我在网页上有一个按钮列表。我可以使用GET类名称功能获取按钮列表。但是我无法迭代它。
这是代码：
main role="main">
<div class="wrapper">
</div>
<div class="wrapper wrapper-medium">
<header>
<h1>Unsubmitted Timesheets</h1>
<div class="clearfix">
<div class="fl-left">
<select name="" id="select-timeframe" class="hui-input"><option value="/missing_time/period/36/2018">05 Feb 2018 - 11 Feb 2018</option>
<option selected="selected" value="/missing_time/period/29/2018">This Week</option>
<option value="/missing_time/period/22/2018">22 Jan 2018 - 28 Jan 2018</option>
<option value="/missing_time/period/15/2018">15 Jan 2018 - 21 Jan 2018</option>
<option value="/missing_time/period/8/2018">08 Jan 2018 - 14 Jan 2018</option>
<option value="/missing_time/period/29/2018?all_weeks=1">- show all weeks -</option></select>

<td>理想情况下，我想单击一个按钮到下一页执行一些操作，然后返回第一页。然后获取下一个按钮。应重复此操作，直到访问所有按钮。我一直在四处张望，但我无法提出解决方案。
我尝试这样做，但它仅针对第一个或最后一个按钮
($ie.Document.GetElementsByClassName("hui-button hui-button-tiny") |
Select-Object -First 1).Click()
($ie.Document.GetElementsByClassName("hui-button hui-button-tiny") |
Select-Object -Last 1).Click()
如果我做这样的事情 -
$ViewTimessheetObject=($ie.document.getElementsByClassName("hui-button hui-button-tiny") |Select-Object -first 1)
while($ie.Busy) { Start-Sleep -Milliseconds 100 }
($ViewTimesheetObject | ForEach-Object {$_.Click()})
它传达了一条错误消息，说"您不能在null值表达式上调用方法。
对此事的任何帮助将不胜感激。
您的foreach应该适用于 $ie.document.getElementsByClassName
($ie.document.getElementsByClassName("hui-button hui-button-tiny")) | Foreach { $_.Click()}
