JS正则表达式校验金额

//任意正整数，正小数（小数位不超过2位）var isNum=/^(([1-9][0-9]*)|(([0]\.\d{1,2}|[1-9][0-9]*\.\d{1,2})))$/;var num = '666.62';if(isNum.test(num)) {return true;}//验证金额（含零），保留两位小数var reg = /(^[1-9]([0-9]+)?(\.[0-9]{1,2})?$)|(^(0){1}$)|(^[0-9]\.[0-9]([0-9])?$)/;if (reg.test(num)) {return true;}//验证含0正整数var reg = /^([1-9]\d*|[0]{1,1})$/;if (reg.test(num)) {return true;}
