Based on Dynamic orderBy in AngularJS I try to implement a dynamic sort function with parameters. It's not working properly because the default sort is being called. How can I make it not calling the default sort by name?
I have 2 buttons to call the function and send the parameter.
<button ng-click="dynamicOrder('f9.id')" class="btn">Sort by rating</button>
<button ng-click="dynamicOrder('name')" class="btn">Sort alphabetic</button>
My ng-repeat looks like this:
<li ng-repeat="item in cumulus.items | orderBy: dynamicOrder()"
ng-show="cumulus.items.length > 0" class="block-grid-item">
<p>
<a target="_blank" href="{{ item.image }}">
<img class="img-responsive" src="{{ item.thumb }}">
</a>
</p>
<p style="overflow: hidden;">{{ item.name }}</p>
<p class="text-primary"><input type="hidden" value="{{ item.f9.id }}" /> {{ item.f9.displaystring }}</p>
</li>
and my function for order
$scope.dynamicOrder = function (sortParam) {
if (!sortParam) {
return 'name';
} else {
console.log("sortParam: ", typeof (sortParam), sortParam);
return sortParam;
}
};
The orderBy expression can be a getter function. This function will be called with each item as argument and the return value will be used for sorting.
$scope.getterFn = function(item) {
if ($scope.dynamicOrder == 'f9.id') {
return item.f9.id;
} else if ($scope.dynamicOrder == 'name') {
return item.name;
} else {
return item;
}
};
Usage:
<button ng-click="dynamicOrder = 'f9.id'" class="btn">Sort by rating</button>
<button ng-click="dynamicOrder = 'name'" class="btn">Sort alphabetic</button>
<li ng-repeat="item in cumulus.items | orderBy: getterFn">
<!-- ... -->
</li>
