Data come from db , and this html element is a ng-repeat
{{count}}
My Question
How can i show if else condition that,
If count is null (nothing count value) I would show 0 (count value should be zero) , else show original count value
I hope there are solution like {{count if '' else ''}}
You could have have logic in your view with {{count || 0}} or {{ count ? count : 0 }} but this makes maintainability more difficult and duplicates logic.
A better option would be to create a custom filter. This will allow you to define you condition in a single place and makes it re-usable in many directives but also testable.
.filter('isEmpty', function() {
return function (data) {
return (data === null || data === undefined) ? 0 : data;
}
});
And you would use it like
{{item | isEmpty}}

EDIT: Here's the docs for filter that will explain what its doing and also how to pass optional extra parameters into your filters and other cool stuff. https://docs.angularjs.org/guide/filter
How about {{ count ? count : 0 }}
{{count || 0}}
