Access the website in a simple way

Using IE's COM object to complete a simple Web automation test is the most compact and inexpensive Web automation test since it does not have to introduce third-party plug-ins or tools. The Windows system comes with the Internet explorer and PowerShell.

Start-Process -FilePath iexplore

• FilePath:Open the process by its file path
• By default.the powershell will open Internet Explorer and ignore the default browser.And it will always open a new monitor of the browser

Start-Process -FilePath iexplore -ArgumentList www.baidu.com

• ArgumentList:Add the parameters to the process.In this ,parameter is the url which to be access

Start-Process -FilePath www.baidu.com

• FilePath :Directly add a parameter to the powershell,which means open a new tag to access the website while you have open your default browser.
• This is different from the last operation

Open browser to view the website as well as searching something

Create a browser object

$ie = new-object -com "InternetExplorer.Application";
$ie.navigate("www.baidu.com");
$ie.Visible=$true;

• new-object : Create a new COM object "IE explorer"
• navigate : View the website
• Visible :Only the value of the parameter "Visible" is true can we see a real time operation on the monitor .Or ,it will go on everything in the background which we can not see it.

Locate the element of the website

$inputs=$ie.Document.getElementsByName('wd')

• getElementsByName :Get the element by the HTML tag name

Input something to search

foreach($element in $inputs){
    $element.value="who is cha0s0000"
 }

• value:Sent a value to the HTML tag of input,which will lead to the baidu search engine

Start to search

$inputs=$ie.Document.getElementById('su').click()

• getElementById :Get the "search "button by its HTML ID
• click() :Simulate the mouse click

The whole program

function IEexplorer($url)
{
    $ie = new-object -com "InternetExplorer.Application";
    $ie.navigate($url);
    $ie.Visible=$true;
    [System.Threading.Thread]::Sleep(2000);
    return $ie;
}
$ie = IEexplorer('www.baidu.com')
$inputs=$ie.Document.getElementsByName('wd')
foreach($element in $inputs){
$element.value="steemit cha0s0000"
 }
$inputs=$ie.Document.getElementById('su').click()
