javascript - 使用 ng-click 或 jquery 检测平板电脑上的长按

Question

嗨，我有关注 div：

angular.module("myApp", ['ngTouch']).controller("myController", function($scope) {
  $scope.longClick = function() {
    console.log('I was clicked long');
  }
});

.longClick {
  width: 200px;
  height: 20px;
  line-height: 20px;
  color: white;
  font-family: Arial;
  background-color: grey;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular-touch.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>


<div ng-app="myApp" ng-controller="myController" class="longClick" ng-click="longClick()">Click me long...</div>

我想在平板电脑上检测到，当长按单击/触摸 div 并在控制台中打印文本时。我为这些问题找到了一些答案，但我尝试的一切都没有奏效。有任何想法吗？谢谢。

我给你写了这段代码，它应该可以解决问题。我基本上是在计算 mousedown 和 mouseup 的时间并比较它们

var start;
$(window).mousedown(function(e) {
  start = new Date().getTime();
  
}).mouseup(function(e) {
  var end = new Date().getTime();
  var timeDiff = (end-start)/1000; 
  $('p').text(timeDiff + " seconds");
  
});

<div>
  Click the result area
</div>
