摘要：本文将介绍在 Angular4 项目中配置 Wijmo5 UI控件，文中采用的 Angular 版本为 4.0.0，Wijmo 版本为 C1Wijmo-Eval_5.20171.300

下载 Wijmo5 官方文件

C1Wijmo-Eval_5.20171.300.zip

创建好 Angular4 项目

文中不介绍搭建 Angular 开发环境的过程，需要的可以参考官方提供的 快速入门

创建项目 ng new wijmo ，并测试 ng serve ，运行成功过后再进行接下来的配置。

配置 Wijmo5

解压文件后进入 NpmImages 文件夹，拷贝 wijmo-amd-min 到 Angular项目 wijmo 的 npm_modules 目录下且改名为 wijmo，并 wijmo 项目的 package.json 文件中的 dependencies 中添加配置如下

3
"dependencies": {
    "wijmo": "^5.20171.300"
}

将 “C1Wijmo-Eval_5.20171.300\Dist\styles” 拷贝到 Angular 项目的 src 目录下，并在 src/styles.css 文件中添加 wijmo 自带的样式文件

1
@import "styles/wijmo.min.css";

编写代码

app/app.modules.ts 代码如下：

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { WjInputModule } from 'wijmo/wijmo.angular2.input';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    WjInputModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'app';

  value: number = 123;

  change() {
    alert("my WjInputNumber value is " + this.value);
  }
}

个人博客原文：保存 Hexo 博客源码到 GitHub

摘要：本文介绍在使用 Hexo 博客的时候，怎么保存博客原文。

我们在使用 Hexo 来写博客的时候，我们将博客搭建在 GitHub 上后，当我们使用 hexo d 部署到 GitHub 上，其实没有把我们编写的 xxx.md 原博客文档保存上去，而只是生成一些博客需要的静态的页面。假设我们硬盘坏了，数据无法恢复，那么我们的博客源文档也会不见，所以最好我们是把源代码也托管到 GitHub 上， 这个也有一个好处就是你在其他电脑上也可以同步编写博客。接下来就讲述如何实现。

建立分支

因为 master 分支是存放 Hexo 博客生成的页面，所以只能创建一个分支来保存博客的源代码在你的 GitHub 。例如，我创建了一个分支叫 save

创建分支 save

更改默认分支

更改我们的项目的默认分支为 save

更改默认分支 save

clone 项目

clone 你的项目到你的 Hexo 目录下。例如我的是执行下面的命令：

1
git clone https://github.com/1CSH1/1CSH1.github.io.git

执行命令

执行下面的命令将你的博客的原文配置等等保存到分支 save 上

1
2
3
4
git remote add origin https://github.com/1CSH1/1CSH1.github.io.git
git add .
git commit -m "your description"
git push origin save

配置

确认你的 _config.yml 配置是提交到 master 分支

1
2
3
4
deploy:
  type: git
  repository: git@github.com:1CSH1/1CSH1.github.io.git
  branch: master

通过以上的配置，就可以把 Hexo 博客的源文件配置等到保存到 GitHub 上。
