下面的例子只是为了简单记录怎么使用angularjs来实现滚动加载数据，具体的还是需要具体看待:
Javascript部分的controller
app.controller('AnalysizerCtrl', ['$scope', '$timeout', '$window',
function ($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('whenScrollEnd', function () {
return function (scope, elm, attr) {
var pageWindow = $(this);
pageWindow.bind('scroll', 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);
}
});
}
});
</div>
下面是HTML部分：
<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></div>
重要的部分是指令(directive)和滚动时要加载数据的部分。
