覆盖split（）逗号分隔符

Question

I am using javascript split() method, but I would like to override the comma delimiter with anything else : eg :

Rather than having this :

var str = "How are you doing today?";
var res = str.split(" ");
//Result : How,are,you,doing,today?

I would like to have this :

var str = "How are you doing today?";
var res = str.split(" ");
//Result : How%are%you%doing%today?

Do you have any idea on how to achieve this ? Thank you !

Split is used to split String over delimiter to Array as example:

var str = "How are you doing today?";
var res = str.split(" ");    // ["How", "are", "you", "doing", "today?"] 

and you can split over anything else like split on comma, what you are trying to achieve is to get string and replace space with % can be done by 2 ways:

First: Split over space and get the array each word alone then join them again over the delimiter you want as in this example is comma:

var str = "How are you doing today?";
var res = str.split(" ").join("%");    // "How%are%you%doing%today?"

Second: Replace each space in the string with comma, and /g g is used to replace all occurrences of the space to not only the first one:

var str = "How are you doing today?";
var res = str.replace(/ /g,"%");;    // "How%are%you%doing%today?"
