问题描述
这里是新手。我做了一个 ajax 来计算用户数并将其显示在我的徽章上，但是，每当我单击 1 个按钮（带表格的模态）时，它都会显示在所有徽章上。例如。我的第一行模态表中有 4 个用户。 #4 计数显示在我的所有徽章上。这是很奇怪的事情。我的目标是在我的徽章中动态显示计数。为了更好地解释，我在下面提供了视频和图片。
这就是我的目标。

型号：
public function view($userID = 0){
$this->db->select("*");
$this->db->from("users");
$this->db->where( "uuid=".$userID);
$query = $this->db->get();
return $result = $query->result();
}
控制器：
public function view()
{
if ($this->input->is_ajax_request()) {
$view_id = $this->input->post('view_id');
if ($post = $this->networks->view($view_id)) {
$data = array('responce' => 'success','post' => $post);
} else {
$data = array('responce' => 'error','message' => 'Failed to fetch record');
}
echo json_encode($data);
} else {
echo "No direct script access allowed";
}
}
脚本：
<script>
$(document).ready(function(){
$(".allTable").on("click",function(){
var view_id = $(this).data('id')
$.ajax({
url: "<?=site_url('network/view')?>",type: "post",dataType: "json",data: {
view_id: view_id
},success: function(data){
var tbody ="";
var item =data.post;
for(var key in item) {
tbody +="<tr>";
tbody += "<td>"+item[key].userID+"</td>";
tbody += "<td>"+item[key].uuid+"</td>";
tbody += "<td>"+item[key].firstname+" "+item[key].lastname+"</td>";
tbody += "<td>"+item[key].email+"</td>";
tbody += "<td>"+item[key].mobile+"</td>";
tbody += "<td>"+item[key].username+"</td>";
tbody +="</tr>"
}
$(".navbar-badge").text(Object.keys(item).length);
$(".tbody").html(tbody);
$('#editModal').modal('show');
}
});
})
});
</script>
解决方法
当您使用 .navbar-badge 时，这将针对具有该类的所有元素，这就是它更改所有跨度标签的原因。相反，由于您已经获得了 data-id 个按钮，因此您可以使用它来使用 $("span[data-id=" + view_id + "]").text("sometext") 仅定位所需的跨度。
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 ..
/* }
});*/
})
