问题
I have an ng-repeat
that displays a list of dates, and information about purchases on that dates.
HTML:
<div ng-repeat="data in MyData">
<p>
{{ data.purchasedOn.substring(6, data.purchasedOn.length - 2) | date:'dd/MM/yyyy' }}
</p>
<br>
<p>
{{ data.purchaseDescription }}
</p>
</div>
Which displays:
01/02/2013
"Lorem ipsum dolor sit amet, consectetur adipisicing elit"
10/04/2014
"Lorem ipsum dolor sit amet, consectetur adipisicing elit"
02/08/2014
"Lorem ipsum dolor sit amet, consectetur adipisicing elit"
13/06/2014
"Lorem ipsum dolor sit amet, consectetur adipisicing elit"
19/02/2013
"Lorem ipsum dolor sit amet, consectetur adipisicing elit"
How can i only show the {{ data.purchaseDescription }}
when purchasedOn
is within the last 6 months from the current month?
回答1:
Assuming that you want to show purchasedOn but not the description, you could use a function like this one described here to determine a date 6 months prior.
function addMonths(date, months) {
date.setMonth(date.getMonth() + months);
return date;
}
Then define a function to get a boolean show/hide value:
function shouldHide(purchasedOn){
var purchaseDate = Date.parse(purchasedOn);
var sixMonthsAgo = addMonths(new Date(), -6);
var hide = purchaseDate < sixMonthsAgo ? true : false;
return hide;
}
Now you can just use your function in an ng-hide in your <p>
element
<p ng-hide={{shouldHide(data.purchasedOn)}}>
{{ data.purchaseDescription }}
</p>
EDIT If you do just want to hide the entire element, you could make a filter function like this:
$scope.filterOldDates = function(date)
{
if(shouldHide(date)){
return false;
}
return true;
};
You would use it like this:
<div ng-repeat="data in MyData | filterOldDates">
