這兩天一直研究如何通過代碼來實現對IE和FF裡面設置的操作，來達到更改IE中的Script或者是JavaScript的狀態，是disabled還是enabled。以下介紹的心得暫時還不支持其它浏覽器。
暫時發現的方案有2個（以IE為例）
其一，用自動化的某個工具，抓取IE的process id等，然後抓取IE的那些files，tools，菜單項，一步一步的點擊，抓取，然後再點擊，保存。
其二，寫代碼，修改現有的一些能夠更改的資源，實現其狀態的讀取和修改。
對於以上的兩個方案，本文只實現了後者，原因是前者需要的自動化工具不好確定，就算是確定了也需要一段時間對環境的配置，文檔的閱讀，熟悉那些dll等等，這會花費大量的時間。而對於後種解決方案來說，會省時。
IE
注冊表詳細信息如下：http://support.microsoft.com/kb/182569
Internet Explorer 安全區域注冊表項說明中有一部分提到的如下的內容，那麼我們就可以通過修改注冊表中的選項來達到我們預期的要求。
/// <summary>
/// Get Current Script state of IE.
/// </summary>
/// <param name="regPath"></param>
/// <returns>true ---> allow Script.</returns>
public static bool GetIECurrentScriptState(string regPath)
{
bool ret = false;
RegistryKey regSubkey = null;
regSubkey = Registry.CurrentUser.OpenSubKey(regPath, true);
if (regSubkey.GetValue("1400").ToString() == "0")
{
ret = true;
}
if ((int)regSubkey.GetValue("1400") == 3)
{
ret = false;
}
return ret;
}
以下是對IE中注冊表的改變：
/// <summary>
/// Disable IE Scripts.
/// </summary>
public void DisableIEScripts()
{
RegistryKey regSubKey = null;
regSubKey = Registry.CurrentUser.OpenSubKey(regPath, true);
regSubKey.SetValue("1400", 0x3);
}
起初我以為如此修改注冊表的信息也會帶來其他浏覽器的改變，但是結果並不然。
FireFox
當我企圖在FF裡面尋找相關注冊表修改的時候，並沒有找到相關選項，於是換一種思路。最終在當前用戶的firefox文件中，找到了一個叫做pref.js的文件。裡面有也許有一行代碼，user_pref("javascript.enabled", false); 。這就代表了javascript被禁止了。如果為true或者沒有的話，那麼都代表了允許狀態。而該文件的文件夾9acap8nw.default如此帶有default字樣的，也是隨著不同的機器安裝不同的客戶端所不同的。而它的前面的目錄大概的C:\Documents and Settings\。。。\Application Data\Mozilla\Firefox\Profiles如此。不過會有這樣的文件夾也只是在windows server2003 和XP中有如此的目錄，具體問題還是需要具體分析的。
/// <summary>
/// Delete one line which contains the "javaScript.enabled.
/// </summary>
/// <param name="filePath">the path of js file.</param>
public static void DisableFFJaveScript(string filePath)
{
StringBuilder sb = new StringBuilder();
using (FileStream aStream = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.ReadWrite))
{
StreamReader aReader = new StreamReader(aStream, Encoding.UTF8);
StreamWriter aWriter = new StreamWriter(aStream, Encoding.UTF8);
aReader.BaseStream.Seek(0, SeekOrigin.Begin);
string streamLine = aReader.ReadLine();
bool isJSDisabled = false;
bool isJSFalse = false;
while (streamLine != null)
{
if (streamLine.Contains("javascript.enable") && streamLine.Contains("false"))
{
isJSFalse = true;
}
if (streamLine.Contains("javascript.enable") && streamLine.Contains("true"))
{
streamLine = streamLine.Replace("true", "false");
isJSDisabled = true;
}
sb.Append(streamLine + "\r\n");
streamLine = aReader.ReadLine();
}
if (!isJSDisabled && !isJSFalse)
sb.Append("user_pref(" + "\"javascript.enabled\"" + "," + " false);");
aReader.Close();
}
File.Delete(filePath);
AddToFile(filePath, sb.ToString());
}
附下全部源碼供大家分享。包括對當前文件路徑的組合，文件讀取，增刪改操作。IE，FF，狀態的讀取，改變。

後文：
有人就會問了，用鼠標隨便點點就能夠輕松實現的東西，為什麼還有寫這麼多亂七八糟的代碼呢？
我認為有幾點好處：
1.本例更適合使用在測試代碼中，通過此，可以計算開發代碼的code coverage
2.手工要比自動化效率低下，款且存在很大的誤差。
3.開發人員也可以此檢測當前用戶狀態，以改變不同的現實效果或者提示。
目前只是發現了FF和IE的操作，並且對IE8的注冊表修改還是有小小的不同。對於其他眾多浏覽器，大家有研究的可以給我提供些新鮮的信息和想法。一起交流學習，有疏漏的地方大家補充。
