bootstrap--如何做一个doublebox双向选择器

1、首先什么是双向选择器，上图

 

 

 

类似这样的一个可以穿梭相互选择的选择器，实现方法：html+jquery+django

django-models.py

# 用户组使用了Django自带的group表
from django.contrib.auth.models import User,Group

# Group VS View_Cate 多对多关系
class View_Cate(models.Model):
    name = models.CharField(unique=True,default=None,max_length=50,verbose_name=\'视图名称\')
    user_group = models.ManyToManyField(Group,blank=True,null=True)

    class Meta:
        db_table = \'opsmanage_view_cate\'
        verbose_name_plural = \'视图表\'
        default_permissions = ()

html

<div class="x_content">
<table class="table" id="appListTable">
  <thead>
    <tr>
      <th>ID</th>
      <th>视图名称</th>
      <th class="text-center">操作</th>
    </tr>
  </thead>
  <tbody>
  </tbody>
</table>

</div>

jquery

var language =  {
        "sProcessing" : "处理中...",
        "sLengthMenu" : "显示 _MENU_ 项结果",
        "sZeroRecords" : "没有匹配结果",
        "sInfo" : "显示第 _START_ 至 _END_ 项结果，共 _TOTAL_ 项",
        "sInfoEmpty" : "显示第 0 至 0 项结果，共 0 项",
        "sInfoFiltered" : "(由 _MAX_ 项结果过滤)",
        "sInfoPostFix" : "",
        "sSearch" : "搜索: ",
        "sUrl" : "",
        "sEmptyTable" : "表中数据为空",
        "sLoadingRecords" : "载入中...",
        "sInfoThousands" : ",",
        "oPaginate" : {
            "sFirst" : "首页",
            "sPrevious" : "上页",
            "sNext" : "下页",
            "sLast" : "末页"
        },
        "oAria" : {
            "sSortAscending" : ": 以升序排列此列",
            "sSortDescending" : ": 以降序排列此列"
        }
    }
function InitDataTable(tableId,url,buttons,columns,columnDefs){
      var data = requests(\'get\',url)
      oOverviewTable =$(\'#\'+tableId).dataTable(
              {
                    "dom": "Bfrtip",
                    "buttons":buttons,
                    "bScrollCollapse": false,
                    "bRetrieve": true,
                    "destroy": true,
                    "data":    data,
                    "columns": columns,
                    "columnDefs" :columnDefs,
                    "language" : language,
                    "order": [[ 0, "ase" ]],
                    "autoWidth": false
                });
    }

$(document).ready(function()
{
    makeAppsManageTableList()
})
function makeAppsManageTableList(){
    var columns = [
                   {"data": "id"},
                   {"data": "name"}
                   ]
   var columnDefs = [
                        {
                           targets: [2],
                           render: function(data, type, row, meta) {
                               return \'<div class="btn-view  btn-view-xs">\' +
                                       \'<button type="button" name="btn-view-edit" value="\'+ row.id +\'" class="btn btn-default"><span class="fa fa-edit" aria-hidden="true"></span>\' +

                                       \'</div>\';
                           },
                           "className": "text-center",
                        },
                      ]
    var buttons = [{
        text: \'<span class="fa fa-plus"></span>\',
        className: "btn-xs",
        action: function ( e, dt, node, config ) {
            addViews()
        }
    }]
    InitDataTable(\'appListTable\',\'/api/queryView/\',buttons,columns,columnDefs);
}

 

 

 

 

 

jquery

$("#viewGroupSubmit").on(\'click\', function() {
   var vIds = $(this).val();
   var vServer = $(\'[name="user-group-doublebox"]\').val()
   if (vServer){

         typeAnimated: true,
         content: "没有选择任何用户组~",
         type: \'red\'
      });
   }

});

jquery

function GetViewOrGroups(url,uid){
    var aList = []
    var sList = []
    var url = url + uid +\'/?type=get_user_group\'
    response = requests(\'get\',url)
    if(response["code"]=="200"){
        for (var i=0; i <response["data"].length; i++){
            if (response["data"][i]["apps_name"]){
                var name = response["data"][i]["apps_name"]+ \' - \' + response["data"][i]["name"]
            }else{
                var name = response["data"][i]["name"]
            }
            if(response["data"][i]["status"]==1){
                sList.push({"id":response["data"][i]["id"],"name":name})
            }
            else{
                aList.push({"id":response["data"][i]["id"],"name":name})
            }
        }

    }
    return {"group":sList,"all":aList}
}

django-views.py

        if request.GET.get(\'type\') == \'get_user_group\':
            # todo 视图与角色组关联关系
            cates = App_Cate.objects.filter(id=id).first()
            selected_group = [group for group in cates.user_group.all()]
            groupList = []
            for group in Group.objects.all():
                groupDict = {}
                groupDict[\'id\'] = group.id
                groupDict[\'name\'] = group.name
                if group in selected_group:
                    groupDict[\'status\'] = 1

                else:
                    groupDict[\'status\'] = 0
                groupList.append(groupDict)
            return JsonResponse({\'code\':200,\'data\':groupList})

以上即可拿到数据渲染双向选择器，效果如图一

jquery

$("#viewGroupSubmit").on(\'click\', function() {
    var vIds = $(this).val();
    var vServer = $(\'[name="user-group-doublebox"]\').val()
    if (vServer){
        $.ajax({
            type: "POST",
            url:"/api/cate/info/"+vIds+\'/\',
            data:{
                "type":"modf_view_group",
                "id": vIds,
                "groups":vServer
            },
            error: function(response) {
                new PNotify({
                    title: \'Ops Failed!\',
                    text: response.responseText,
                    type: \'error\',
                    styling: \'bootstrap3\'
                });
            },
            success: function(response) {
                if (response["code"] == 200){
                    new PNotify({
                        title: \'Success!\',
                        text: \'修改成功\',
                        type: \'success\',
                        styling: \'bootstrap3\'
                    });
                }else{
                    new PNotify({
                        title: \'Ops Failed!\',
                        text: response["msg"],
                        type: \'error\',
                        styling: \'bootstrap3\'
                    });
                }
            }
        });
    }else{
        $.confirm({
            title: \'<strong>警告</strong>\',
            typeAnimated: true,
            content: "没有选择任何用户组~",
            type: \'red\'
        });
    }

});

django-views.py

        if data.get(\'type\') == \'modf_view_group\':
            cate = View_Cate.objects.filter(id=id).first()
            groupList = [int(i) for i in request.POST.getlist(\'groups[]\')]
            addGroupsList = list(set(groupList).difference(set(cate.user_group.all())))
            delGroupsList = list(set(cate.user_group.all()).difference(set(groupList)))
            for groupObj in delGroupsList:
                cate.user_group.remove(groupObj)
            for groupId in addGroupsList:
                appObj = Group.objects.filter(id=groupId).first()
                cate.user_group.add(grouppObj)
            return JsonResponse({\'code\': 200, \'msg\': \'修改成功\'})

大功告成
