Formatting the phone number
(3 answers)
Closed 6 years ago.
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);
alert(usNumber);

Javascript and regex: split string and keep the separator

Splitting a string into chunks by numeric or alpha character with JavaScript

Closed 6 years ago.
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

Javascript RegEx Not Working [duplicate]

Closed 6 years ago.
The below code is to validate any input of decimal type with a precision of 2.
function check() {
var str = $('#txttest').val();
var patt = new RegExp("^[0-9]+(\.[0-9]{1,2})?$");
var res = patt.test(str);
alert(res);
}
Valid examples:
12
12.00
12.00a
12a
a12
1a2.00
Failed Case:
In some cases, the function is returning wrong values, like 1a2.
Now, please suggest.
Why don't you use JavaScript's toFixed() method?

I am trying to add a number to an array .
code:

You need to parse the string to an integer before you add to it:
var dt = "12/02/2012";
var mm = de.split("/");
var year = parseInt(mm[2])+1;
