How to match multiple occurrences of a substring
(3 answers)
Closed 2 years ago.
Let's say I have an input field and want to parse all of the numbers from the submitted string. For example, it could be:
Hi I'm 12 years old.
How do I parse all of the numbers without having a common pattern to work with?
I tried:
x.match(/\d+/)
but it only grabs the 12 and won't go past the next space, which is problematic if the user inputs more numbers with spaces in-between them.
Add the g flag to return all matches in an array:
var matches = x.match(/\d+/g)
However, this may not catch numbers with seperators, like 1,000 or 0.123
You may want to update your regex to:
x.match(/[0-9 , \.]+/g)
var words = sentence.split(" ");
var numbers = words.filter(function(w) {
return w.match(/\d+/);
})

Converting php string to Title Case

I would need a Custom JavaScript for a WordPress form, converting upper cases to lower cases. I found some entries here in the community, but not the one I need.
What should be converted ?
For example I get a form entry 'PETER' and I want that the first digit 'P' stays in upper cases and the rest should be converted to lower cases. From 'PETER' to 'Peter'
Who can give a helping hand, please ? Thanks
You can get the sting first char with str[0], the other parts sliced with -1 argument.
const name = "PETER";
function PETERToPeter(str) {
return str[0].toUpperCase() + str.slice(1).toLowerCase();
}
const nameChanged = PETERToPeter(name);
console.log(nameChanged);

I want to replace the dot in a number in Javascript with regular expression; if country_temp is, for example, 1.234, how can I put the value 1234 in country_temp2?
I have tried the following:
const country_temp2 = country_temp.replace(/[a-zA-Z]*\**\s*\./g, "")
but it's not working.
Edit: the original string is composed by characters, asterisk, a number and a dot
Sorry, but I have written in a very fast way.
Try this:
country_temp.replace(/\./g,'')

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

Comma Separated Numbers Regex
(6 answers)
Closed 6 years ago.
I am trying to generate a regex which would match the following sequence-
+911111111111,+912222222222,+913333333333,+914444444444
It should not allow any other character other than + and numbers
I have tried this->
/^(\+91)\d{10}$/
But it works only for one phone number not for multiple phone numbers
If
^\+\d{11}$
(a + followed by 11 digits) is not sufficient you'll need to be more specific about what you want to allow and not-allow.
Update following comment: the first two digits are "91" so those can be specified, and then ten further digits:
^\+91\d{10}$

I have a string that always contains 8 variable values that are separated with a hypen (-) like in the following example:
5-2-2-2-2-2-2-1
What is the best way to split this into 8 separate values so that I can use each of them in a variable if the values can be either an integer or the value 'n/a' ?
Many thanks for any help with this, Tim.
var str = '5-2-2-2-2-2-2-1';
var parts = str.split('-');
for (var i=0;i<parts.length;i++){
console.log(parts[i]);
}
