I'm using AngularJS v1.2.9
.
Inside ng-repeat
, how do i use check the value of object and do action based on condition?
In English, something like:
if `X` is not null, then show `X`. Is it possible?
Here's my ng-repeat
skeleton:
<li ng-repeat="r in results">
<div>{{ r.title }}</div>
<div>{{ r.location }}</div>
<!--
if ( r.date!=="null" ) {
<div>{{ r.date }}</div>
} else {
<div>Date not confirmed yet.</div>
}
-->
</li>
I need to show r.date
if it is not null. If it is null, then i say something else.
Please kindly help. Thanks all.
You can use unique filter while using ng-repeat . If you use track by $index then unique won't work. ok, I used unique and its working now, thanks!
And you should consider using ng-repeat with pagination. You can consider using transclusion inside a custom directive, to achieve the behavior you are looking for without using ng-repeat.
Each ng-repeat creates a child scope with the passed data, and also adds an additional $index variable in that scope. So what you need to do is reach up to the parent scope, and use that $index . Save this answer.
AngularJS ng-repeat Directive The ng-repeat directive repeats a set of HTML, a given number of times. The set of HTML will be repeated once per item in a collection. The collection must be an array or an object. Note: Each instance of the repetition is given its own scope, which consist of the current item.
<li ng-repeat="r in results">
<!-- If r.date contains a value, show it -->
<span ng-if="r.date">{{r.date}}</span>
<!-- If r.date does not contain a value show placeholder text -->
<span ng-if="!r.date">Date not confirmed yet.<span>
</li>

Update
Question wasn't much clear so here is what you wanted just by having ng-bind
directive in place. If the content is bigger then you can switch to the way suggested by @JustOneMoreQuestion below.
<li ng-repeat="r in results" ng-if="r.date">
<div ng-bind="r.date ? r.date : 'Date not confirmed yet.'"></div>
</li>
You could easily do by using ng-if
<li ng-repeat="r in results" ng-if="r.date">
<!--
if ( r.date!=="null" ) {
{{ r.date }}
}
-->
</li>
OR go for a filter which will filter out those will create a collection of element which has date
in it.
<li ng-repeat="r in results| filter: { date: '' }">
<!--
if ( r.date!=="null" ) {
{{ r.date }}
}
-->
</li>
Check this one,
<li ng-repeat="r in results" >
<div data-ng-if="r.date !== 'null'">
Your Date
</div>
<div data-ng-if="r.date == 'null'">
Date not confirmed yet
</div>
</li>
