Javascript Solutions
Solution 1 - Javascript
As replace() creates/returns a new string rather than modifying the original (tt), you need to set the variable (tt) equal to the new string returned from the replace function.
tt = tt.replace(/,/g, '.')
Solution 2 - Javascript
You can also do it like this:
var tt="88,9827";
tt=tt.replace(",", ".");
alert(tt);
Solution 3 - Javascript
After replacing the character, you need to be asign to the variable.
var tt = "88,9827";
tt = tt.replace(/,/g, '.')
alert(tt)
In the alert box it will shows 88.9827
Solution 4 - Javascript
From the function's definition (http://www.w3schools.com/jsref/jsref_replace.asp):
> The replace() method searches a string for a specified value, or a > regular expression, and returns a new string where the specified > values are replaced. > > This method does not change the original string.
Hence, the line: tt.replace(/,/g, '.') does not change the value of tt; it just returns the new value.
You need to replace this line with: tt = tt.replace(/,/g, '.')
Solution 5 - Javascript
Per the docs, replace returns the new string - it does not modify the string you pass it.
var tt="88,9827";
tt = tt.replace(/,/g, '.');
^^^^
alert(tt);
Solution 6 - Javascript
This will need new var ttfixed
Then this under the tt value slot and replace all pointers down below that are tt to ttfixed
ttfixed = (tt.replace(",", "."));
