Within my controller, I implemented code to convert the rank into a Float data type.
details.rank = '';
$scope.order = function (predicate) {
$scope.reverse = ($scope.predicate === predicate) ? !$scope.reverse : false;
if (predicate == 'rank') {
for (var i = 0; i < data.countries[$scope.index].cities.length; i++) {
details.rank = parseFloat(data.countries[$scope.index].cities[i].rank);
}
$scope.predicate = predicate;
} else $scope.predicate = predicate;
};
However, an error is arising stating that ReferenceError: details is not defined
The json structure in use is as follows:
{
"countries": [{
"country": "India",
"cities": [{
"name": "Bangalore",
"rank": "40"
}, {
"name": "Kolkata",
"rank": "54"
}, {
"name": "Mumbai",
"rank": "32"
}, {
"name": "Chennai",
"rank": "42"
}]
}, {
"country": "China",
"cities": [{
"name": "Guangzhou",
"rank": "111"
}, {
"name": "Beijing",
"rank": "90"
}, {
"name": "Fuzhou",
"rank": "21"
}, {
"name": "Baotou",
"rank": "23"
}]
}]
}
In the html file, there should be functionality where clicking on the table header allows sorting of the table in both ascending and descending order, which currently seems challenging to implement.
<th>
<a href="" ng-click="order('rank')">RANK</a>
<span ng-show="predicate === 'rank'" ng-class="{reverse:reverse}"> </span>
</th>
<ul ng-repeat="city in countryType">
<li ng-repeat="details in city.data.cities | orderBy:predicate:reverse">
<div class="text" id="t1"> {{details.name}} </div>
<div class="text" id="t2"> {{details.rank}}</div>
<div class="text" id="t3"> {{details.population}} </div>
<div class="text" id="t4"> {{details.language}}</div>
</li>
</ul>
