Question

我正在尝试使用Excel文件中的信息来自动化IE中的某些任务。我对VBA的了解可以使我在网站上以“是”回答问题，这将打开另一个具有更多选择项的问题。正如我所说的，第一个是，但是另一个问题没有出现。

以下是网站上JavaScript代码的一部分和HTML代码的一部分：

    var elemData = jQuery.data( elem );

    // If no elemData is found then we must be trying to bind to one of the
    // banned noData elements
    if ( !elemData ) {
        return;
    }

    var events = elemData.events = elemData.events || {},
        eventHandle = elemData.handle, eventHandle;

    if ( !eventHandle ) {
        elemData.handle = eventHandle = function() {
            // Handle the second event of a trigger and when
            // an event is called after a page has unloaded
            return typeof jQuery !== "undefined" && !jQuery.event.triggered ?
                jQuery.event.handle.apply( eventHandle.elem, arguments ) :
                undefined;
        };

<p>
	<span class="i_lbReq">First question</span> //this line has the 'change: eventHandle' event/function associated to it
    <br></br>
	<select name="meetingQuestionAnswer(220674)" class="auto-save">
    <option value=""> --- --- </option>
    <option value="Yes" selected="">Yes</option>
    <option value="No">No</option>
    <option value="Pending">Pending</option>
    </select>
 </p>
<div class="recursive-question" id="meetingDependentQuestion(220674)"> //this line has the 'change: eventHandle' event/function associated to it
<div id="meetingQuestionAnswerDiv(221010)">
    	<input name="meetingQuestionValidatorRule(221010)" type="hidden" value="">
      <input name="meetingQuestionReadOnly(221010)" type="hidden" value="">
      <p>
	<span class="i_lb">Dependent question 1</span>
        <br></br>
        <select name="meetingQuestionAnswer(221010)" class="auto-save">
        <option value="" selected=""> --- --- </option>
        <option value="Yes">Yes</option>
        <option value="No">No</option>
        </select>
      </p>
	<div class="recursive-question" id="meetingDependentQuestion(221010)">
        <div id="meetingQuestionAnswerDiv(221011)">
    	  <input name="meetingQuestionValidatorRule(221011)" type="hidden" value="">
          <input name="meetingQuestionReadOnly(221011)" type="hidden" value="">
          <p>
            <span class="i_lb">Dependent question 2</span>
            <br></br>
            <select name="meetingQuestionAnswer(221011)" class="auto-save">
            <option value="" selected=""> --- --- </option>
            <option value="Yes">Yes</option>
            <option value="No">No</option>
            </select>
          </p>
			<div class="recursive-question" id="meetingDependentQuestion(221011)">

		</div>
   </div>
  </div>
 </div>

我已尝试使用VBA在第一个问题元素上使用方法.FireEvent“ onchange”，但此方法不起作用

Dim ieApp As SHDocVw.InternetExplorer
Set ieApp = IEWindowFromTitle("Profile Form Detail View")
If Not ieApp Is Nothing Then
    Set ieDoc = ieApp.document
End If


For Each cell In GMF.Sheets("BUDGET").Range("B4:B" & Cells(Rows.count, 2).End(xlUp).Row)
    If cell.Value = "MRR" Then
        ieDoc.getElementsByName("meetingQuestionAnswer(220674)")(0).Value = "Yes" 'this works fine
        ieDoc.getElementsByName("meetingQuestionAnswer(220674)")(0).FireEvent "onchange" 
        ieDoc.getElementsByName("meetingQuestionAnswerDiv(221010)")(0).Value = "Yes" 'this one never appears after saying yes in the previous question
    End If
Next cell

尝试参考下面的代码示例可能有助于解决您的问题。

Dim event_onChange As Object 
Set event_onChange = hdoc.createEvent("HTMLEvents") 
event_onChange.initEvent "change", True, False 

vSelect.dispatchEvent event_onChange

参考：

Vba, HTMLSelect: FireEvent OnChange or DispatchEvent
