click hyperlink using powershell
well, make works in lab.
assuming sample html file :
<html> <body> <script type="text/javascript"> function poweron(){ document.location.href="http://google.com"; } </script> <a href="javascript:onclick=poweron();"><img src="http://www.google.fr/url?source=imglanding&ct=img&q=http://www.picturesnew.com/media/images/e4454c8df9.png&sa=x&ei=lbhpvazqg6a07ga6l4ja&ved=0cakq8wc&usg=afqjcnfnfxiwemexihvyqvfhmmgxofcjfg" width="75" height="32" border="0" name="power_on"></a> </body> </html> then powershell script :
$ie = new-object -com internetexplorer.application $ie.visible=$true $ie.navigate('http://192.168.108.130') $link=$ie.document.getelementsbytagname('a') | where-object {$_.href -eq "javascript:onclick=poweron();"} $link.click() from there, when run powershell script redirected google if clicking on image.
i think main problem has -match expression used. not sure why...but i've used -eq instead.
i've add onclick event in href directive seems required call $link.click().
