更新完成后触发函数

Question

当更新功能与 xsodata 一起使用时，我如何执行功能顺序？！到目前为止，我的问题是更新树 table 然后打开更新前打开的前几行。我正在使用 setTimeout 函数，但我知道它实际上不是这个问题的答案。

tEvents.unbindAggregation("rows");
tEvents.bindAggregation("rows",{
    path: "events>/prg_years(ID_SCENARIO=" + filterKRVR.scenario + ",I_YEAR=" + filterKRVR.year + "m)" + "/HisGTO",
    parameters: {
        navigation: {
            'prg_gto':  "HisPIPE",
            'prg_pipe': "HisKS",
            'prg_ks':   "HisLK"
        },
    }
}); 

tEvents.getModel('events').refresh();

        

if(bookmark.gto!==null){
    var that = this;
    setTimeout(function(){
        var t = that.getView().byId('eventsKRVR');
        t.expand(bookmark.gto);
    },800)
}
if(bookmark.pipe!==null){
    var that = this;
    setTimeout(function(){
        var t = that.getView().byId('eventsKRVR');
        t.expand(bookmark.pipe);
    },1500)
}
if(bookmark.ks!==null){
    var that = this;
    setTimeout(function(){
        var t = that.getView().byId('eventsKRVR');
        t.expand(bookmark.ks);
    },2500)
}

有人有什么建议吗？

我通过 attachRequestCompleted 解决了这个问题。

tEvents.getModel('events').attachRequestCompleted(function (oEvent) {
                    var url = oEvent.mParameters.url;
                    if(url.indexOf('prg_years') >= 0){
                        setTimeout(function(){
                            that.doRefresh();
                            setTimeout(function(){
                                tEvents.expand(bookmark.gto);
                            },100)
                        },100)
                    }else if(url.indexOf('prg_gto') >= 0){
                        setTimeout(function(){
                            that.doRefresh();
                            setTimeout(function(){
                                tEvents.expand(bookmark.pipe);
                            },100)
                        },100)
                    }else if(url.indexOf('prg_pipe') >= 0){
                        setTimeout(function(){
                            that.doRefresh();
                            setTimeout(function(){
                                tEvents.expand(bookmark.ks);
                            },100)
                        },100)
                    }else if(url.indexOf('prg_ks') >= 0){
                        setTimeout(function(){
                            that.doRefresh();
                            setTimeout(function(){
                                $('.sapUiScrollBar div').scrollTop(32*bookmark.lk-64);
                            },100)
                        },1000)
                    }
                });

还对 table 刷新进行了破解，因为有时渲染 table 会出现问题，我在这里问了这个问题：
