小编use*_*794的帖子

我必须显示两个互斥的按钮'MARK COMPLETED'和'COMPLETED'.如果任务状态为OPEN,则需要显示"MARK COMPLETED",而如果任务状态已关闭,则需要显示"COMPLETED"按钮.

<div *ngFor="#task of tasks" class="demo-updates mdl-card mdl-shadow--2dp mdl-cell mdl-cell--4-col mdl-cell--4-col-tablet mdl-cell--12-col-desktop">
    <div class="mdl-card__title mdl-card--expand mdl-color--teal-300">
    <h2 class="mdl-card__title-text">{{task.taskname}}</h2>
    </div>
    <div class="mdl-card__supporting-text mdl-color-text--grey-600">
    {{task.taskdesc}}  {{task.taskstatus}}
    </div>
    <div class="mdl-card__actions mdl-card--border">                
                <a href="#" class="mdl-button mdl-js-button mdl-js-ripple-effect">{{task.assignedto}}</a>


    <a [routerLink]="['/AllTasks']" *ngIf="{{task.taskstatus}}='OPEN'" class="mdl-button mdl-js-button mdl-js-ripple-effect" (click)="onClickMark(task)">Mark Completed</a>
    <a [routerLink]="['/CompletedTasks']" *ngIf="{{task.taskstatus}}='CLOSED'" class="mdl-button mdl-js-button mdl-js-ripple-effect">Completed</a>


</div>    

我试过了*ngIf="{{task.taskstatus}}='OPEN'",但它不起作用.有任何想法吗 ？

由于某种原因,fileSaver未被映射.angular2-jwt工作正常.

我做npm install file-saver -save了文件保护程序,然后引用如下(我有一个gulp任务将js文件移动到libs目录,我看到那里的文件)

在index.htmlI中已将脚本包含在src和system.config中

    <script src="libs/file-saver/FileSaver.js"></script>

<!-- 2. Configure SystemJS -->
    <script>
      System.config({
        packages: {        
          app: {
            format: 'register',
            defaultExtension: 'js'
          } 
        } ,
        map: {
          "angular2-jwt": "libs/angular2-jwt/angular2-jwt.js"
          ,"fileSaver":"libs/file-saver/FileSaver.js"
        }
      });
      System.import('app/bootstrap')
            .then(null, console.error.bind(console));
    </script>

component.ts

这里没有找到fileSaver

import {SaveAs} from 'fileSaver';     

我得到的错误就是这个

 error TS2307: Cannot find module 'fileSaver'.   

知道这里有什么问题吗？

我在oracle中有一个表,其中所有列的行都必须使用起始值500更新并递增1.

我试图在网上找到类似的东西但却无法获得任何有用的东西.oracle和PL/SQL不是我的专长.任何帮助,将不胜感激.

我在应用程序中有一个搜索功能.当用户点击搜索按钮时,数据在[(ngModel)]中被捕获并传递给服务,URL被重定向到搜索组件的html.该服务被注入"搜索"组件并显示数据.

现在,当用户输入新的搜索词时,我想刷新现有的搜索组件.这样做的正确方法是什么？

search.component.ts

import { Component, OnInit } from '@angular/core';
import { DataService } from '../service/data.service';

@Component({
selector: 'app-search',
templateUrl: './search.component.html',
styleUrls: ['./search.component.css']
})
export class SearchComponent implements OnInit {

userInput : string; 
constructor(private data : DataService) { }

ngOnInit(){
    this.search();
}

search(){

    this.userInput = this.data.searchData;
    console.log('in search init  ' + this.userInput);
    this.data.searchData = "";
 }
}

app.component.ts

import { Component } from '@angular/core';
import { DataService } from './service/data.service';


@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

我试图将一些数据保存到H2数据库中.但我一直得到架构未找到错误消息,如下所示.

我试图使用索引文件中的system.config从我的angular2项目中的node_modules映射此Auth0模块.但我在浏览器控制台中收到404错误

索引文件

<!-- 2. Configure SystemJS -->
<script>
  System.config({
    packages: {        
      app: {
        format: 'register',
        defaultExtension: 'js'
      },
      "/angular2-jwt": {
      "defaultExtension": "js"
      }        
    },
    map: {
      "angular2-jwt": "node_modules/angular2-jwt/angular2-jwt"
    }
  });
  System.import('app/bootstrap')
        .then(null, console.error.bind(console));
</script>

控制台错误如下

我已将脚本包含在索引文件中,如下所示
