如何从Firefox插件打开外部应用程序? (例如:默认的文本编辑器) [英] How can I open an external app from Firefox addon? (Eg: default text editor)
问题描述
这段代码在提供路径时显示或启动一个文件:
var localFile = Cc [@ mozilla.org/file/local;1\"].createInstance(Ci.nsILocalFile);
localFile.initWithPath(C:\\some-directory\\some-file.png);
if(localFile.exists()){
// localFile.reveal(); //打开文件的包含文件夹
// localFile.launch(); //启动文件
}
然而,您可能需要使用 nsIProcess ,以便运行一个带有参数的可执行文件(例如你正试图用可执行文件打开的文件路径)。
var exeFile = Cc [@ mozilla.org/file/local;1\"].createInstance(Ci.nsILocalFile);
exeFile.initWithPath(C:\\Program Files\\ ... \\app.exe);
var parameter =C:\\some-directory\\some-file.txt;
if(exeFile.exists()){
var process = Cc [@ mozilla.org/process/util;1\"].createInstance(Ci.nsIProcess);
process.init(exeFile);
process.run(false,[parameter],1); //以另一个文件为参数启动可执行文件。

I need my addon will be capable of editing some files with an external tool. Any ideas?
解决方案 This snippet reveals or launches a file when provided with a path:
var localFile = Cc["@mozilla.org/file/local;1"].createInstance(Ci.nsILocalFile);
localFile.initWithPath("C:\\some-directory\\some-file.png");
if(localFile.exists()){
// localFile.reveal(); // open the containing folder of the file
// localFile.launch(); // launch the file
}
However you might need to use nsIProcess in order to run an executable with parameters (such as the filepath you're trying to open with the executable).
var exeFile = Cc["@mozilla.org/file/local;1"].createInstance(Ci.nsILocalFile);
exeFile.initWithPath("C:\\Program Files\\...\\app.exe");
var parameter="C:\\some-directory\\some-file.txt";
if(exeFile.exists()){
var process = Cc["@mozilla.org/process/util;1"].createInstance(Ci.nsIProcess);
process.init(exeFile);
process.run(false,[parameter],1); // launch the executable with another file as parameter.
}
