Javascript的StringBuffer

如果page loading過慢, 外加有使用迴圈串字串的話, 可以使用string buffer來改善串字串的速度.

function stringBuffer(){
  this._string=new Array;
  /*如果執行此function帶有參數則為true,
   example: new stringBuffer('test');*/
  if(arguments.length==1)
     this._string.push(arguments[0]);
}
stringBuffer.prototype.append = function(str){
  this._string.push(str);
}
stringBuffer.prototype.toString = function(){
  return this._string.join('');//javascript的array最後放''為結尾轉為字串, ex:C語言為'\0'
}
//使用範例
function init(){
  var strbuff=new stringBuffer('first');//將init first push於陣列
  strbuff.append('second');//將second push於陣列
  strbuff.toString();//最後轉成字串, print:firstsecond
}

另外可以透過Google Page Speed測試網頁是否有變快

在Blogger文章中使用程式區塊

1.如下圖點選範本→編輯HTML

2.在</head>之前貼上下列程式碼

3.Blogger的程式碼要呈現在程式區塊中, 需要將tag <>之類的需要將轉成跳脫字元,
 <(&lt;)和>(&gt;),可以透過HTML Encoder轉換

4.再將轉換後的程式碼貼在tag中<pre class="brush:html">程式碼...</pre>
其中html就是你所要顯示程式語言的類型,從上面得知你所匯入的js檔中有支援那些語言.
example:<pre class="brush:js">, <pre class="brush:java">...etc

Beginning Eclipse(未完..待補)

Eclipse Home
Eclipse Download Page

.安裝plugins: Help->Install New Software...,如下圖, 輸入Name:自訂更新位置名稱, Location:更新網址
example:
              Name: jboss Tools
              Location: http://download.jboss.org/jbosstools/updates/stable/juno

接下來就可以勾選要安裝的plugins, 若是已經下載plugins的jar檔,則直接將jar檔放置在X:\eclipse\plugins\底下,再重啟eclipse即可.
