我正在尝试获取 angular-masonry通过 passy 使用无限滚动指令，但我遇到了一些问题。我在 plnkr here 中做这件事.它在控制台中显示为错误，TypeError: Object [object Object] has no method 'imagesLoaded'。
这是我的html
<!DOCTYPE html>

<script src="angular-masonry.js"></script>
<script src="myApp.js"></script>
</head>
<body ng-app="myApp" ng-controller="DemoController">
<div masonry="">
<img class="repeated-img masonry-brick" ng-repeat="image in images" ng-src="http://placehold.it/225x{{image.height}}/{{image.color.bg}}/{{image.color.text}}&text={{image.num}}" />
</div>
<div scroll-trigger="loadMore()" threshold="100">Trigger element</div>
</body>
</html>
还有我的无限滚动指令和应用模块
var myApp = angular.module('myApp', ['wu.masonry']);
myApp.controller('DemoController', function($scope) {
$scope.images = [
{num: 1, height:400}, {num: 2, height:250},
{num: 3, height:225}, {num: 4, height:200},
{num: 5, height:200}, {num: 6, height:225},
{num: 7, height:300}, {num: 8, height:250},
{num: 9, height:275}, {num: 10, height:350},
{num: 11, height:450}, {num: 12, height:275},
{num: 13, height:225}, {num: 14, height:250},
{num: 15, height:250}, {num: 16, height:225}]
$scope.loadMore = function() {
var last = $scope.images[$scope.images.length - 1].num;
var heights = [200, 225, 250, 275, 300, 350, 400, 450]
var colors = ["859994", "51C0C4", "C3D9C6", "EBE2C7", "F5E6D3"]
var textColor = "ffffff";
for(var i = 1; i <= 8; i++) {
var randColor = colors[Math.floor(Math.random()*colors.length)];
$scope.images.push({num: last + i, height: (heights[Math.floor(Math.random()*heights.length)]), color: {bg: randColor, text: textColor}});
}
};
});
myApp.directive('scrollTrigger', function($window) {
return {
link : function(scope, element, attrs) {
var offset = parseInt(attrs.threshold) || 0;
var e = jQuery(element[0]);
var doc = jQuery(document);
angular.element(document).bind('scroll', function() {
if (doc.scrollTop() + $window.innerHeight + offset > e.offset().top) {
scope.$apply(attrs.scrollTrigger);
}
});
}
};
});
谢谢，抱歉，但我是 Angular 的新手。
最佳答案
你应该在 angular 之前加载 jQuery，我也使用了较新版本的 masonry (3.1.2)，因为它似乎加载的图像依赖于较新的版本:
<script src="//code.jquery.com/jquery-2.1.0.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/masonry/3.1.2/masonry.pkgd.min.js"></script>
<script src="//desandro.github.io/imagesloaded/imagesloaded.pkgd.min.js"></script>
<script src="//code.angularjs.org/1.2.13/angular.js"></script>
来自 angular.element(jqLite) docs :
If jQuery is available, angular.element is an alias for the jQuery function. If jQuery is not available, angular.element delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite."
这是源代码(https://github.com/angular/angular.js/blob/v1.2.13/src/Angular.js#L1257):
function bindJQuery() {
// bind to jQuery if present;
jQuery = window.jQuery;
// reset to jQuery or default to us.
if (jQuery) {
jqLite = jQuery;
extend(jQuery.fn, {
scope: JQLitePrototype.scope,
isolateScope: JQLitePrototype.isolateScope,
controller: JQLitePrototype.controller,
injector: JQLitePrototype.injector,
inheritedData: JQLitePrototype.inheritedData
});
// Method signature:
// jqLitePatchJQueryRemove(name, dispatchThis, filterElems, getterIfNoArguments)
jqLitePatchJQueryRemove('remove', true, true, false);
jqLitePatchJQueryRemove('empty', false, false, false);
jqLitePatchJQueryRemove('html', false, false, true);
} else {
jqLite = JQLite;
}
angular.element = jqLite;
}
关于javascript - 让 angular-masonry 工作它说它没有方法 'imagesLoaded'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21962972/
