用Web Driver開啟網頁

上一篇有說過，不同瀏覽器會有不同的Web Driver，本篇以Chrome作範例

用其他瀏覽器的請左轉別的教學喔 ><

切記Web Driver一定要和selenium和python放在同一個執行目錄底下，不然程式執行會找不到喔!

以下是有正確放在同一目錄執行的程式碼:

from selenium import webdriver #叫出同一目錄的selenium和web driver

driver = webdriver.Chrome() #指定此web driver是chrome版本的

driver.get("https://www.google.com/?hl=zh_tw") #前往這個網址

driver.close() #關閉視窗

執行到第二行的時候，web driver會另外開啟一個瀏覽器視窗，視窗上會出現

「Chrome 目前受到測試軟體控制」，表示web driver已經透過程式控制瀏覽器囉!

在第三行，使用driver.get()讓web driver打開google頁面

最後一行，使用driver.close()關閉整個瀏覽器視窗，到這裡就學會自動開啟網頁的部分了!

Selenium定位元素

Emphasis

Emphasis, aka italics, with asterisks or underscores.

Strong emphasis, aka bold, with asterisks or underscores.

Combined emphasis with asterisks and underscores.

Strikethrough uses two tildes. Scratch this.

Link

I’m an inline-style link

I’m an inline-style link with title

I’m a reference-style link

I’m a relative reference to a repository file

You can use numbers for reference-style link definitions

Or leave it empty and use the link text itself.

URLs and URLs in angle brackets will automatically get turned into links. http://www.example.com or http://www.example.com and sometimes example.com (but not on Github, for example).

Some text to show that the reference links can follow later.

Code and Syntax Highlighting

Inline code has back-ticks around it.

var s = "JavaScript syntax highlighting";
alert(s);

s = "Python syntax highlighting"
print s

No language indicated, so no syntax highlighting. 
But let's throw in a <b>tag</b>.

Blockquote

This is a blockquote example.

Inline HTML

You can also use raw HTML in your Markdown, and it’ll mostly work pretty well.

Tables

Colons can be used to align columns.

There must be at least 3 dashes separating each header cell. The outer pipes (|) are optional, and you don’t need to make the raw Markdown line up prettily. You can also use inline Markdown.
