好吧,我有点难过.
我试图想象来自jQuery背景的角度方式.
问题:如果窗口没有滚动,我只想隐藏一个固定的元素.如果有人向下滚动页面我想隐藏元素.
我已经尝试创建一个自定义指令,但我不能让它工作,因为滚动事件没有触发.我正在考虑一个像下面这样的简单控制器,但它甚至都没有运行.
控制器:
.controller('MyCtrl2', function($scope,appLoading, $location, $anchorScroll, $window ) {
angular.element($window).bind("scroll", function(e) {
console.log('scroll')
console.log(e.pageYOffset)
$scope.visible = false;
})
})
视图
<a ng-click="gotoTop()" class="scrollTop" ng-show="{{visible}}">TOP</a>

任何想法将不胜感激.
我正在构建一个需要物理引擎的站点.与许多SPA应用程序合作后,我感到非常自信.
不幸的是,我在将碰撞检测和墙壁应用于着名的物理模拟时遇到了麻烦.
您可以在此处查看可编辑示例.

我想知道的是有可能在粒子上添加碰撞吗？我试过这个,但看起来碰撞设置不正确.我希望有人成功地做到了.
谢谢!

http://angular-ui.github.io/bootstrap/#/datepicker
目前它被硬编码显示42天或6周.
我想知道如何在ui-bootstrap-0.13.1.js中覆盖(即角度装饰器)这个函数来显示4周.
这是功能:
ctrl._refreshView = function() {
var year = ctrl.activeDate.getFullYear(),
month = ctrl.activeDate.getMonth(),
firstDayOfMonth = new Date(year, month, 1),
difference = ctrl.startingDay - firstDayOfMonth.getDay(),
numDisplayedFromPreviousMonth = (difference > 0) ? 7 - difference : -difference,
firstDate = new Date(firstDayOfMonth);
if (numDisplayedFromPreviousMonth > 0) {
firstDate.setDate(-numDisplayedFromPreviousMonth + 1);
}
// 42 is the number of days on a six-month calendar
var days = getDates(firstDate, 42);
for (var i = 0; i < 42; i++) {
days[i] = angular.extend(ctrl.createDateObject(days[i], …是否可以在 matter.js 中创建一个位于 x/y 坐标中心的重力/力点？
我已经设法用 d3.js 做到了，但想询问 matt.js，因为它能够使用多个 polyshapes。
我有一个ng-repeat正在输出一些<p>.我想截断文本并添加一个更多的按钮,当您单击它时会展开.
这是我到目前为止:
//NG-repeat
<div class="col-xs-4 mbm" ng-repeat="wine in wines">
<p readMore> {{wine.copy|truncate: textLength }}
<a ng-click="changeLength()" class="color3"><strong>More</strong></a>
</p>
</div>
//NG-click
$scope.changeLength = function() {
$scope.textLength = 9999;
}
我有一个自定义指令,能够截断字符串的长度.但是当尝试通过修改文本长度时,ng-click我发现修改了所有项目ng-repeat.
有没有办法改变单个ng-repeat项目？
