TPS History Lists 编辑

There are two types of history asset lists, one used for adding/modiyfing/verifying history, and the other for deleting history.

The history list used for operations other than delete has the following properties:

• uri: required.
• title: optional. The page title for this uri.
• visits: required. An array of objects representing visits to the page, each object has the following properties:
  • type: required. An integer value from one of the transition types listed at /wiki/en/nsINavHistoryService#Constants.
  • date: required. An integer representing when the visit took place, expressed in hours from the present. For example, 0 is now, -24 is 24 hours in the past.

For example:

var history_initial = [
  { uri: "http://www.google.com/",
    title: "Google",
    visits: [
      { type: 1, date: 0 },
      { type: 2, date: -1 }
    ]
  },
  { uri: "http://www.cnn.com/",
    title: "CNN",
    visits: [
      { type: 1, date: -1 },
      { type: 2, date: -36 }
    ]
  },
];

The history list used for deletions looks different. It's an array of objects, each of which represents a type of history to delete. There are three different types:

• to delete all references to a specific page from history, use an object with a uri property
• to delete all references to all pages from a specific host, use an object with a host property
• to delete all history in a certain time period, use an object with begin and end properties, which should have integer values that express time since the present in hours (see date above)

For example:

var history_to_delete = [
  { uri: "http://www.cnn.com/" },
  { begin: -24,
    end: -1 },
  { host: "www.google.com" }
];
