当我在chrome中运行我的页面时,我收到此错误"未捕获的syntaxerror意外令牌U".在Firefox中,我得到了"JSON.parse:意外的角色".我从php文件返回json数据,返回的json字符串有效.我用http://jsonlint.com/检查了它.任何帮助将不胜感激...谢谢.

这是返回的JSON字符串

我将开发一个简单的Angular 2应用程序.我使用Angular CLI创建了一个带路由的项目,并使用'ng generate component'命令向应用添加了几个组件.然后我在app-routing.module.ts中指定了路由,如下所示.

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { AboutComponent } from './about/about.component';
import { UserComponent } from './user/user.component';
import { ErrorComponent } from './error/error.component';
import { SpecialpageComponent } from './specialpage/specialpage.component';

const routes: Routes = [
  {
    path: '',
    component: HomeComponent
  },
  {
    path: 'about',
    component: AboutComponent
  },
    {
    path: 'user',
    component: UserComponent

    component: SpecialpageComponent

我正在尝试从mysql数据库收到的数据中绘制折线图.从数据库我有这些数据

我想绘制一个谷歌折线图,将x轴作为销售日期,将y轴作为product_name.但我希望每个产品都有多行,就像这样.

我可以绘制单个产品的图表.但无法想象如何在同一图表中为多个产品做到这一点.我正在使用JSON来获取图表的数据并使用MySQL数据库.任何帮助,教程将不胜感激.谢谢.

PS:我遵循本教程的单线图. http://www.kometschuh.de/GoogleChartToolswithJSON.html

我正在尝试用twitter4j库创建一个twitter客户端.但我仍然不清楚这些东西,我找不到一个好的教程.大多数教程都已过时.主要是我想知道,每当我创建Twitter客户端时,我是否必须使用OAuth？如果不是我应该怎么做(我的意思是,没有获得'消费者密钥'和'消费者保密',只需输入用户名和密码)？任何帮助,将不胜感激.谢谢.

我有一个列表定义,我有一个字段类型的用户,我希望它被多个选中.要做到这一点,我应该启用哪个属性,如果有的话？

 <Field ID="{A0372EB5-A947-41CA-A5FA-A34C29D2FB88}"
    Name="Employee"
    DisplayName="Employee"
    Type="User"
    Required="TRUE"
    StaticName="Employee"
    Group="SampleGroup"/>

任何帮助,将不胜感激.谢谢.
