给《IT资产管理系统》增加显示、隐藏列功能, 自定义显示表格字段

1. 在表格的下方添加一个链接【显示/隐藏列】

<a href="#" οnclick="func11();">【显示/隐藏列】</a>

2. 用javascript写一段函数

<script>

    function func11() {
        //iframe窗
        parent.layer.open({
            type: 2,
            title: false,
            closeBtn: 1, //不显示关闭按钮
            shade: [0],
            area: ['340px', '215px'],
            offset: 'auto', //右下角弹出
            time: 1000, //2秒后自动关闭
            shift: 2,
            content: ['', 'yes'], //iframe的url，no代表不显示滚动条
            end: function(){ //此处用于演示
                parent.layer.open({
                    type: 2,
                    title: '',
                    shadeClose: true,
                    shade: false,
                    maxmin: false, //开启最大化最小化按钮
                    area: ['300px', '450px'],
                    offset: '200px',
                    content: '/deviceman/showhidecolumns',
                    end: function(){
                    location.reload();
                    }
                });
            }
        });
    }




</script>

3. 后端写一个接view.py

def showhidecolumns(request):

    initial_list = ['host_name', 'service_tag','motable__hosttype_list__name','motable','receive_date','user_list__dept_list__bl_list__bl_name','user_list__dept_list__dept_name','user_list', 'pcstatustable', \
                                                            'site_list','asset_code','ownername','user_list__work_category__name']
    if request.method == 'GET':
            includes_list=request.session.get('includes_list',[])
            if len(includes_list) > 0:
                initial_list = includes_list
            columns_list = request.session.get('columns_list_session')
            #print(columns_list)

            obj = showhidecolumnsform(request,initial={'sh':initial_list})

            return render(request, 'showhidecolumns.html' ,{'obj':obj})
    else:
        obj = request.POST.getlist('sh')
        request.session['includes_list']=obj
        #print('obj',obj)
        excludes = request.session.get('columns_list_session')
        excludes_dict = dict(excludes)
        for i in obj:
            #print(str(i))
            del excludes_dict[i]
        #print(tuple(excludes_dict.keys()))
        request.session['excludes_list'] = tuple(excludes_dict.keys())
        return HttpResponse('<br><br> <div style="text-align:center"><h3>设置成功!</h3></div>')
