前段时间公司要求调研了插件开发，现在做一些总结。
功能1：通过Chrome插件获取浏览器的书签。
要在扩展中操作书签，需要在Manifest中声明bookmarks权限：
"permissions": [
"bookmarks"
]
以下是获取用户完整书签的方法
chrome.bookmarks.getTree(function(bookmarkArray){
console.log(bookmarkArray);
});
下图是通过getTree方法获取的完整的Chrome浏览器书签结构。

]以下是解析该书签结构的方法：需求是需要获取每个书签的url以及这个书签的完整路径。
function analyseBookMark (data, bookmarkArray, path) {
for (var children in data) {
if (data[children].length > 0 && typeof(data[children]) == "object") {
if (data && data.title && data.title !== '') {
path = path + data.title + '/';
}
analyseBookMark(data[children], bookmarkArray, path);
} else {
if (typeof(data[children]) == "object") {
for(var childKey in data[children]) {
if (typeof(data[children][childKey]) == "object") {
if (data && data[children].title && data[children].title !== '') {
path = path + data[children].title + '/';
}
analyseBookMark(data[children][childKey], bookmarkArray, path);
} else {
if (childKey === "url") {
var url = data[children][childKey];
var title = data[children].title;
var path = path;
var jsonData = {
title: title,
url: url,
path: path
};
bookmarkArray.push(jsonData);
}
}
}
} else {
if (children === "url") {
var url = data[children];
var title = data.title;
var path = path;
var jsonData = {
title: title,
url: url,
path: path
};
bookmarkArray.push(jsonData);
}
}
}
}
};
