HTML來源的Firefox錯誤信息（無法建立此連接錯誤顯示）

Question

我一直在試圖複製無法建立連接在我的網站之一的錯誤。我試圖從Firefox中的錯誤消息中複製HTML。我試圖找到默認錯誤頁面的來源（問題加載頁面）。我發現以下來源，當我選擇文本並在右鍵菜單中選擇選擇源。

<h1 id="errorTitleText">Unable to connect</h1> 
     </div> 

     <!-- LONG CONTENT (the section most likely to require scrolling) --> 
     <div id="errorLongContent"> 

     <!-- Short Description --> 
     <div id="errorShortDesc"> 
      <p id="errorShortDescText">Firefox can't establish 

如何找到完整的源代碼？

Answer 1

安裝firebug，然後在錯誤頁面上按下HTML選項卡。

<!-- ERROR ITEM CONTAINER (removed during loading to avoid bug 39098) --> 


    <!-- PAGE CONTAINER (for styling purposes only) --> 
    <div xmlns="http://www.w3.org/1999/xhtml" id="errorPageContainer"> 

     <!-- Error Title --> 
     <div id="errorTitle"> 
     <h1 id="errorTitleText">Server not found</h1> 
     </div> 

     <!-- LONG CONTENT (the section most likely to require scrolling) --> 
     <div id="errorLongContent"> 

     <!-- Short Description --> 
     <div id="errorShortDesc"> 
      <p id="errorShortDescText">Firefox can't find the server at www.bbc.co;uk.</p> 
     </div> 

     <!-- Long Description (Note: See netError.dtd for used XHTML tags) --> 
     <div id="errorLongDesc"> 
<ul> 
    <li>Check the address for typing errors such as 
    <strong>ww</strong>.example.com instead of 
    <strong>www</strong>.example.com</li> 
    <li>If you are unable to load any pages, check your computer's network 
    connection.</li> 
    <li>If your computer or network is protected by a firewall or proxy, make sure 
    that Firefox is permitted to access the Web.</li> 
</ul> 
</div> 

     <!-- Override section - For ssl errors only. Removed on init for other 
      error types. --> 

     </div> 

     <!-- Retry Button --> 
     <button id="errorTryAgain" autocomplete="off" onclick="retryThis(this);">Try Again</button> 

    </div> 

    <!-- 
    - Note: It is important to run the script this way, instead of using 
    - an onload handler. This is because error pages are loaded as 
    - LOAD_BACKGROUND, which means that onload handlers will not be executed. 
    --> 
    <script xmlns="http://www.w3.org/1999/xhtml" type="application/javascript">initPage();</script> 

對於CSS，它似乎使用：chrome://global/skin/netError.css

Answer 2

如果您無法連接到服務器，您將無法獲得任何源代碼。

如果您可以訪問源代碼，則必須按照定義進行連接。
