我正在尝试写一个类似的小无限滚动到这里找到的滚动:http://jsfiddle.net/vojtajina/U7Bz9/
我已经能够显示前5个数据,但是在滚动时,其他项目没有显示。
HTML:
<div id="fixed" directive-when-scrolled="loadMore()">
<ul>
<li ng-repeat="i in items | limitTo: 5">{{ i.Title }}</li>
</ul>
</div>
JS:
var app = angular.module('app', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.items = [
{
"Title":"Home"
},
{
"Title":"Contact"
},
{
"Title":"Help"
},
{
"Title":"About"
},
{
"Title":"Our Offices"
},
{
"Title":"Our Locations"
},
{
"Title":"Meet the Team"
}
,
{
"Title":"Our Mission"
},
{
"Title":"Join Us"
},
{
"Title":"Conferences"
},
{
"Title":"Tables"
},
{
"Title":"Chairs"
}
];
var counter = 0;
$scope.loadMore = function() {
for (var i = 0; i < 5; i++) {
$scope.items.push({id: counter});
counter += 10;
}
};
$scope.loadMore();
});
app.directive("directiveWhenScrolled", function () {
return function(scope, elm, attr) {
var raw = elm[0];
elm.bind('app', function() {
if (raw.scrollTop + raw.offsetHeight >= raw.scrollHeight) {
scope.$apply(attr.whenScrolled);
}
});
};
});

有两个问题。首先,attr.whenScrolled
是什么?它未定义。第二个 - limitTo: 5
。你总是只展示5个元素!
这里有工作代码:http://plnkr.co/edit/VszvMnWCGb662azo4wAv?p=preview
改变了什么?您的指令名为directiveWhenScrolled
,因此请致电:
scope.$apply(attr.directiveWhenScrolled);
而不是
scope.$apply(attr.whenScrolled);
如何处理静态限制。将其更改为变量(记住定义默认值):
<li ng-repeat="i in items | limitTo: limit">{{ i.Title }}</li>
现在您的loadMore
函数应如下所示:
$scope.loadMore = function() {
$scope.limit += 5;
};

我发现了一个很棒的angularjs 'infinite' scroll solution。
您需要做的就是在项目中添加一个in-view directive并做下一件事情:
angular.module('infinitScrollApp', ['angular-inview'])
.controller('infinitScrollController', infinitScrollController);
function infinitScrollController($scope) {
$scope.limit = 10;
$scope.items = Array.from(Array(1000).keys());
$scope.loadMore = function (last, inview) {
if (last && inview) {
$scope.limit += 10;
}
}
}
.infinit-scroll-container {
height: 150px;
overflow-y:scroll
}
