时下grunt非常的火啊,用着虽然很爽,但是它的配置确实很烦。如果之前没有用过,想要一下子熟练驾驭它,有一定的学习成本,而且还要装node这个大家伙,项目之初我们选择了compiler.jar这个轻量的工具进行打包。我一直在寻思着,如何编写一键打包工具。之前呢是手工的拼接好有的js文件,做成符合compiler.jar打包文件所要求的批处理文件,然后运行这个批处理,生成我们需要的js和css文件。随着js文件数量的增长,纯手工拼接这些文件的地址就变得非常考验人的耐心了,而且还容易漏掉或重复某些文件,于是“一键打包工具”的编写就变得刻不容缓了。下面是一个真实的index.html文件的一部分:

后面还有很长,bug,活人不能被尿憋死,办法总比问题多。我是会一点php的,php在处理文件方面是很拿手的,是时候让它发挥点作用了。于是我想到了用php去自动提出index里边的js和css,然后按指定的格式生成批处理文件,在后台用静默方式运行这个批处理,最后把结果返回给显示器。这样我就可以坐享其成了。想想都有点小激动哟,于是简单的写了一个界面.
接下来就是实现功能了,先不着急编写代码,分析下需求:
1. 遍历index.html文件,提取js文件或css文件.
2. 对这文件进行过虑,因为有些是注释掉的,有些是调式用的。
3. 生成对应的批处理文件
4. 执行批处理文件
5. 显示处理结果
即然有两种情况,我就用一个工厂模式来适配,方便以后扩展其它类型,目光要放长远一点。即然工厂都有了,那索性再来一个接口,约定都必需要实现“接收请求”和“输出结果”这两个接口。再想想处理js和css都可能会有相同的功能,让它们继承一个父类可以使代码复用,于是继承也先用上。目前的设计应当可以满足我的要求了,于是开始编写php代码.
php header("Content-type: text/html; charset=utf-8"); /** * 根据index.html文件中引用的js,生成compressJs.bat * @author frog <278500368@qq.com> * @date 2014-11-17 */ interface ICompress { /** * 处理用户请求 * @return [type] [description] */ public function request(); /** * 处理输出结果 * @return [type] [description] */ public function render(); } class BaseCompress { public $content; public $outPath; public $isAuto; public function __construct($isAuto=false){ $outPath = '_file'; if(!is_dir($outPath)){ mkdir($outPath); } $this->outPath = $outPath; $this->isAuto = $isAuto; } /** * 运行批处理 * @return [type] [description] */ public function runBat($name){ } } /** * 压缩javascript文件 * 合并javascript文件 */ class CompressJS extends BaseCompress implements ICompress { /** * 处理用户请求 * @return [type] [description] */ public function request(){ } /** * 处理输出结果 * @return [type] [description] */ public function render(){} } /** * 压缩样式文件 */ class CompressCSS extends BaseCompress implements ICompress { public function request(){ } /** * 处理输出结果 * @return [type] [description] */ public function render(){} } /** * 工厂类 */ class Factory { public static function create($type,$isAuto){ $ob = null; switch ($type) { case 'js': $ob = new CompressJS($isAuto); break; case 'css': $ob = new CompressCSS($isAuto); break; default: # code... break; } return $ob; } }
然后是调用处理:
//处理ajax请求 if(isset($_POST['submit'])){ //是否自动执行批处理 $isAuto = $_POST['zip'] === 'true' ? true : false; //处理类型 $type = $_POST['type']; $c = Factory::create($type,$isAuto);
//接口方法 $c->request(); $c->render(); }else{ echo '请使用静态页访问本程序:点此进入'; }
大致的骨架就出来了。具体的填码过程就比较简单了。稍微有点难度的就是执行批处理这个一方法.
是网上提供的方法,以后可能用的上,这里特意贴一下:
public function runBat($name){ if(!file_exists($name) || !$this->isAuto){ return; } //转入后台处理 @exec(pclose(popen("start /B ". escapeshellcmd($name), "r"))); }
在前面的index.html中,有一个name="noBuild"这个是我人为添加的,这是因为我要过滤这种标识的js文件,这样以后要过滤别的文件,也只要添加这个标识就可以了,不用改php代码。由于是内部使用,没有做表单项来指定工程的路径,默认就是index.html所处的上级目录即为工程目录。这样设计简化了操作,提高了效率。
关于遍历特定的文件,我推荐glob函数,很简洁的方案:
$files = glob($path.'/*.css',GLOB_NOSORT);
下面是工程目录结构图:
再来一张运行效果图:
最后是处理结果图:
终于不用写grunt的配置和安装node这个家伙了,再也不担心更新的时候,从svn上拉下来一堆node的东西,是时候和它们说再见了:
好像忘了展示前端代码了:
/** * 选项卡类 * @param {string} id 选项卡的ID */ function Tabs(id){ var node = document.querySelector('#'+id); var selected = node.querySelector('.selected'); this.selected = selected; this.node = node; this.bindEvent(); } /** * 切换选项卡 * @param {object} event 事件 * @return {[type]} [description] */ Tabs.prototype.change = function(event){ var element = event.target; if(element.tagName.toLowerCase()=='li'){ if(element.className=='selected'){ return; } }else{ while(element != this.node){ element = element.parentNode; if(element.tagName.toLowerCase()=='li'){ break; } } if(element == this.node) return; } this.selected.removeAttribute('class'); element.className = 'selected'; this.selected = element; this.content(); } Tabs.prototype.content = function(){ var form = document.form1; switch(this.getTabType()){ case 'js': form.style.display = 'block'; form.children[0].innerHTML = '自动压缩JS'; break; case 'css': form.style.display = 'block'; form.children[0].innerHTML = '自动压缩CSS'; break; default: } }
会前端和后端,就是这么任性。轻轻一点,告别烦恼!造自己的工具,让别人去苦逼吧,So easy!
