Assuming to be placed in a variable, because you have 'json' tagged. The following is some explanation of each step of a simple example breakdown:
假设被放置在一个变量中,因为你有 'json' 标记。以下是对简单示例细分的每个步骤的一些解释:
// create an empty array
var array = [];
// create an object with properties "id", "action" with mock values
var object = {
  id: "1",
  action: "shout" 
}
// add object to array
array.push(object);
// create encode json string
var myJSONString = JSON.stringify(array);
Hope this helps.
希望这可以帮助。
