Jquery 验证
Jquery数字验证，支持人民币、美元format； /** * Implementation of toFixed() that treats floats more like decimals * * Fixes binary rounding issues (eg. (0.615).toFixed(2) === '0.61') that present * problems for accounting- and finance-related software. */ function toFixed(value, precision, optionals) { var power = Math.pow(10, precision), output; // Multiply up by precision, round accurately, then divide and use native toFixed(): output = (Math.round(value * power) / power).toFixed(precision); if (optionals) { var optionalsRegExp = new RegExp('0{1,' + optionals + '}$'); output = output.replace(optionalsRegExp, ''); } return output; }
