函数中对象名的传参形式

    function setNumber($this,g,d,url){
        var gid = $this.parent().attr("data-id");
        var eids = $("#hidden").text();
        var params = {};
        params[g] = gid; //传参
        params[d] = eidsl;//传参
       if(eids==""){
            layer.alert("勾选项为空，请选择");
            return false;
        }else{
            $.ajax({
                method: ‘put‘,
                url: url,
                data: params,
                success:function(data){
                    if(data){
                        $("#modal").modal("hide");
                    }else{

                    }
                }
            })            
        }

    }
