I have encountered an issue with date validation from the database where some years in the date fields appear to be incorrect (such as 28.02.0302). I need to validate these dates properly, but the functions I found online are not working as expected. How can I make them function correctly? Here are the functions I have attempted to use:
function isValidDate(d) {
if ( Object.prototype.toString.call(d) !== "[object Date]" )
return false;
return !isNaN(d.getTime());
}
function isValidDate11(s) {
// format D(D)/M(M)/(YY)YY
var dateFormat = /^\d{1,4}[\.|\/|-]\d{1,2}[\.|\/|-]\d{1,4}$/;
if (dateFormat.test(s)) {
// remove any leading zeros from date values
s = s.replace(/0*(\d*)/gi,"$1");
var dateArray = s.split(/[\.|\/|-]/);
// correct month value
dateArray[1] = dateArray[1]-1;
// correct year value
if (dateArray[2].length<4) {
// correct year value
dateArray[2] = (parseInt(dateArray[2]) < 50) ? 2000 + parseInt(dateArray[2]) : 1900 + parseInt(dateArray[2]);
}
var testDate = new Date(dateArray[2], dateArray[1], dateArray[0]);
if (testDate.getDate()!=dateArray[0] || testDate.getMonth()!=dateArray[1] || testDate.getFullYear()!=dateArray[2]) {
return false;
} else {
return true;
}
} else {
return false;
}
}
