Certain data types in the grid are not automatically formatted in the way that you’d prefer. In this post, I’ll show how to format date and currency columns in a grid using features built into Dojo.

Gridx Series

Gridx in XPages — Entire Series

Formatting Dates

By default, a rest service providing a Notes Date/Time will provide it in a much longer format than you probably want to see in the grid.

Gridx 18 A

To format it, you can use a decorator function (described previously in this post).

Include the dojo locale module in the require statement: dojo/date/locale

Then add a decorator function to format the date. (Make sure the column dataType is set to date.)

decorator: function(value)
{
  try {
    if (value) {
      // NotesDateTime comes out in this format: 2014-10-21T14:47:38Z
      var parsedDate = value.substring(0, 10);
      
      // Create and format the date 
      var dt = new Date(parsedDate);
      var dateString = locale.format(dt,
        {
          selector: "date",
          datePattern: "dd-MMM-yyyy"
        }); 
      
      return dateString;
    }
  } catch (e) {
    console.error('error decorating date: ' + e.toString());
  }
}

Line 6 parses out the first 10 characters from the date string

Line 9 creates a date object from the parsed string.

Lines 10-14 use the dojo locale formatting functionality to format the date to the desired pattern.

Gridx 18 B

Now the date column is formatted in a way that’s much easier to read.

Formatting Currencies

By default a numeric column will display as a plain number.

Gridx 18 C

Similar to the previous example, we can use a dojo module to format the data. In this case, we’ll add dojo/currency to the require statement.

Here’s a decorator function that will format the data. (Make sure the column dataType is set to number.)

decorator: function(value) { 
  if (value) { 
    var formattedCurrency = currency.format(value, {currency: "USD"});
    return formattedCurrency;   
  } 
}

Line 3 is the core of this logic. It uses the dojo currency module to format the data as a currency. The currency attribute defines the currency to use. (Other examples include “EUR”, “GBP”, etc)

Gridx 18 D

Here’s the same data with the currency set to EUR:

Gridx 18 E

Date and currency conversions are a great example of why it is extremely handy to have a JavaScript framework like Dojo available.
