Angularjs Template Default Value if Binding Null / Undefined (With Filter)
Turns out all I needed to do was wrap the left-hand side of the expression in soft brackets:
<span class="gallery-date">{{(gallery.date | date:'mediumDate') || "Various"}}</span>
How can I use the binary operator alongside the date filter?
<span class="gallery-date">{{gallery.date | date:'mediumDate' || "Date Empty"}}</span>
you also try:
<span class="gallery-date">{{ gallery.date == 'NULL' ? 'mediumDate' : "gallery.date"}}</span>
Just in case you want to try something else. This is what worked for me:
Based on Ternary Operator which has following structure:
condition ? value-if-true : value-if-false
As result:
{{gallery.date?(gallery.date | date:'mediumDate'):"Various" }}
I made the following filter:
angular.module('app').filter('ifEmpty', function() {
return function(input, defaultValue) {
if (angular.isUndefined(input) || input === null || input === '') {
return defaultValue;
}
return input;
}
});
To be used like this:
<span>{{aPrice | currency | ifEmpty:'N/A'}}</span>
<span>{{aNum | number:3 | ifEmpty:0}}</span>
