Note:
You can also add your own JavaScript code to all pages.  ^{(See note 2)}
To add JavaScript code, edit the js_ExtraCode.js file or create a new JS file in the WebWindow directory.
In the options window, External JS file path must point to this file.

• ww_external_JS_Code = true if a JS file has been selected in the options window.
• ww_external_JS_File is the file name of your JavaScript code.
• ww_external_JS_FileFound = true if the file exists.
• ww_external_JS_FileSize is the size of the JS file in bytes.
• If ww_JS_privacy = true, then the above values will return N/A, undefined or false, but your JavaScript code will still be available.
  
  To disable your JavaScript code, set External JS file path to - None -
  
  
  Note 1:
  WebWindow version 3.18.0045 or later:
  
  • The extra JavaScript code only works with Windows 7 service pack 1 or later operating systems.
    
  • Windows Vista supports JavaScript version messages only.
    
  • You must have Internet Explorer 10 or later installed, to use the extra JavaScript code.
    
  • The web page must not be listed and ticked in the advanced options window.
    
  Note 2:
  
  • The size of the JavaScript file is limited to   5,000 bytes with version 3.18.0045 of WebWindow.
  • The size of the JavaScript file is limited to 10,000 bytes with version 3.19.0046 of WebWindow.
  • You can add a page to a list of pages that will not add any extra JavaScript code with version 3.20.0047 of WebWindow.
    Click on Options, Advanced options.
    (If  Don't add WebWindow extra JavaScript code  is set, then ww_name, ww_version and ww_ScriptEnabled will still return a value)
  Note 3:
  
  • WebWindow versions before 3.18.0045 do not support the extra JavaScript code and messages.
    
  • WebWindow version 3.18.0045 to version 3.19.0046 support the extra JavaScript code, but not in frames or iFrames.
    
  • WebWindow version 3.20.0047 and later support the extra JavaScript code in frames, iFrames and frames in frames.
    
  Note 4:
  WebWindow version 3.20.0047 or later:
  
  • Due to the large area size returned by some Javascript values, you must also add a HTML tag to enable the code.
    
  • Pages that don't need the values will run faster without the new HTML tag.
    
  • You do not need closing tags. Eg. After <ww_Read:ScreenFonts> you do not need </ww_Read:ScreenFonts> to close the tag.
    (You can use <ww_Read:ScreenFonts/> instead of <ww_Read:ScreenFonts>  if you wish)
    
  • The tags should be before any Javascript code, near the top of the page.
    
  • You must be using the correct privacy level as set in the options window.
    
  • The data is listed in load order.
    To list it in alphabetical order, use the Javascript .sort() function.
    Eg.
    

      <ww_Read:ScreenFonts>
      <SCRIPT LANGUAGE="JavaScript">
      <!--
        try {
          var temp_WW_Version = ww_version;
        }
        catch(err){
          var temp_WW_Version = 0;
        }
        if(temp_WW_Version>="3.20."){
          if(ww_JS_privacyLevel>=1){
            // Next line will sort list in to alphabetical order.
            ww_ScreenFontList = ww_ScreenFontList.sort();
            // Display the full list of screen fonts.
            for(localLoop=0; localLoop<ww_ScreenFontList.length; localLoop=localLoop+1){
              this.document.write("<FONT FACE=\""+ww_ScreenFontList[localLoop]+"\">\n");
              this.document.write(ww_ScreenFontList[localLoop]+"<BR>\n");
              this.document.write("</FONT>\n");
            }
          }
        }
      // -->
      </SCRIPT>

  Note 5:
  Due to changes with Windows 10 from previous versions of Windows,
  WebWindow version 0.06.0033 to version 3.20.0048 returns the wrong values with the following:
  Javascript values:
  
  • ww_OEM_number
    
  • navigator.userAgent
    
  • ww_computerPlatform[...]
    Javascript function:
    
  • ww_checkComputerPlatform(ID, Major version, Minor version, Build number)
    ww_checkComputerPlatform(2, 6,2, 9200)=true with Windows 8.0, 8.1 and 10 and WebWindow version 3.20.0048 and earlier. (Wrong value)
    ww_checkComputerPlatform(2,10,0,10240)=true with Windows 10 and WebWindow version 3.21.0049 and later. (Correct value)
    

    ww_computerPlatform[..]	Old incorect values: WebWindow 3.20.0048 or before.	New corect values: WebWindow 3.21.0049 or later.
