高清lead_miltiple_delete（請求）：

success_dict = {} 

if request.is_ajax(): 
    selected_leads=request.POST['lead_list_ids'] 
    selected_leads=json.loads(selected_leads) 
    for i,lead in enumerate(selected_leads): 
     if lead!='': 
      print '**********', lead 

      task_del =Lead.objects.filter(id=lead).delete() 
      success_dict['success_msg'] = "Successfully Deleted lead" 

HttpResponse('success_dict') 

$（'＃ btn_delete_selected'）。點擊（函數（）{

var selected_rows=[]; 

$('#lead_list_table').find('tr').each(function(){ 
    var row=$(this); 
    if (row.find('input[type="checkbox"]').is(':checked')) { 
     selected_rows.push(row.find('span').text()) 
     }; 
    }); 
    // slected_values=stringify 
    var selected_rows = JSON.stringify(selected_rows); 
    $.ajax({ 
     url: "{% url 'lead_miltiple_delete' %}", 
     type: 'POST', 
     data: {'lead_list_ids': selected_rows}, 
     success:function(response) 
     { 
      alert(response) 
     } 
    }) 


}); 

Answer 2

你必須通過ID在TR。 <tr data-id="{{ lead.id }}">

您需要使用id進行GET調用服務器。要做到這一點，你需要對象的id。我認爲在$trows之後你可以得到所有的id。

$trows = $this.closest('table').children('tbody').find('tr.selected'), 

// Written in javascript please convert this to jQuery for you need. 
$trows.forEach(function(element) { 
    // Get Id from data-id 
    const elementId = element.dataset.id 
    fetch("/lead/delete/" + elementId) 
})
