AngularJS利用Html5Mode去掉地址栏#

浏览$location的实例代码我们不难发现，每次的url中都会带一个#,这是因为angularjs默认使用的是标签模式，它和html5模式有什么区别？

标签模式

标签模式使用的是内部链接的技巧，URL后面紧跟一个#,angularjs本身不会重写标签，也不需要服务器端的支持，链接后的URL样子基本是这样的：

http://example.com/#/some/path?foo=bar&baz=xoxo

HTML5模式

标签模式的url看起来总是觉得不爽，html5模式可能比较适合咱们的请求格式(比如说REST),

http://example.com/some/path?foo=bar&baz=xoxo

在angularjs内部，可以通过$locationProvider.Html5Mode()(内部用的是html5 history api,如果浏览器不支持将自动降级到标签模式)方法来实现这样的路由要求，在该模式下，angularjs会重写标签。使用该模式时，永远都不要使用相对路径，如果你的应用是在根路径中加载的,这不会有什么问题,但如果是在其他路径中,AngularJS应用就无法正确处理路由了. 为了在应用程序各处使用相对链接，你将需要在你文档的里面设置一个.

html5 history api

history.pushState(data, title [, url])：往历史记录堆栈顶部添加一条记录；data会在onpopstate事件触发时作为参数传递过去；title为页面标题，当前所有浏览器都会忽略此参数；url为页面地址，可选，缺省为当前页地址。

history.replaceState(data, title [, url]) ：更改当前的历史记录，参数同上。

history.state：用于存储以上方法的data数据，不同浏览器的读写权限不一样。

浏览器支持情况(完整的可以通过www.caniuse.com查询)

IE 10+, FF38+,chrome 31+,safari 7.1+, opera 30+

为什么要用history api?

无法使用浏览器的前进、后退来切换前后数据。
当我们将浏览器地址栏中的链接与朋友分享时，可能实际上却并非我们期望的内容。
单纯地使用AJAX不利于搜索引擎优化。

alien:deb(ubuntu/debian)与rpm(centos/fedora)转换工具

deb 与 rpm 是GNU/Linux 流行的软件包格式。我们“alien”可以在rpm\dpkg\slackware tgz\deb\slp 格式见进行转换。

Debian/Ubuntu 可使用下面命令安装alien：

sudo apt-get install alien

从RPM转到DEB

举例：假设在目录/tmp 有myprogram.rpm 文件，使用下面命令转换：

sudo alien /tmp/myprogram-1.10-2.i386.rpm

myprogram-1.10-3.i386.deb generated

这时，在/tmp 目录下就会发现有 myprogram.deb ，这时就可以使用dpkg安装：

dpkg -i /tmp/miprogramma.deb

从DEB转到RPM

直接添加参数-r进行转换即可：

sudo alien -r pytube_0.0.8.1-1_all.deb

pytube-0.0.8.1-2.noarch.rpm generated

yii2 实现tree grid

yii2-gtreetable

Extension of Yii 2 Framework, which is wrapper for bootstrap-gtreetable plugin, on the other hand it provides functionality which allows to save the nodes states into database. http://gtreetable2.gilek.net

yii2-nested-sets

The nested sets behavior for the Yii framework.

yii2-treegrid

jQuery TreeGrid Extension for Yii 2

This is the jQuery TreeGrid extension for Yii 2. It encapsulates TreeGrid component in terms of Yii widgets, and thus makes using TreeGrid component in Yii applications extremely easy.

tree-manager

An enhanced tree management module from Krajee with inbuilt jQuery plugins and Yii widgets for tree node manipulation and management using nested sets. The module provides ability to manage hierarchical data stored using nested sets. It utilizes the yii2-nested-sets extension to manage the tree structure in your database. Refer the documentation for yii2-nested-sets extension before you start using this module. The yii2-tree-manager module includes two major widgets TreeView and TreeViewInput. In addition, it includes module level settings to easily configure your tree management preferences. It includes a Tree Model which includes inbuilt tree management flags and rules. The model implements and uses a TreeTrait. So one can choose to extend from the Tree Model or implement their own model that uses the TreeTrait. It also includes a NodeController that allows you to manage tree nodes easily via ajax. The tree view widgets and jQuery plugins are built from scratch by Krajee entirely without using any third party plugins. The TreeView is designed using HTML5, jQuery & CSS3 features to work along with the Yii 2 framework.
