The following example is just to simply record how to use angularjs to implement scrolling loading of data. The specific details still need to be viewed in detail:

The controller of the Javascript part

app.controller(&#39;AnalysizerCtrl&#39;, [&#39;$scope&#39;, &#39;$timeout&#39;, &#39;$window&#39;,
function ($scope, $timeout, $window) {
$scope.showData = false;
$scope.isLoadingPIG = false;
$scope.isLoadingUJ = false;
$scope.isLoadingBoxSummary = false;
$scope.LoadingData = function (index) {
$scope.showData = true;
var pigHeight = $(".analysisContainer")[1].children[1].scrollHeight;
var ujHeight = $(".analysisContainer")[1].children[2].scrollHeight;
var boxSummaryHeight = $(".analysisContainer")[1].children[3].scrollHeight;
if (index == 0) {
//$scope.reLoadData = true;
pigHeight = 0;
ujHeight = 0;
$scope.gridOptions.data = null;
}
var showSummaryBox = function () {
$scope.isLoadingBoxSummary = false;
}
var showUj = function () {
$scope.isLoadingUJ = false;
//$scope.isLoadingSummaryBox = true;
//$timeout(showSummaryBox, 1000);
}
var showPig = function () {
$scope.isLoadingPIG = false;
//$scope.isLoadingUJ = false;
//$timeout(showUj, 10000);
}
if (pigHeight == 0) {
$scope.isLoadingPIG = true;
$timeout(showPig, 1000);
} else if (ujHeight == 0) {
$scope.isLoadingUJ = true;
$timeout(showUj, 1000);
} else if (boxSummaryHeight == 0) {
$scope.isLoadingBoxSummary = true;
$timeout(showSummaryBox, 1000);
}
};
}]
).directive(&#39;whenScrollEnd&#39;, function () {
return function (scope, elm, attr) {
var pageWindow = $(this);
pageWindow.bind(&#39;scroll&#39;, function (et, ed, pb) {
var winScrollTop = pageWindow.scrollTop();
var winHeight = pageWindow.height();
var maxScrollHeight = $(".analysisContainer")[1].scrollHeight;
if ((winScrollTop + winHeight) > maxScrollHeight) {
scope.$apply(attr.whenScrollEnd);
}
});
}
});

The following is the HTML part ：

<div class="analysisContainer" ng-show="showData" when-scroll-end="LoadingData()">
<div id="b" ng-show="isLoadingPIG" style="width: 100%; text-align: center; z-index: 1">
<h6 class="loading">
<img src="~/Content/Images/loading2.gif" />
Loading Win & Convert data...
</h6>
</div>
<div id="a" ng-show="!isLoadingPIG">
<img src="~/2016-03-16_152323.png" />
</div>
<div ng-show="!isLoadingUJ">
<img src="~/2016-03-16_153347.png" />
</div>
<div ng-show="!isLoadingBoxSummary">
<img src="~/2016-03-16_153404.png" />
</div>
</div>

Copy after login

The important part is the directive and the part to load data when scrolling.
