Specifying the 'No Records' Message Using JavaScript

JavaScript can be used to dynamically generate the message shown. To specify that the message to display is calculated using JavaScript, the message must be prefixed with javascript: directive.

For example, assume a local function called norecordsmessage was defined in the List Builder's Javascript tab.

You would set the No Records HTML to:

javascript:this.norecordsmessage()

The Javascript tab can be turn on in the List Builder to define functions at This object level. Functions defined on the List's Javascript tab will be stored with the List.

You can also include a5-item attributes in the message text. For example, assume you wanted to display a message if the user tapped on the no records message. Assume also that the message was to be returned by a local function called norecordsmessage(). Here is how this could be done:

First, define an item in the List Builder's Items tab (by turning on the optional Template Items tab (check the box at the bottom of the List Builder window.) For example, you could define an item called 'norecords' that displayed a message when clicked.

Then define the norecordsmessage function as follows:

var norecordsinlist = function () {
    return '<span a5-item="norecords">List has no records</span>';
};

Displaying a Custom Message in the List if the List has No Records

A common requirement in a List is to show a custom message if the List has no records.

The List control has built-in properties to make this easy. You can also automatically center the message horizontally and vertically in the List.
