我的java程序中有两个框架。一个用于凭证窗口，另一个用于进度条。当我单击登录按钮时，进度条也应该开始工作。这是我的代码

我正在显示两个帧。但是当我按下登录按钮时，我没有让进度条运行。而且我无法将用户名和密码字段的值输入到powershell脚本中。我的powershell代码在stage1.ps1下面给出：
$username = $env:USER
$password = $env:PASS
$url = "https://www.jabong.com/customer/account/login/"
$ie = New-Object -com internetexplorer.application;
$ie.visible = $true;
$ie.navigate($url);
while ($ie.Busy -eq $true)
{
Start-Sleep 1;
}
$ie.Document.getElementById("LoginForm_email").value = $username
$ie.Document.getElementByID("LoginForm_password").value=$password
$ie.Document.getElementByID("qa-login-button").Click();
当我点击登录按钮时会调用网页。但是我没有将挥杆窗口中的凭据值传递给它
