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.

然后是调用处理:
<span>//</span><span>处理ajax请求</span> <span>if</span>(<span>isset</span>(<span>$_POST</span>['submit'<span>])){ </span><span>//</span><span>是否自动执行批处理</span> <span>$isAuto</span> = <span>$_POST</span>['zip'] === 'true' ? <span>true</span> : <span>false</span><span>; </span><span>//</span><span>处理类型</span> <span>$type</span> = <span>$_POST</span>['type'<span>]; </span><span>$c</span> = Factory::create(<span>$type</span>,<span>$isAuto</span><span>);<br /> //接口方法 </span><span>$c</span>-><span>request(); </span><span>$c</span>-><span>render(); }</span><span>else</span><span>{ </span><span>echo</span> '请使用静态页访问本程序:<a href="index.html">点此进入</a>'<span>; }</span>
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:
<span>public</span> <span>function</span> runBat(<span>$name</span><span>){ </span><span>if</span>(!<span>file_exists</span>(<span>$name</span>) || !<span>$this</span>-><span>isAuto){ </span><span>return</span><span>; } </span><span>//</span><span>转入后台处理</span> @<span>exec</span>(<span>pclose</span>(<span>popen</span>("start /B ". <span>escapeshellcmd</span>(<span>$name</span>), "r"<span>))); }</span>
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:
<span>$files</span> = <span>glob</span>(<span>$path</span>.'/*.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:
<span>/*</span><span>* * 选项卡类 * @param {string} id 选项卡的ID </span><span>*/</span> <span>function</span><span> Tabs(id){ </span><span>var</span> node = document.querySelector('#'+<span>id); </span><span>var</span> selected = node.querySelector('.selected'<span>); </span><span>this</span>.selected =<span> selected; </span><span>this</span>.node =<span> node; </span><span>this</span><span>.bindEvent(); } </span><span>/*</span><span>* * 切换选项卡 * @param {object} event 事件 * @return {[type]} [description] </span><span>*/</span><span> Tabs.prototype.change </span>= <span>function</span><span>(event){ </span><span>var</span> element =<span> event.target; </span><span>if</span>(element.tagName.toLowerCase()=='li'<span>){ </span><span>if</span>(element.className=='selected'<span>){ </span><span>return</span><span>; } }</span><span>else</span><span>{ </span><span>while</span>(element != <span>this</span><span>.node){ element </span>=<span> element.parentNode; </span><span>if</span>(element.tagName.toLowerCase()=='li'<span>){ </span><span>break</span><span>; } } </span><span>if</span>(element == <span>this</span>.node) <span>return</span><span>; } </span><span>this</span>.selected.removeAttribute('class'<span>); element.className </span>= 'selected'<span>; </span><span>this</span>.selected =<span> element; </span><span>this</span><span>.content(); } Tabs.prototype.content </span>= <span>function</span><span>(){ </span><span>var</span> form =<span> document.form1; </span><span>switch</span>(<span>this</span><span>.getTabType()){ </span><span>case</span> 'js'<span>: form.style.display </span>= 'block'<span>; form.children[</span>0].innerHTML = '自动压缩JS'<span>; </span><span>break</span><span>; </span><span>case</span> 'css'<span>: form.style.display </span>= 'block'<span>; form.children[</span>0].innerHTML = '自动压缩CSS'<span>; </span><span>break</span><span>; </span><span>default</span><span>: } }</span>
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!
