显示我的用户数量并将其显示在徽章上。（代码点火器）

Question

这里是新手。我做了一个 ajax 来计算用户数量并将其显示在我的徽章上，但是，每当我单击 1 个按钮（带有 table 的模式）时，它都会显示在所有徽章上。例如。我的第一行模式 table 中有 4 个用户。 #4 计数显示在我所有的徽章上。这很奇怪。我的目标是动态显示徽章中的计数。为了更好地解释，我在下面提供了视频和图片。

这就是我 aim/target 的目的。

Answer 1

正如您使用的那样 .navbar-badge 这将针对所有具有 class 的元素，这就是它更改所有 span 标签的原因。相反，因为您已经获得了 data-id 按钮，您可以使用它来使用 $("span[data-id=" + view_id + "]").text("sometext") 仅针对所需的跨度。

演示代码 :

$(document).ready(function() {
  $(".allTable").on("click", function() {
    var view_id = $(this).data('id')

    /*$.ajax({
//somecodes of ajx ..
      */
    // $("span[data-id="+view_id+"]").text(Object.keys(item).length);
    $("span[data-id=" + view_id + "]").text(10);
    // other codes ..
    /*  }
    });*/
  })
});
