Body
See below. The main function is isDate to which you can pass day, month and year. These are javascript functions, so it alerts a relevant message and returns false. The daysInFebruary will calculate the number of days for feb for the year passed. The DaysArray keeps an array of the number of days for each month. <pre><code>var minYear=1900; var maxYear=2100; function daysInFebruary (year){ // February has 29 days in any year evenly divisible by four, // EXCEPT for centurial years which are not also divisible by 400. return (((year % 4 == 0) && ( (!(year % 100 == 0)) || (year % 400 == 0))) ? 29 : 28 ); } function DaysArray(n) { for (var i = 1; i <= n; i++) { this[i] = 31 if (i==4 || i==6 || i==9 || i==11) {this[i] = 30} if (i==2) {this[i] = 29} } return this } function isDate(strDay,strMonth,strYear ){ var daysInMonth = DaysArray(12) if (strDay.charAt(0)=="0" && strDay.length>1) strDay=strDay.substring(1) if (strMonth.charAt(0)=="0" && strMonth.length>1) strMonth=strMonth.substring(1) for (var i = 1; i <= 3; i++) { if (strYr.charAt(0)=="0" && strYr.length>1) strYr=strYr.substring(1) } month=parseInt(strMonth) day=parseInt(strDay) year=parseInt(strYr) if (strMonth.length<1 || month<1 || month>12){ alert("Please enter a valid month") return false } if (strDay.length<1 || day<1 || day>31 || (month==2 && day>daysInFebruary(year)) || day > daysInMonth[month]){ alert("Please enter a valid day") return false } if (strYear.length != 4 || year==0 || year<minYear || year>maxYear){ alert("Please enter a valid 4 digit year between "+minYear+" and "+maxYear) return false } return true } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
