Angularjs 滚动加载更多数据

前端技术 2023/09/07 JavaScript

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);
}
});
}
});

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>

重要的部分是指令(directive)和滚动时要加载数据的部分。
