从元素可以变化的数组中删除重复元素

Question

我知道以前有人问过类似的问题，但我尝试了所有答案，但没有任何效果。每次点击buttons 和class ognjen 时，我都会创建我的array。所以它看起来像这样：

<button type="button" name="10208823390691752,1317727711586522" value="All contacts" class="btn btn-default ognjen">All contacts</button>
<button type="button" name="10207252567926988,1294280923934896" value="Men" class="btn btn-default ognjen">Men</button>
<button type="button" name="10208823390691752,10207252567926988" value="Women" class="btn btn-default ognjen">Women</button>
<button type="button" name="1317727711586522,1294280923934896" value="Segment 1" class="btn btn-default ognjen">Segment 1</button>

这就是我设法用所有点击元素的值创建一个数组的方法：

$(document).ready(function() {

        var clickedButtons = new Array();
        var numUsers= new Array();
        $('button.ognjen').click(function() {

            var index = clickedButtons.indexOf(this.value);

            if (index === -1){
                clickedButtons.push(this.value);
                numUsers.push(this.name);//value not found so push it
                }else {
                clickedButtons.splice(index, 1);
                numUsers.splice(this.name);// value found so remove it
            }
            var tryIt=numUsers.join();
            var picker=tryIt.split(', ');
            console.log(picker);
});

所以picker 现在是一个数组，在单击某些按钮后可能如下所示：

["10207252567926988,1294280923934896,10208823390691752,1317727711586522,1294280923934896"]

现在，我想从这个数组中删除所有重复的元素。尝试从这些问题中得到答案：

• How to remove duplicates from array - javascript
• Easiest way to find duplicate values in a JavaScript array
• Remove duplicate elements from array using JavaScript
• Remove Duplicates from JavaScript Array

它们都没有奏效。我认为这可能是由于制作这个piker 数组的动态。请帮忙，我整天都在为这个问题苦苦挣扎。

我认为更简单的方法是存储每个按钮的点击状态，然后每次重新创建数组

$(document).ready(function() {

  var clickedButtons = new Array();
  var numUsers = new Array();
  var $btns = $('button.ognjen').click(function() {
    $(this).toggleClass('selected');

    clickedButtons = new Array();
    $btns.filter('.selected').each(function() {
      var values = this.value.split(',');
      values.forEach(function(value) {
        var index = clickedButtons.indexOf(value);
        if (index === -1) {
          clickedButtons.push(value);
        }
      });
    });

    console.log(clickedButtons)
    snippet.log(clickedButtons.join() || 'NONE');
  });
});
