Remove first character from a string if it is a comma
I need to setup a function in javascript to remove the first character of a string but only if it is a comma ,. I've found the substr function but this will remove anything regardless of what it is.
My current code is
text.value = newvalue.substr(1);
Solution 1:
text.value = newvalue.replace(/^,/, '');
Edit: Tested and true. This is just one way to do it, though.
Solution 2:
s = (s.length && s[0] == ',') ? s.slice(1) : s;
Or with a regex:
s = s.replace(/^,/, '');
Solution 3:
var result = (myString[0] == ',') ? myString.substr(1) : myString;
