遍历打字稿中的地图对象列表

Question

我有一个打字稿，可以对java类中的API方法进行调用。此方法返回地图列表。

Typescript文件看起来像这样：在这里，我试图从[ { _id: 5f77bc653887221a703415df, watercrafts: [ { _id: 5f77bc653887221a703415d3, class: 'sail', name: 'Gone with the Wind', __v: 0 } ] }, { _id: 5f77bc653887221a703415e0, watercrafts: [ { _id: 5f77bc653887221a703415d4, class: 'yatch', name: 'Liquid Gold', __v: 0 } ] }, { _id: 5f77bc653887221a703415e1, watercrafts: [ { _id: 5f77bc653887221a703415d5, class: 'ship', name: 'Jenny', __v: 0 } ] }, { _id: 5f77bc653887221a703415e5, watercrafts: [ { _id: 5f77bc653887221a703415dd, class: 'yatch', name: 'Audrey', __v: 0 } ] }, { _id: 5f77bc653887221a703415e5, watercrafts: [ { _id: 5f77bc653887221a703415dc, class: 'sail', name: 'Swell Shredder', __v: 0 } ] }, { _id: 5f77bc653887221a703415e5, watercrafts: [ { _id: 5f77bc653887221a703415de, class: 'ship', name: 'Jenny IV', __v: 0 } ] } ] 中检索数据，但是当我循环遍历它时，它显示了[Object Object]，我想看看需要做什么。打字稿文件端从Java类检索数据集。

dataBody

Java类：

*public populatePeople(hyperfindId: number) {
            this.getGridInstance()
            //this.peopleList= [];
            this.personIds = [];
            this.personNameById = new Map<string, string>();  
            this.pokerEntryService.getPeopleByHyperfind(hyperfindId, this.tbSite, this.tbDivision, this.tbDepartment).subscribe((data)=>{
                                 
                    let dataBody = JSON.parse(JSON.stringify(data.body));
                    
                    //Need to retrieve data here.
                    
                    if(dataBody.maxExceeded === true){
                           this.showError = true;
                           this.alertService.createAlert('WARNING', this.edapLocaleConvertor.convertLocaleMessage('peopleEditor.maxPeopleExceeded'));       
                    }
             },
             err => {
                    this.showErrorMessage(err);
             });
        }**

此问题已解决。我将哈希图更改为使用值的对象。现在工作正常。
