bug css html index php

時下grunt非常的火啊，用著雖然很爽，但是它的配置確實很煩。如果之前沒有用過，想要一下子熟練駕馭它，有一定的學習成本，而且還要裝node這個大傢伙，計畫之初我們選擇了compiler.jar這個輕量的工具進行打包。我一直在尋思著，如何寫一鍵打包工具。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次文件，然後運行這個批處理，生成我們需要的js和css文件。隨著js檔案數量的成長，純手工拼接這些文件的地址就變得非常考驗人的耐心了，而且還容易漏掉或重複某些文件，於是「一鍵打包工具」的編寫就變得刻不容緩了。下面是一個真實的index.html檔案的一部分：

登入後複製

後面還有很長，bug,活人不能被尿憋死，辦法總比問題多。我是會一點php的，php在處理文件方面是很拿手的，是時候讓它發揮點作用了。於是我想到了用php去自動提出index裡邊的js和css，然後按指定的格式產生批次文件，在後台用靜默方式運行這個批處理，最後把結果回傳給顯示器。這樣我就可以坐享其成了。想想都有點激動喲，於是簡單的寫了一個介面.

接下來就是實現功能了，先不急著寫程式碼，分析下需求：

1. 遍歷index.html文件，提取js檔案或css檔案.

2. 對這文件進行過慮，因為有些是註解掉的，有些是調式用的。

3. 產生對應的批次檔

4. 執行批次檔

5. 顯示處理結果

即然有兩種情況，我就用一個工廠模式來適配，方便以後擴展其它類型，目光要放長遠一點。即然工廠都有了，那索性再來一個介面,約定都必需要實現「接收請求」和「輸出結果」這兩個介面。再想想處理js和css都可能會有相同的功能，讓它們繼承一個父類別可以讓程式碼重複使用，於是繼承也先用上。目前的設計應當可以滿足我的要求了，於是開始寫php程式碼.

然後是呼叫處理：

<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>{

大致的骨架就出來了。具體的填碼流程就比較簡單了。稍微有點難度的就是執行批處理這個一方法.

是網路上提供的方法，以後可能用的上，這裡刻意貼一下：

<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，有一個name="noBuild"這個是我人為添加的，這是因為我要過濾這種標識的js文件，這樣以後要過濾別的文件，也只要添加這個標識就可以了，不用改php程式碼。由於是內部使用，沒有做表單項目來指定工程的路徑，預設就是index.html所處的上級目錄即為工程目錄。這樣設計簡化了操作，也提高了效率。

關於遍歷特定的文件，我推薦glob函數，很簡潔的方案：

<span>$files</span> = <span>glob</span>(<span>$path</span>.'/*.css',GLOB_NOSORT);

再來一張運行效果圖：

  

最後是處理結果圖：

終於不用寫grunt的配置和安裝node這個傢伙了，再也不擔心更新的時候，從svn上拉下來一堆node的東西，是時候和它們說再見了：

好像忘了展示前端程式碼了：

<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>*

 </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>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>(){

會前端和後端，就是這麼任性。輕輕一點，告別煩惱！造自己的工具，讓別人去苦逼吧，So easy!
