氚云表单前端通过后端获取数据自动填充子表

前端代码

    // 加载事件
    OnLoad: function() {
        var that = this;
        this.F0000004.BindChange( "key", function() {
            //前端返回后端的值
            var value = that.F0000004.GetValue();
            var teamValue = { teamValue: value };

            //子表对象
            var menu = that.D117002F3cdb9cfeac89421ebf1d17ddbf9d95f6;
            $.SmartForm.PostForm( "GetTeam", teamValue, function( data ) {
                //接收后端返回的数据
                var result = data.ReturnData;
                if( result != null ) {
                    //获取后台回传的子表数据
                    var ChildTable = result[ "tables" ];
                    //清除子表中的所有行
                    menu.ClearRows(); 
                    if( ChildTable == undefined ) {

                    } else {
                        for( var i = 0;i < ChildTable.length;i++ ) {
                            //填充子表
                            menu.AddRow( ChildTable[ i ].ValueTable.objectid, {
                                "D117002F3cdb9cfeac89421ebf1d17ddbf9d95f6.F0000043": ChildTable[ i ].ValueTable.F0000043,

                            })
                        }
                    }
                }
            },
                function( data ) { $.IShowWarn( "出错啦" ); }, false );
        })
    },
