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.

Only an extension would be able to run code that needs chrome privileges.
