我正试图在Highcharts的条形图中添加标签.在我的案例中,您可以在此处看到每个栏:

$(function () {
  var chart;
  $(document).ready(function() {
    chart = new Highcharts.Chart({

        chart: {
            renderTo: 'container',
            type: 'column'
        },

        title: {
            text: 'Indicator per Sex'
        },

        xAxis: {
           categories: [
                'Jan',
                'Fev',
                'Mar',
                'Apr',
                'May',
               'Jun',
               'Jul',
               'Aug',
               'Sep',
               'Oct',
               'Nov',
               'Dez'
           ]
        },

        yAxis: {
            allowDecimals: false,
            min: 0,
            title: {
                text: 'Consults'
            }
        },

        tooltip: {
            formatter: function() {
                return '<b>'+ this.x +'</b><br/>'+
                    this.series.name +': '+ this.y +'<br/>'+
                    'Total: '+ this.point.stackTotal;
            }
        },

        plotOptions: {
            column: {

在做某事之前,我需要等待两个承诺才能解决.问题是有时我只能根据客户想要的内容发送一个承诺,我需要依靠来自这个$ q.all的结果.如何动态定义变量？

  var makePurchaseToResolve = [];

    if( CartService.items.draws.length ) {
      var drawOrder = {};
      drawOrder.price = $scope.getTotal();
      drawOrder.paymentMethodId = $scope.payment.paymetMethodId;
      drawOrder.orderItems = CartService.items.draws;
      drawOrder.payFromBalance = false;
      makePurchaseToResolve.push(DrawService.makePurchase(drawOrder));
    }

    if( CartService.items.hunters.length ) {
      var hunterOrder = {};
      hunterOrder.paymentMethodId = $scope.payment.paymetMethodId;
      hunterOrder.orderItems = CartService.items.hunters;
      makePurchaseToResolve.push(HunterService.makePurchase(hunterOrder));      
    }


$q.all(makePurchaseToResolve).then(function( res ) {
     $q.all([HunterService.getPurchase(res[0].data.data),DrawService.getPurchase(res.data.data)]).then(function() {

            //here is the problem, because i dont know if i have the two promises to resolve or only one

            $scope.hunters = res[0].data.data[0];
            $scope.drawOrder = res[1].data.data;          
          })
}

我正在建立一个游戏

而我需要做一些事情,当用户点击鼠标右键,保存它,然后按下左键

我怎样才能检测到这种行为？

我想删除元素,id=decoratives / Interior但它不起作用.

如果由于特殊字符而无法正常工作,那么我该如何更改/空白？

$(".remove").on("click", function(e) {
  e.preventDefault();
  var category = $(this).data("cat");
  $('#' + category.replace(/\s/g, '')).remove();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div id="decoratives/Interior">
  <a class="fancybox-gallery" href="http://wallpapercraze.com/images/wallpapers/nowallpaper-585747.jpeg">
    <img class="animate scale animated" src="http://wallpapercraze.com/images/wallpapers/nowallpaper-585747.jpeg" alt="Image1" style="height:75px">
    <div class="image-hover">
      <i class="icon-zoom-in-2"></i>
    </div>
  </a>
  <br>
  <a class="remove" data-cat="decoratives / Interior">Remove Image</a> 

</div>

如何使用纯javascript,在没有Jquery的情况下,在下面的字符串内容中获取最后一个锚标记的href值.

我想.text()从选中的输入中获取标签。实际上，我的代码检查是否检查了输入，然后从每个<li>具有相同类的对象（不仅是检查的对象）中获取标签。我该如何实现？我认为我应该使用.parent（）或.child（）属性，但我不知道如何使用。

我尝试过alert($('#myId input').parent('label').text());但没有成功。

Codepen https://codepen.io/Qasph/pen/LyNJev?editors=1010

$('#result').click(function() {
  // If an input is checked
  if ($('#myId input').is(':checked')) {
    // Get text from label parent
    console.log($('#myId label').text());
  } else {}
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="myId">
  <ul>
    <!-- First class -->
    <li class="myFirstClass"><label><input type="checkbox" value="3">1 - First class</label></li>
    <li class="myFirstClass"><label><input type="checkbox" value="6">2 - First class</label></li>
    <!-- Second class -->
    <li class="mySecondClass"><label><input type="checkbox" value="3">1bis - Second class</label></li>
    <li class="mySecondClass"><label><input type="checkbox" value="6">2bis - Second class</label></li>
  </ul>
</div>
<button id="result">Result</button>

我想检测浏览器是否支持URL（）构造函数。

我想这样使用它：

const url = new URL(urlString, [baseURLstring])

我找不到合适的方法来检查浏览器是否支持它？

我需要将一些用户生成的字段映射到我正在开发的系统可以识别的内容。

为此，我们希望为用户提供一定的自由度，并为每个领域提供五个左右的选项。

到目前为止，我们有一个开关可以完成这项工作，但现在我们必须扩展开关，而且它会很大。不用说，这不是一种非常动态的方式。还有其他选择吗？

function findHeader(object) {
  var title = object.toString().trim().toLowerCase()
  switch (title) {
    case 'name':
    case 'idea':
    case 'ide':
    case 'ide navn':
    case 'title':
    case 'idea name':
      title = 'name'
      break
    case 'beskrivelse':
    case 'problemet':
    case 'description':
    case 'the problem':
    case 'ide beskrivelse':
      title = 'description'
      break
    case 'ejer':
    case 'owner':
    case 'opfinder':
    case 'ide person':
    case 'idea person':
    case 'person':
      title = 'owner'
      break
    case 'duedate':
    case 'deadline':

这些天我正在做一个项目。我的目标是更改两个正方形相交区域的颜色。我已经编写了检测两个正方形何时相交的代码，但无法弄清楚如何更改相交区域的颜色。请帮助我。

let squares = [];
let dragObject = null; // variable to hold the object being dragged

function setup() {
  createCanvas(600, 520);
  button1 = createButton("Alpha");
  button2 = createButton("Bravo");
  button3 = createButton("Charlie");
  button4 = createButton("Delta");
  button5 = createButton("Echo");
  button6 = createButton("Foxtrot");
  button7 = createButton("Golf");
  button8 = createButton("Hotel");
  button9 = createButton("India");
  button10 = createButton("Juliet");

  button1.mousePressed(doSomething);
}

function draw() {

  background(25, 240, 255);

  // if a square is being dragged, update its position
  if (this.dragObject != null) {
    this.dragObject.position.x = mouseX;
    this.dragObject.position.y = …

我有一个<input type="time">. Chrome 允许用户部分填写输入。例如，用户输入小时但不输入分钟，或者反之亦然。有没有办法使用 JavaScript 来检查该元素是否为空或部分填充？

value只要输入仅部分填充，该属性就是空的。所以那个不行。有没有可以利用的财产？

实际上我对部分输入的值不感兴趣。只是想通过警告没有小时或分钟的时间无效并将被忽略来改善用户体验。
