(23 answers)
Closed 8 years ago.
I have found this link have a simple and useable funciton to convert number to currency.
www.mredkj.com/javascript/nfbasic.html
but how to turn it back form currency to number...
I already try this :
[http://jsfiddle.net/vb2cb1tm/3/]...
But its failed...
I try to read a formatted string using javascript and make a counting on this valua...
I think something as simple as
function numbers(nStr){
return Number(nStr.replace(/[\$\,]/g,''));
}
might do the trick, though it's hard to tell without seeing your original code.
function cur2num(cur) {
return parseFloat(cur.replace(/,/g,"");
}
if currency signs try /[^0-9]\.\-]/g as first argument to the replace

Javascript string to Guid
(5 answers)
Closed 9 months ago.
I am looking to convert a GUID such as 18d874986a114520bd29466a446a50eb to the format 18d87498-6a11-4520-bd29-466a446a50eb
Is there a function in Javascript for doing this?
I googled a bit and looks like the 8-4-4-4-12 format is called UUID. I however, do not find any to UUID conversion libraries.
Do I need to write my own?
One simple approach uses a regex replacement:
var uuid = "18d874986a114520bd29466a446a50eb";
uuid = uuid.replace(/^([a-f0-9]{8})([a-f0-9]{4})([a-f0-9]{4})([a-f0-9]{4})([a-f0-9]{12})$/i, "$1-$2-$3-$4-$5");
console.log(uuid);

How can I get query string values in JavaScript?

Closed 5 years ago.
I'm gonna to write regex or other expression to get coordinates after '='.
My example:
var cords = https://maps.googleapis.com/maps/api/staticmap?center=50.082961,19.966860&zoom=13&size=300x300&sensor=false&markers=color:orange%7C50.082961,19.966860&client=gme-marktplaats&channel=bt_pl&signature=lPDQWiNQ2_mY8xgoVthZHLLYWac=
I want to get 50.082961,19.966860
I know that I could use slice but I think I could write it better with regex.
Simple base for this example: \=(.[0-9]) What's next?
Try this center\=(\d+\.\d+,\d+\.\d+)&
var val = 'https://maps.googleapis.com/maps/api/staticmap?center=50.082961,19.966860&zoom=13&size=300x300&sensor=false&markers=color:orange%7C50.082961,19.966860&client=gme-marktplaats&channel=bt_pl&signature=lPDQWiNQ2_mY8xgoVthZHLLYWac='.match(/center\=(\d+\.\d+,\d+\.\d+)&/)[1]
console.log(val)
But as other's have commented, you likely shouldn't be using regex for this purpose

Calling member function of number literal

Why do I get an error on this, in Javascript:
10000000.toString();
You can see an example in here:
http://jsbin.com/kagijayecu/1/edit?js,console
It's because the JS parser is expecting more digits after the "." rather than a method name, e.g. 1000000.0, and in fact 1000000.0.toString() will work as expected.
wrap it inside () like this (10000000).toString()
When JS parse meets dot after digit it expects floating-point literal, e.g. 1000000.0

Javascript Thousand Separator / string format [duplicate]

Closed 8 years ago.
I have a number is 1205000000, I want display at 1.205.000.000
number.toString().replace(/(\d{3})/g, "$1.").toString()
but result is 120.500.000.0
I don't want reverse a number.
For the sake of correcting your regular expression (obviously for integer values only):
number.toString().replace(/(\d)(?=(?:\d{3})+$)/g, '$1.');
ยป Detailed Regex Explanation
One way would be to reverse the string before your manipulation and ther reverse it again. Like so:
var number = 1205000000;
function reverse(s) {
return s.split("").reverse().join("");
}
var str = reverse(reverse(number.toString()).replace(/(\d{3})/g, "$1."));
alert(str);
See this working fiddle.
EDIT:
See the comments. Its a bit dirty but for that specific number it will work. The link posted by #Artyom Neustroev as a comment under you question seems a whole lot better than this here.
