You can use slice! You just have to make sure you know how to use it. Positive #s are relative to the beginning, negative numbers are relative to the end.
I have a string,
12345.00, and I would like it to return
I have looked at
trim, but it looks like it is only trimming whitespace and
slice which I don't see how this would work. Any suggestions?
The easiest method is to use the
slice method of the string, which allows negative positions (corresponding to offsets from the end of the string):
var s = "your string"; var withoutLastFourChars = s.slice(0, -4);
If you needed something more general to remove everything after (and including) the last underscore, you could do the following (so long as
s is guaranteed to contain at least one underscore):
var s = "your_string"; var withoutLastChunk = s.slice(0, s.lastIndexOf("_")); // withoutLastChunk == "your"
You can use the substring function:
var str = "12345.00"; str = str.substring(0, str.length - 1); // "12345.0"
This is the accepted answer, but as per the conversations below, the slice syntax is much clearer:
var str = "12345.00"; str = str.slice(0, -1); // "12345.0"
s = s.substring(0, s.length - 4)
It unconditionally removes the last four characters from string
However, if you want to conditionally remove the last four characters, only if they are exactly
var re = /_bar$/; s.replace(re, "");
This should work:
