extension components to get visit count in firefox

问题:

I'd like to to know which interface can be used to get the visit count of each link in firefox's bookmarks and history for developing an extension

I've tried using nav-history-service to get the links for bookmarks and history but can't figure out how to view the visit count.

This code here will go through the first 10 bookmark entires. If it's a url it checks its .accessCount property which holds the number of times it was visited.

var hs = Cc["@mozilla.org/browser/nav-history-service;1"].getService(Ci.nsINavHistoryService);

var query = hs.getNewQuery();
var options = hs.getNewQueryOptions();

// Query users bookmarks, not history
options.queryType = options.QUERY_TYPE_BOOKMARKS;
// Execute the search and store results
var result = hs.executeQuery(query, options);

// Open the root containerNode and open it
var resultContainerNode = result.root;
// OPEN resultContainerNode
resultContainerNode.containerOpen = true;
// Search results are now child items of this container?
for (var i = 0; i < resultContainerNode.childCount; ++i) {
    var childNode = resultContainerNode.getChild(i);
    if (childNode.type == childNode.RESULT_TYPE_URI) {
        console.log('childNode ' + i + ' is url = ', childNode)
        console.log('times visited = ', childNode.accessCount)
    }
    if (i >= 10) {
        break
    }
}

// CLOSE resultContainerNode
resultContainerNode.containerOpen = false;
