您的情况可以通过以下方式获得 myParam 的值：

  var target = grunt.option（'myParam'）; 
 

I have a Grunt build file. My build file has a task that looks like the following:

myTask: {
  options: {
    configFile: "config/default.js",
    args: {   }
  },
  dev: {
    configFile: 'config/local.js',
    options: { args: {} },
  },
  test: {
    configFile: 'config/remote.js',
    options: { args: {} }
  }
}

...

grunt.registerTask('customTask', ['myTask:dev']);
grunt.registerTask('customTask-Test', ['myTask:test']);

Currently, I can run the following from the command line:

> grunt customTask

Everything works fine. However, I need to add the ability to do something like this:

> grunt customTask --myParam=myValue

I need to look at the value of myParam in my "dev" task target. However, I can't figure out how to do it. I would be happy if I could just print out the value of myParam when myTask:dev is ran. In other words, I'd like to see the following when run

> grunt customTask

> grunt customTask --myParam=hello
You entered hello

> grunt customTask-Test

> grunt customTask-Test --myParam=hello

How do I do something like this?

This is all explained in the grunt.option page.

In your case, you could get the value of myParam with:

var target = grunt.option('myParam');
