Question

在第二次运行此脚本时，如果我第一次关闭Bing，我可以打开Microsoft和Yahoo;如何在不先关闭Bing的情况下打开这些网站？错误：

Method invocation failed because [System.Object[]] doesn't contain a method named 'Navigate2'.
+                 $ie.Navigate2 <<<< ("www.microsoft.com", $navOpenInNewTab);
+ CategoryInfo          : InvalidOperation: (Navigate2:String) [], Runtime Exception
+ FullyQualifiedErrorId : MethodNotFound

为什么Bing和Google打开时会失败，但是当我打开Google时却没有？

# Set BrowserNavConstants to open URL in new tab

$ie = $null

        $ie.Navigate2("www.yahoo.com", $navOpenInBackgroundTab); break
    }
    default {
        $google = $false
        # Check if Google open
        foreach ($tab in $ie) {
            if ($tab.LocationURL.Contains("google"))
            { $google = $true; break }
        }
        # If Google open on second run, open Microsoft and Yahoo
        if ($google) {
            $ie.Navigate2("www.microsoft.com", $navOpenInNewTab);
            $ie.Navigate2("www.yahoo.com", $navOpenInBackgroundTab);
        } else {
            # On first run, open Bing and Google 
            $ie.Navigate("www.bing.com");
            $ie.Navigate2("www.google.com", $navOpenInBackgroundTab);
        }
        break
    }
}

# Cleanup

您的问题似乎是，脚本无法在第二次运行时找到（右侧）打开的IE实例。在PowerShell ISE（或PowerShell PowerGUI）中调试脚本，并在$ie=(New-Object -COM "Shell.Application").Windows() | ? {$_.Name -eq "Internet Explorer"}

设置断点

在下面的交互式PowerShell窗口中运行以下命令：(New-Object -COM "Shell.Application").Windows() | Select-Object { $_.Name }

你得到这样的东西作为输出吗？

File Explorer    
Internet Explorer  
Internet Explorer  
Internet Explorer  
Internet Explorer

当IE窗口具有不同的名称时，尝试根据需要调整代码以下代码适用于我的机器：我只选择第一个IE实例（否则您打开多个站点时会出现问题）。

    ...
    # If Google open on second run, open Microsoft and Yahoo
    if ($google) {
        sleep -milliseconds 50
        $ie[0].Navigate2("www.microsoft.com", $navOpenInBackgroundTab);
        sleep -milliseconds 50
        $ie[0].Navigate2("www.yahoo.com", $navOpenInBackgroundTab);
    } else { ...

如果使用PowerShell打开另一个URL，则在IE中打开一组URL
