我想getFollowersIds()在Twitter4j中使用粉丝,但我明白了

ConnectionErrorException ...超出速率限制

public static void main(String[] args) {
        try {
            Twitter twitter = TwitterFactory.getSingleton();
            String[] srch = new String[]{"TechCrunch"};
            ResponseList<User> users = twitter.lookupUsers(srch);
            for (User user : users) {

                UserHarvest us = new UserHarvest(6017542);
                us.getFollowersIds();
                try {
                    us.getContributors();
                } catch (ConnectionErrorException ex) {
                    Logger.getLogger(UserHarvest.class.getName()).log(Level.SEVERE, null, ex);
                }
            }
        } catch (TwitterException ex) {
            Logger.getLogger(UserHarvest.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

我在模态窗口中使用Twitter Bootstrap 2.3.2和bootstrap-slider插件.问题是滑块的工具提示的一部分重叠在模态窗口的标题后面并且位置错误.

我试图添加此规则,但它没有帮助.

.slider .tooltip{
    z-index: 1151 !important;
}

我想提供正确的jsfiddle,但我无法找到bootstrap-slider插件cdn.这是jsfiddle,它不起作用,因为缺少bootstrap-slider插件源.

我使用与Tomcat捆绑在一起的Bootstrap 2.3.2和Liferay 6.2.我在Bootstrap 2.3.2中创建了一些具有复杂主体结构的模态窗口,我想在我的门户中使用它们.这里是说,Liferay的使用引导2.3.2 CSS,而不是自引导2.3.2 JavaScript和部件,如模态,工具提示,标签,......都包含在AlloyUI.

我包括Bootstrap 2.3.2 javascript并试图使用我的模态窗口,但如果我想显示模态窗口它不会出现.我想问一下,我怎样才能在Liferay中显示原生引导模态.

我正在尝试在React-Mapbox-GL 中实现自定义缩放行为。如果用户滚动，地图不会缩放，只有网页在滚动。只有当用户“双指缩放”时，地图才能缩放。

我使用scrollZoom: false，它禁用两个操作的缩放（滚动和“双指缩放”）。然后，我添加了react-quick-pinch-zoom库及其onUpdate事件，这有助于我为“pinch-to-zoom”事件添加侦听器。

缩放体验不好，我不知道如何实现与 React-Mapbox-GL 类似的缩放体验。

代码沙盒

import QuickPinchZoom from "react-quick-pinch-zoom";

  maxZoom: 18,
  scrollZoom: false
});

const MapContainer = () => {
  const [mapZoom, setMapZoom] = useState(8);

  const onUpdate = useCallback(
    ({ scale }) => {

我有一个元组数组,其中元组的第一个元素是字符串,第二个元素是int.每个元组都有数组结构:

var array = [["ele1",1], ["ele2",1], ["ele3",1], ["ele4",1]];

如何在javascript中轻松检查字符串是否是元组数组中元组的元素？

if array.contains(tuple with first element "ele2")

没有for循环(检查数组的每个元素)是否可以这样做？

我试图在jQuery中删除已选中的复选框,但是当我想获得复选框的状态时,我会收到错误消息.

<label class="checkbox"><input value="4" type="checkbox">Message 4</label>

<label class="checkbox"><input value="7" type="checkbox">Message 7</label>
<label class="checkbox"><input value="8" type="checkbox">Message 8</label>

</div> 


 <button class="btn" type="button" id="deleteAcc">Delete</button>

我的jQuery代码是:

$("#deleteAcc").on("click",function(){      
    $(".control-group label.checkbox").each(function(){
        if (this.children(":first").is(':checked')) {
            this.remove();
        }
    });
