You can do it with plain JavaScript   alert  123-4-  substr 0  4       outputs  123-    This returns the first four characters of your string  adjust 4 to suit your needs

You can also try this in plain javascript   1234  slice 0 -1    the negative second parameter is an offset from the last character  so you can use -2 to remove last 2 characters etc
