Angular 4入门教程系列：14：PrimeNG的使用方式

这篇文章介绍一下Angular的老牌UI组件库PrimeNG，并演示一下如何使引入PrimeNG到项目之中。

Why PrimeNG

使用PrimeNG有很多原因，比如

• 70多个完善的组件
• 开源
• 提高生产性
• 多种主题
• 高度可定制的模板
• 移动端用户体验的增强

事前准备

安装node

详细可以参照：http://blog.csdn.net/liumiaocn/article/details/78510679

[root@angular ~]# npm -v5.5.1[root@angular ~]# [root@angular ~]# node -vv9.1.0[root@angular ~]#

安装angular-cli

安装命令：npm install -g @angular/cli –unsafe-perm

[root@angular ~]# npm install -g @angular/cli --unsafe-perm/usr/local/npm/node/bin/ng -> /usr/local/npm/node/lib/node_modules/@angular/cli/bin/ng> node-sass@4.6.1 install /usr/local/npm/node/lib/node_modules/@angular/cli/node_modules/node-sass> node scripts/install.jsDownloading binary from https://github.com/sass/node-sass/releases/download/v4.6.1/linux-x64-59_binding.nodeDownload complete  ] - :Binary saved to /usr/local/npm/node/lib/node_modules/@angular/cli/node_modules/node-sass/vendor/linux-x64-59/binding.nodeCaching binary to /root/.npm/node-sass/4.6.1/linux-x64-59_binding.node> node-sass@4.6.1 postinstall /usr/local/npm/node/lib/node_modules/@angular/cli/node_modules/node-sass> node scripts/build.jsBinary found at /usr/local/npm/node/lib/node_modules/@angular/cli/node_modules/node-sass/vendor/linux-x64-59/binding.nodeTesting binaryBinary is finenpm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.3 (node_modules/@angular/cli/node_modules/fsevents):npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})+ @angular/cli@1.5.0added 148 packages and updated 1 package in 122.371s[root@angular ~]#

设定link

[root@angular ~]# ln -s /usr/local/npm/node/lib/node_modules/@angular/cli/bin/ng /usr/local/bin/ng[root@angular ~]# which ng/usr/local/bin/ng[root@angular ~]# ng version    _                      _                 ____ _     ___   / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|  / △ \ | '_ \ / _` | | | | |/ _` | '__|   | |   | |    | | / ___ \| | | | (_| | |_| | | (_| | |      | |___| |___ | |/_/   \_\_| |_|\__, |\__,_|_|\__,_|_|       \____|_____|___|               |___/Angular CLI: 1.5.0Node: 9.1.0OS: linux x64Angular: ...[root@angular ~]# 

安装typescript

[root@angular ~]# npm install -g typescript/usr/local/npm/node/bin/tsc -> /usr/local/npm/node/lib/node_modules/typescript/bin/tsc/usr/local/npm/node/bin/tsserver -> /usr/local/npm/node/lib/node_modules/typescript/bin/tsserver+ typescript@2.6.1updated 1 package in 9.327s[root@angular ~]# 

创建cli项目骨架

设定.angular-cli.json

如下，设定font-awesome和primeng相关的css：

      "styles": [        "styles.css",        "../node_modules/primeng/resources/themes/omega/theme.css",        "../node_modules/primeng/resources/primeng.min.css",        "../node_modules/font-awesome/css/font-awesome.css"      ],

修改HTML模板

修改app.component.html

[root@angular app]# cat app.component.html <!--The content below is only a placeholder and can be replaced.--><div style="text-align:center">  <h1>    Welcome to {{title}}!  </h1></div><h3 class="first">Addons</h3><div class="ui-g ui-fluid">    <div class="ui-g-12 ui-md-4">        <div class="ui-inputgroup">            <span class="ui-inputgroup-addon"><i class="fa fa-user"></i></span>            <input type="text" pInputText placeholder="Username">                 </div>    </div>    <div class="ui-g-12 ui-md-4">        <div class="ui-inputgroup">            <span class="ui-inputgroup-addon">$</span>            <input type="text" pInputText placeholder="Price">               <span class="ui-inputgroup-addon">.00</span>              </div>    </div>    <div class="ui-g-12 ui-md-4">        <div class="ui-inputgroup">            <span class="ui-inputgroup-addon">www</span>            <input type="text" pInputText placeholder="Website">              </div>    </div></div><h3>Multiple Addons</h3><div class="ui-g">    <div class="ui-g-12">        <div class="ui-inputgroup">            <span class="ui-inputgroup-addon"><i class="fa fa-credit-card"></i></span>              <span class="ui-inputgroup-addon"><i class="fa fa-cc-visa"></i></span>               <input type="text" pInputText placeholder="Price">             <span class="ui-inputgroup-addon">$</span>              <span class="ui-inputgroup-addon">.00</span>              </div>    </div></div>[root@angular app]#

结果确认
