Have a regular expression issue that I can't seem to quite get.
Requirements: - Value between 0-9999 - Optionally can add either one or two decimals ( eg, 0.01 - 9999.99)
I've got a regex test and it looks to pass but when using it in my SAPUI5 app it doesn't seem to be working.

JS code:
var iQuantity = parseFloat(oArticle._Quantity);
var regexp = new RegExp('^([0-9]{1,4})(\.[0-9]{1,2})?$').test(iQuantity);
console.log(iQuantity);
console.log(regexp);
if (regexp === false) {
return this.setItemToError(oInput, oArticle,
this.getResourceBundle().getText("regExp"));
}
Something like this perhaps:
var re = /^(([0-9]{1,4})(\.[0-9]{1,2})?)$/;
var match = re.exec(subject);
if (match != null) {
result = match[1];
} else {
result = "";
}
/^\d{1,digits_before_decimal}$|(?=^.{1,char_count_with_decimal}$)^\d{0,digits_before_decimal}.\d{0,digits_after_decimal}$/;
In your example it is
/^\d{1,4}$|(?=^.{1,7}$)^\d{0,4}.\d{0,2}$/
