Components.interfaces.nsIProcess 参数带空格会被截断，怎样才能用带空格的参数
写火狐扩展时发现，用Components.interfaces.nsIProcess，调用run函数，可以传入参数数组，但是单个参数内，如果包含空格，会被截断，只留空格前的内容，加双引号也没用，如果我要传的参数是带空格的路径，该如何处理 function hello() {
var oURL = "c:/a/a x";
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
var process = Components.classes['@mozilla.org/process/util;1'].getService(Components.interfaces.nsIProcess);
var targetFile = Components.classes['@mozilla.org/file/local;1'].createInstance(Components.interfaces.nsILocalFile);
targetFile.initWithPath("D:/temp/a e/1.exe");
process.init(targetFile);
var arguments = [oURL];
process.run(false, arguments, arguments.length,{});
}

You can't use such code in current Firefox releases. Support for enablePrivilege stopped long ago, so this is not possible.
- bug 546848 - Remove support for enablePrivilege
Only an extension would be able to run code that needs chrome privileges.
我就是在写扩展的时候发现这个问题的，路径参数数组中，参数带空格会被截断
