How split a string in jquery with multiple strings as separator

Question

i want to split a string in jquery or javascript with multiple separator.
for one string as separator we can have :

var x = \"Name: John Doe\\nAge: 30\         


        

Answer 1

Here's a function based on one of @DenysSéguret's answers:

String.prototype.xSplit = function(separators){
    return this
      .split(new RegExp(separators.join('|'), 'g'))
      .map(function(bar){ return bar.trim() }); // remove trailing spaces
}

Usage:

var foo = "Before date Date: between date & age Age: after age";
foo = foo.xSplit(​​​​​​​​​​​​​​​["Date:", "Age:"]);

Outcome:

foo == ["Before date", "between date & age", "after age"]

Answer 2

You can do

var tokens = x.split(/Age:|Date:/g);

This gives 3 strings :

["Name: John Doe
", " 30
Birth ", " 12/12/1981"]

If you want also to get the separators, use

var tokens = x.split(/(Age:|Date:)/g);

This gives 5 strings :

["Name: John Doe
", "Age:", " 30
Birth ", "Date:", " 12/12/1981"]

If you want to build your regexp dynamically use

var separators = ["Date:", "Age:"];
var tokens = x.split(new RegExp(separators.join('|'), 'g'));​​​​​​​​​​​​​​​​​

or

var separators = ["Date:", "Age:"];
var tokens = x.split(new RegExp('('+separators.join('|')+')', 'g'));
