我试图填补了我的用户名和密码的特定网页，然后在preSS的登录按钮，所有这些都通过PowerShell的自动完成。

问题是，我无法找到在HTML源$ C ​​$ c中的登录按钮的ID。

我曾尝试使用下面的命令：

但是这并没有任何工作。

其中任何一个PS命令来使用，如果我想preSS的登录按钮？想法

解决方案

作为@杰米 - 泰勒提到的登录按钮其实是在一个按钮。

您不仅可以通过该ID，但也可以通过使用类名 document.documentElement.getElementsByClassName 访问它。请注意这个函数会返回元素的列表，页面上有一个元素可以有相同的类。

修改
我错了：为了有 getElementsByClassName 你要调用它 document.documentElement中而不是文件

I'm trying to fill in my username and password on a certain web page and then the press the "sign-in" button, all automatically via Powershell.

The problem is that I cannot find the ID of the sign-in button in the html source code.

I have tried to use the command:

$link = $ie.Document.getElementsByTagName('A') | where-object {$_.innerText -match 'sign in'}

but this didn't worked either.

Any thoughts which PS command to use if I want to press the 'sign in' button?

The HTML code is as follows:

<div class="login">
    <div class="content">
        <div class="subsection-1">Sign in or create a <a id="ctl00_HeaderUserControl_LoginUserControl_hypNewAccount" href="/authentication/registerprovider.aspx?">new account</a></div>
        <div class="subsection-2">
            <span class="navy bold">What is your email address?</span>
            <div class="indent">
                <span class="bold">Email:</span>
                <input id="loginEmail" class="text-box" type="text" maxlength="100" tabindex="1" />
                <img class="ajax-loader" src="/content/images/research/global/transparent.gif" alt="" />
            </div>
            <div class="invalid-email"></div>
        </div>
        <div class="subsection-3">
            <span class="navy bold">Do you know your password?</span>
            <div>
                <input id="passwordNotKnown" name="passwordSwitch" type="radio" checked="checked" />
                <label for="noPassword">No, I don't know my password or I'm new .</label>
            </div>
            <div>
                <input id="passwordKnown" name="passwordSwitch" type="radio" />
                <label for="noPassword">Yes, my password is:</label>
                <input id="loginPassword" class="text-box" type="password" maxlength="50" tabindex="2" />
            </div>
            <div class="invalid-password"></div>
            <div class="error"></div>
        </div>
        <div class="subsection-4">
            <button type="button" class="login-button greenButton" tabindex="4">Sign in</button>
            <a href="javascript:void(0);" class="cancel-link">Cancel</a>
            <input id="stayLoggedIn" type="checkbox" tabindex="3" />
            <label for="stayLoggedIn">Stay signed in</label>
        </div>
    </div>
    <div class="reset-password">
        <div class="subsection-1">Would you like to reset your password?</div>
        <div class="subsection-2">Choosing <span class="bold">yes</span> will reset your password and email a temporary password to: <span class="repeat-email"></span></div>
        <div class="subsection-3">
            <div class="center">
                <button class="reset-password-button" type="button">Yes</button>
                <button class="do-not-reset-password-button" type="button">No</button>
            </div>
        </div>
    </div>
</div>

解决方案

As @Jamie-Taylor mentioned the login button is in fact a button.

You can access it not only by the id but also by the class name using document.documentElement.getElementsByClassName. Please notice this function will return list of elements as more than one element on page can have the same class.

EDIT I was wrong: in order to have getElementsByClassName you have to call it on document.documentElement instead of document
