Question

本网站的基本理念是ebay克隆。对于这个问题，我正在尝试建立出价网页。

链接到没有nodes_modules文件夹的完整项目：enter link description here

我正在尝试制作一个变量，用于显示用户点击按钮后输入的出价。我不确定是否需要创建一个带有一组出价的构造函数。

.ts文件代码：

import {Component, OnInit} from 'angular2/core';
import {RouteConfig, ROUTER_DIRECTIVES} from 'angular2/router';
import {Hero} from './hero';
import {HeroService} from './hero.service';

@Component({
selector: 'BiddingPageComponent',
templateUrl: 'app/BiddingPage.component.html',
styleUrls: ['app/BiddingPage.component.css'],
providers: [HeroService],
directives: [ROUTER_DIRECTIVES]
})
export class BiddingPageComponent
{
       var slot1 = 0;
       myFunction() 
      {
           slot1 = "{{slot1}}";
      }
}

我需要更改.html文件的唯一部分：

投标位置1：

<input type="number" name="fname" value={{slot1}}><br>

完整的.html文件代码：

<html>
<center>
  <h3>Bidding Page</h3>
</center>
<p></p>
<p></p>
<form>
  <img src="http://weknowyourdreamz.com/images/apple/apple-05.jpg" alt="Apple" style="width:100px;height:100px;">

  <label for="name">Description of item’s current condition: </label>

    <button onclick="myFunction()">Click here to bid.</button>

因为您正在使用Typescript，只需从var

中删除var slot1 = 0;即可
