如果angular2书写不规范,那么界面中调用对象属性是会报错的,因为没有初始化变量属性,所以比较复杂的数据类型最好在单独文件重定义,然后引入初始化。
1、定义

export class DetailInfo {
    constructor(
        public userid: string,
        public userNm: string,
        public qqNm: string,
        public instid: string,
        public instfullnm: string,
        public instnm: string,
        public cfname: string,
        public ctname: string,
        public rgstMblph: string,
        public ctcMod1: string,
        public ctcMod2: string,
        public inptChnl: string,
        public dataeSource: string,
        public createtime: string,
        public lsttmusetm: string,
        public lbl: Array<string>,
        public udflbl: string,
        public wxopenid: string,
        public smbsnestatus: string,
        public qqvldestatus: string,
        public vldqq: string,
        public chkuname: string,
        public lsttmchktm: string,
        public state: string
    ) {}
}

2、使用

import {DetailInfo} from "./detail-info";
@Component({
    selector: "contacts-detail",
    templateUrl: "./contacts-detail.component.html",
    styleUrls: [
        "../contacts.component.css"
    ]
})
export class ContactsDetailComponent implements OnInit {
// 使用定义的数据类型
    detailInfo: DetailInfo;
    constructor() {
    
    }
    ngOnInit() {
    // 初始化
        this.detailInfo = {
            userid: "",
            userNm: "",
            qqNm: "",
            instid: "",
            instfullnm: "",
            instnm: "",
            cfname: "",
            ctname: "",
            rgstMblph: "",
            ctcMod1: "",
            ctcMod2: "",
            inptChnl: "",
            dataeSource: "",
            createtime: "",
            lsttmusetm: "",
            lbl: [],
            udflbl: "",
            wxopenid: "",
            smbsnestatus: "",
            qqvldestatus: "",
            vldqq: "",
            chkuname: "",
            lsttmchktm: "",
            state: ""
        };
    }
    selectValue(data: any) {
        // 这里就可以调用方法的属性,不会报错,和界面是一样的
        this.detailInfo.instnm = this.detailInfo.instfullnm.split("--")[1];
        this.detailInfo.instid = this.detailInfo.instfullnm.split("--")[2];
        this.detailInfo.instfullnm = this.detailInfo.instfullnm.split("--")[0];
    }
}
