将数组导入对象-角度2+

我有一个服务可以让我获得类型数组:

ngOnInit() {
    this.coreService.getByType( this.name ).subscribe(
            response => { this.handleSuccess( response ); },
            error => { console.error( error ); });

}

handleSuccess( coreTypes ) {
    var data = [];
    var pushedItems = [];
    coreTypes.forEach( ( coreType ) => {
        var entriesForType = [];
        entriesForType.push( coreType );    
            if ( entriesForType.length > 0 ) {
                entriesForType.forEach( entry => this.data.push( entry ) );
                this.data = data;
            if (data.length > 0) {
                data.forEach( d =>  this.item.value = d && pushedItems.push(this.item));
            }
                if(this.gridOptions.api !== null){
                    this.gridOptions.api.setRowData( this.pushedItems );
                }
            } 
    });
}

当前,this.data正在创建这样的me数组 this.data = ["one","two","three"]

我需要的是创建一个这样的对象数组

pushedItems = [{value:"one"},{value:"two"},{value:"three"}];

i定义了项:对象;和在contstructor中 this.item = {value:""};

但在功能上,当我设置 this.item.value = d ……它不断向我显示错误“属性”value“在类型”object“上不存在”…是否有助于实现类似pusheditems的数组?
