AIR 常用技巧

1.air打開關聯類型文件

如果該應用程序是由於文件類型關聯而被調用，則文件的完整路徑將包含在命令行參數中。

應用程序可通過以下方法處理 invoke 事件：即向其 NativeApplication 對象註冊偵聽器，

NativeApplication.nativeApplication.addEventListener(InvokeEvent.INVOKE, onInvokeEvent); 

air.NativeApplication.nativeApplication.addEventListener(air.InvokeEvent.INVOKE, onInvokeEvent);

2.air 打開系統文件目錄

var file:File = new File(directoryPath);
file.openWithDefaultApplication();

3.AIR NativeProcess 調用bat

<span style="white-space: pre;"><span style="font-family:Arial, Helvetica, sans-serif;"><span style="background-color: rgb(255, 255, 255);">	</span></span>NativeProcess在windows下只能調用exe</span>, 所以，直接把.bat的路徑傳入nativeProcess的參數中肯定不行。解決方案是用NativeProcess調用cmd.exe，然後將bat的路徑以參數傳入cmd.exe。這樣就可以通過cmd來執行bat了。

<span style="white-space:pre">	</span><span style="font-weight: normal;">var batFile:File = new File();
        NativeApplication.nativeApplication.autoExit = true;
        batFile = batFile.resolvePath("C:/Windows/System32/cmd.exe");
        var batPath:String = File.applicationDirectory.nativePath + "\\mybat.bat";
        var process:NativeProcess = new NativeProcess();
        var processArg:Vector.<String> = new Vector.<String>();
        processArg[0] = "/c";/加上/c，是cmd的參數
        processArg[1] = batPath;
        processArg[2] = "%1";//參數1，傳入cmd內
        var info:NativeProcessStartupInfo = new NativeProcessStartupInfo();
        info.executable = batFile;
        info.arguments = processArg;
        process.addEventListener(NativeProcessExitEvent.EXIT, onExit);
        process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, outputHandlers);
        process.start(info);</span></span>

4.調用browsfor文件或文件夾時，默認定位到剪貼板位置

<span style="font-weight: normal;"><span style="white-space:pre">	</span>var msg:String = Clipboard.generalClipboard.getData(ClipboardFormats.TEXT_FORMAT) as String;
        var f:File = new File();
        try {
            f.nativePath = msg;
        } catch (evt:ArgumentError) {
            trace("參數不合法");
        }</span>
