Question

我有一个html导航代码，如下所示

function Data(string) {
  //1. get some data from server according to month year etc.,
  //2. unactive all the remaining li's and make the current clicked element active by adding "active" class to the element
  $('.filter').removeClass('active');
  $(this).addClass('active');
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="row" style="padding-left:21px;">
  <ul class="nav nav-tabs" style="padding-left:40px;">
    <li class="active filter"><a href="#month" onclick="Data('month')">This Month</a></li>
    <li class="filter"><a href="#year" onclick="Data('year')">Year</a></li>
    <li class="filter"><a href="#last60" onclick="Data('last60')">60 Days</a></li>
    <li class="filter"><a href="#last90" onclick="Data('last90')">90 Days</a></li>
  </ul>
</div>

所以从上面的代码我想要做的是，当用户点击任何选项卡时，所有剩余的选项卡应该是不活动的，并且当前当前元素/选项卡应该是活动的，但上面的代码不是工作，所以任何人都可以让我知道，如何使上述代码工作，无论如何我们可以在用户点击选项卡时发送this（当前）对象，因为我只想使用javascript onclick for this？

Answer 1

使用此html获取点击的元素： -

<div class="row" style="padding-left:21px;">
            <ul class="nav nav-tabs" style="padding-left:40px;">
                <li class="active filter"><a href="#month" onclick="Data('month', this)">This Month</a></li>
                <li class="filter"><a href="#year" onclick="Data('year', this)">Year</a></li>
                <li class="filter"><a href="#last60" onclick="Data('last60', this)">60 Days</a></li>
                <li class="filter"><a href="#last90" onclick="Data('last90', this)">90 Days</a></li>
            </ul> 

        </div>

脚本： -

 function Data(string, el)
            {
                $('.filter').removeClass('active');
                $(el).parent().addClass('active') ;
            }

Answer 2

您可以使用addEventListener将this传递给JavaScript函数。

<强> HTML

<button id="button">Year</button>

<强>的JavaScript

(function () {
    var btn = document.getElementById('button');
    btn.addEventListener('click', function () {
        Date('#year');
    }, false);
})();

 function Data(string)
          {
                $('.filter').removeClass('active');
                $(this).parent().addClass('active') ;
          }

Answer 3

尝试

<script>
function Data(string)
{      
  $('.filter').removeClass('active');
  $(this).parent('.filter').addClass('active') ;
} 
</script>

对于班级选择器，您需要在班级名称之前使用.。您需要为父级添加班级。你是在点击锚标签而不是filter。

<div class="row" style="padding-left:21px;">
    <ul class="nav nav-tabs" style="padding-left:40px;">
        <li class="active filter"><a href="#month" onclick="Data(this)">This Month</a></li>
        <li class="filter"><a href="#year" onclick="Data(this)">Year</a></li>
        <li class="filter"><a href="#last60" onclick="Data(this)">60 Days</a></li>
        <li class="filter"><a href="#last90" onclick="Data(this)">90 Days</a></li>
    </ul>

</div>

<script>
    function Data(element)
    {     
       element.removeClass('active');
       element.addClass('active') ;
    }
</script>

Answer 5

你错过了一个点：

<script>
  function Data(string)
    {
      //1. get some data from server according to month year etc.,
      //2. unactive all the remaining li's and make the current clicked element active by adding "active" class to the element
      $('.filter').removeClass('active');
      $(this).addClass('active') ;
    } 
</script>

Answer 6

您的代码中有两个问题。首先，您需要引用以在单击时捕获元素。尝试在函数中添加另一个参数以引用它。当你试图将它添加到函数中的“a”元素时，活动类最初也适用于li元素。试试这个..

<div class="row" style="padding-left:21px;">
 <ul class="nav nav-tabs" style="padding-left:40px;">
      <li class="active filter"><a href="#month" onclick="Data('month',this)">This Month</a></li>
      <li class="filter"><a href="#year" onclick="Data('year',this)">Year</a></li>
      <li class="filter"><a href="#last60"  onclick="Data('last60',this)">60 Days</a></li>
      <li class="filter"><a href="#last90"  onclick="Data('last90',this)">90 Days</a></li>
    </ul> 

</div>

<script>
  function Data(string,element)
    { 
      //1. get some data from server according to month year etc.,
      //2. unactive all the remaining li's and make the current clicked element active by adding "active" class to the element
      $('.filter').removeClass('active');

      $(element).parent().addClass('active') ;

    } 
</script>
