Question

我填写了一个网站以登录并输入号码。多数民众赞成在似乎工作，但我不能以某种方式执行事件按钮。也许很简单，但是我无法从.NET中的代码中单击它。

在.NET

Web.Document.GetElementById("hwbOrPiece").InnerText = txtCID.Text
Web.Document.InvokeScript("query()")

网站

<button class="md-icon-button md-button md-ink-ripple" type="button"
        ng-transclude="" aria-label="Search" ng-click="query()">

    <i class="material-icons md-24 ng-scope">search</i>
</button>

<button class="md-icon-button md-button md-ink-ripple" type="button"
        ng-transclude="" aria-label="Search" ng-click="query()">

    <i class="material-icons md-24 ng-scope">search</i>
</button>

输入字段“ hwbOrPiece”有效，我看到了该值。手动地，我按下搜索按钮，我得到了结果。但是，当然，我想使其自动化。所以我希望事件'query（）'在我的代码中执行。

一些帮助会很棒！

亲切的问候，克里斯

（当然）尝试并查看了很多信息之后，我可以触发按钮：

    Dim HtmlElementcol As HtmlElementCollection = Web.Document.GetElementsByTagName("button")
    For Each ele As HtmlElement In HtmlElementcol
        'Check the attributtes you want
        If ele.InnerText = "search " Then 'The space must be there
            ele.InvokeMember("click")
        End If
    Next

但是我的下一个问题是，单击按钮后找不到该值。我想我必须将角度值更新为？

HTML代码：

                <input type="text" ng-model="hwbOrPiece" ng-trim="true" awb-or-piece="" md-no-asterisk="" name="hwbOrPiece" id="hwbOrPiece" maxlength="35" ng-keyup="$event.keyCode == 13 &amp;&amp; query()" class="ng-valid md-input ng-valid-response-validator ng-valid-maxlength ng-not-empty ng-dirty ng-valid-awb-validator ng-valid-srk-validator ng-valid-piece-validator ng-valid-parse ng-touched" aria-invalid="false" style=""><div class="md-errors-spacer"></div>
