Internet explorer PowerShell-IE对象，设置值时出错

我有一个简单的问题和答案，来源如下：

  <label for="question1" data-role="question-label">
    1. What&#39;s going well? Any wins (big or little) this week?
</label>
<div class="row answer-list">
    <div class="col-xs-12 col-sm-12">



        <div class="row" data-role="answer-box-item">
            <div class="col-xs-12 col-sm-9" data-role="answer-box-content-wrapper">
                <span class="edit-textile-notifications">
                    <span class="glyphicon glyphicon-ok ok-status"></span>
                    <span class="not-sent-answer hidden" data-style="zoom-out">not sent</span>
                </span>
                <p type="text" class="edit-textile form-control input-sm answer-box-content" placeholder="create new answer" data-answer="true" data-question-id="1" data-role="new-answer-form"></p>

            </div>
            <div class="col-xs-12 col-sm-3 answer-actions-wrapper" style="display: none;">
                <div class="btn-group btn-group-sm answer-actions" >
                    <button type="button" class="btn btn-default answer-delete ladda-button" title="remove answer" data-style="zoom-out">
                        <span class="ladda-label">
                            <span class="glyphicon glyphicon-remove"></span>
                        </span>
                    </button>

请你看一下，检查一下我做错了什么，并更正我的代码。我不是高端powershell的家伙：

在尝试获取元素之前，您应该添加这一行，以确保数据已完全加载到$ie下方。导航：

while($ie.ReadyState -ne 4) {start-sleep -m 100}  

这对我来说很有用：while$ie.Busy{start sleep-m 100}

while($ie.ReadyState -ne 4) {start-sleep -m 100}
