Problem using jQuery calculation with European-formatted numbers

由 萝らか妹 提交于 2020-01-07 03:25:07
问题 I am calculating rows with a total with the jQuery.Calculation plugin but the total is ignoring everything after the decimal symbol. I suspect the fix lies in the regex but I can't figure out where. The following method should set the default correct for European decimals, it works pr row but the sum method for the calculation is ignoring the decimal numbers. The regex below is a fix for the official release but it is still not working correct. $.Calculation.setDefaults({ reNumbers: /(-|-\$)?
