[英]Angularjs ng-repeat passed index not defined
我試圖在 ng-repeat 中打開和關閉按鈕,地圖上的視圖有效,但是當它更改為刪除標記時,它在控制台日志中向我傳遞錯誤“ReferenceError:passedIndex 未定義”。 有什么辦法可以解決嗎?
HTML:
<li class="displaySubCategory" ng-repeat="communityTheme in community | startFrom:currentPage*pageSize | limitTo:pageSize">
<div class="categoryImg">
<img src="img/csvIcon.png" />
<img src="img/shpIcon.png" />
</div>
<div class="categoryDesc">
<p>{{communityTheme.THEMENAME}}</p>
<a href="" ng-hide="communityTheme.visibility" ng-click="getMapData(communityTheme.QUERYNAME, $index)">View on Map</a>
<a href="" ng-show="communityTheme.visibility" ng-click="removeMarker(communityTheme.QUERYNAME, $index)">Remove Marker</a>
</div>
</li>
JS:
$scope.getMapData = function (msg, passedIndex) {
map.addLayer(cities);
$scope.Lng.length = 0;
$scope.Lat.length = 0;
$scope.dataLatLng.length = 0;
queryNameUrl = 'https://developers.onemap.sg/publicapi/themeapi/retrieveTheme?queryName=' + msg +
'&token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOjMsInVzZXJfaWQiOjMsImVtYWlsIjoicHVibGljQXBpUm9sZUBzbGEuZ292LnNnIiwiZm9yZXZlciI6ZmFsc2UsImlzcyI6Imh0dHA6XC9cL29tMi5kZmUub25lbWFwLnNnXC9hcGlcL3YyXC91c2VyXC9zZXNzaW9uIiwiaWF0IjoxNTQwOTI5OTE2LCJleHAiOjE1NDEzNjE5MTYsIm5iZiI6MTU0MDkyOTkxNiwianRpIjoiYjVkNmZkNGJhOWJiNGJiM2FkNWQzN2ZhNTAzMGIxYWEifQ.YQdfV43wrg8dX-He7-mwIL2Qhjsexq0tgNu5RotAdu4';
$http.get(queryNameUrl).then(function(response) {
$scope.apiResult = response.data.SrchResults;
$scope.apiResult.splice(0,1);
console.log($scope.apiResult)
for (var i= 0; i < $scope.apiResult.length; i++) {
if ($scope.apiResult[i].Type == "Point"){
$scope.apiResult[i].visibility = true;
console.log($scope.apiResult)
$scope.dataLatLng.push($scope.apiResult[i].LatLng)
$scope.Lat.push($scope.dataLatLng[i].split(',')[0]);
$scope.Lng.push($scope.dataLatLng[i].split(',')[1]);
L.marker([$scope.Lat[i], $scope.Lng[i]], {icon: greenIcon}).bindPopup($scope.apiResult[i].DESCRIPTION).addTo(cities);
}
// else if ($scope.apiResult[i].Type == "Polygon"){
// $scope.PolyLine.push($scope.apiResult[i].LatLng)
// console.log($scope.PolyLine)
// // for (var i = 0; i < $scope.PolyLine.length; i++) {
// // $scope.polyLineCord.push($scope.PolyLine[i])
// // // console.log($scope.polyLineCord)
// // }
// }
}
})
if($scope.community[passedIndex].visibility)
{
$scope.community[passedIndex].visibility = false;
}
else{
$scope.community[passedIndex].visibility = true;
}
}
刪除標記:
$scope.removeMarker = function ($index) {
if($scope.community[passedIndex].visibility)
{
$scope.community[passedIndex].visibility =false;
cities.clearLayers();
}
else {
$scope.community[passedIndex].visibility = true;
}
}
我在這里先向您的幫助表示感謝 !
您需要通過 $index 使用 track
<li class="displaySubCategory" ng-repeat="communityTheme in community | startFrom:currentPage*pageSize | limitTo:pageSize track by $index">
它應該是passedIndex
代替$index
在removeMarker功能
$scope.removeMarker = function (passedIndex) {
