothing include a last special character. If you want to include this one as well, use [a-z]* and remove !== null.
