ISNAN in javascript

isNaN(value) function
Well, isNan function determines whther a value is number or not.. if it is not a number, it returs true else it returns false...

eg: ISNAN("Hello") returns true
ISNAN(123) returns false
And in certain cases, javascript returns NAN in your textbox even though its a number,if you are pressing tab key.. if that is the case inorder to avoid it..just assign the next textbox value to 0 where it appears as NAN.
i.e. document.getelementbyid("idname").value =0;
This will do the trick...

Step1:
Declare an Array to store the datevalues from a string
Step2:
Assign it to the string declarations and append the string with "/"
And reuse the date anywhere in your file according to your need.
Dim sArr()
sArr = stringdate.Split("/")
Dim dd As String = sArr(0).ToString
Dim mm As String = sArr(1).ToString()
Dim yyyy As String = sArr(2).ToString().Substring(0, 4)
Dim sDate As String = mm + "/" + dd + "/" + yyyy
This code snippet is basically useful in situations where UK dateformat is to be used, other than US culture.And We can call this function whereever needed, just for display purpose or conversion purpose.
