I have a string
var houseNumber = '13a';
I want to split the addition from the number so I can keep it in a other field.
How can I split this value without losing the number or the addition? At the end I would like to have 2 fields with the following type:
var houseNumber = 13; //Number
var addition = 'a'; //String
There are many questions about this, but I can't find one where both values has to be saved. That's why I created a new question.
Use the following code
var string_a = "jkjkhj89898";
var x = string_a.match(/[^\d]+|\d+/g);
console.log(x)
working fiddle.
Thanks

How do I format plain 10 digit phone no. to us style (xxx)-xxx-xxxx using javascript regular expression.
This should do it: ^(\d{3})(\d{3})(\d{4})$
Here is a working example:
var testNumber = '1234567890';
var regex = /^(\d{3})(\d{3})(\d{4})$/;
var sub = '($1)-$2-$3';
var usNumber = testNumber.replace(regex, sub);

I have a string I am trying to get the last character with jquery. How would I do that?
var stringTemp = "fieldNameWithIndex_1";

Use .split():
