I am trying to extract number from title. I have title like this:
**
Apartment London, 230.400€, 450,00m2
**
I want to extract only this price number (230.400€), can anybody help me with this?
So far my code look like this
\d+\.?\d+(.)

You can include the amount symbol as part of your RegEx:
/\d+\.?\d+(.)€/
Or you can try using Positive lookahead:
\d+\.?\d+(.)(?=€)

Auto Reg Ex Phone Number format (xxx) xxx-xxxx [duplicate]

I found a pretty old example but it's almost doing exactly what i need to do:
Auto Dash using Javascript on FOCUS (for a telephone number format)
However instead of the current format xxx-xxx-xxxx i'd like to do (xxx) xxx-xxxx
Can someone give me a hand with the script below with this??
$('.telnumber').keyup(function() {
this.value = this.value
.match(/\d*/g).join('')
.match(/(\d{0,3})(\d{0,3})(\d{0,4})/).slice(1).join('-')
.replace(/-*$/g, '');
console.log("this value", this.value);
});

You could do something like this
var a = this.value.match(/\d*/g).join('')
.match(/(\d{0,3})(\d{0,3})(\d{0,4})/).slice(1);
this.value = ['(',a[0],') ',a[1],'-',a[2]].join('');
It's not very elegant but hey, elegance is for tailors right?
Update
Yea, I got bored and made a one-liner, here:
this.value = '('+this.value
.match(/\d*/g).join('')
.match(/(\d{0,3})(\d{0,3})(\d{0,4})/).slice(1)
.map((a,i)=>(a+[') ','-',''][i])).join('');

The code you'll want to change is .join('-'). That's where you're getting the 'xxx-xxx-xxxx' from.

You need to tokenize those 3 regular expressions and then join them separately.

Hi I am creating validation for a form using javascript.
I am wanting to check the telephone number field using if statements to ensure it contains a 4 digit area code then a space followed by a 7 digit number.
Any help would be appreciated.
Thanks

So you need to validate something like 1234 1234567
function isValidTel(numberToTest){
var pattern =/^\d{4} \d{7}$/
return pattern.test(numberToTest);
}

Validation for xxx-xxx-xxxx or (xxx)xxx-xxxx [duplicate]

Whats the regex for
xxx-xxx-xxxx
or
(xxx)xxx-xxxx
I can create regex for the first one with
/^\d{3}-\d{3}-\d{4}$/
but how to add rule in this so it can also handle the second one?

You can use this: -
/^(?:\(\d{3}\)|\d{3}-)\d{3}-\d{4}$/

I'm no guru but this should do the trick;
/^(\d{3}\-)?(\(\d{3}\))?\d{3}\-\d{4}$/

/^(\(\d{3}\))|(\d{3}-)\d{3}-\d{4}$/
