我正在开发一个Angular2项目，并且创建了一个类作为主Component类：

import { Component, OnInit} from '@angular/core';

import { submitService } from './Common-functions/submit.service';

@Component({
selector: 'my-app',
template: `htmlCode`

})
export class AppComponent implements OnInit{ 
  hideTable = true;
  lengthOfRecords = 0;
  lowerLimit = 0;
  upperLimit = 5;
  prevButtonDisabled = true;
  nextButtonDisabled = false;

  //User inputs

constructor(private sService:submitService) { }

ngOnInit() {
    public submitToJSON() {

         //SumbitJSON Object
            var submitJSON = {
                //inputData 
                     };

            this.sService.POST(submitJSON);
     }

   public returnDetails() {

    this.listOfIDs = {//ListData};

            this.hideTable = false;
        var keys = Object.keys(this.listOfIDs);
            var len = keys.length;
            this.lengthOfRecords = len;
        }

    public prev() {
            if(this.lowerLimit <= 0) {
                ;
                }
            else {
                this.lowerLimit = this.lowerLimit - 6;
                this.upperLimit = this.upperLimit - 5;
                this.nextButtonDisabled = false;
                if(this.lowerLimit <= 0) {
                    this.prevButtonDisabled = true;
                    }
                }
            }
   public next() {
            if(this.upperLimit >= this.lengthOfRecords) {
                ;
                }
            else {
                this.lowerLimit = this.lowerLimit + 6;
                this.upperLimit = this.upperLimit + 5;
                this.prevButtonDisabled = false;
                if(this.upperLimit >= this.lengthOfRecords) {
                    this.nextButtonDisabled = true;
                    }
                }
            }

 getEntries(obj, from, to) {
        if(obj!=null) {
            var entries = [];
            for(var key in obj) {
                // extract index after `app`
                var index = key.substring(3);
                if(index >= from && index <= to) {
                    entries.push( obj[key]);
                }
            }
            return entries;
            }

 }

}

当我运行npm start（它将运行tsc -p ./）时，我得到以下两个错误：

app.appComponent.ts: error TS1128:Declaration or statement expected
app.appComponent.ts: error TS1128:Declaration or statement expected

在以下代码行中

---> public submitToJSON() {

     //SumbitJSON Object
        var submitJSON = {
            //inputData };

        this.sService.POST(submitJSON);
 }

在代码的最后一行。我已经修改了一整天的代码，只删除了OnInit相关的代码就修复了它。我做错了什么？我是Angular2的新手，所以任何信息都是有帮助的。我也在运行tsc版本3.1
