我正在尋找一種 Javascript 解決方案，該解決方案將根據在同一表單的其他地方選擇的特定下拉值（在標準 HTML 中，由 SQL 生成）啟用（在其中放置檢查）表單上的復選框。我還沒有寫任何代碼，所以現在沒有任何代碼可以在這里展示。20 年 4 月 8 日編輯：根據 Giuliano 的出色幫助，我決定添加我放在一起的代碼（不起作用），如下所示：<%sSQL = "SELECT OrderTypeID, OrderTypeString FROM LookupOrderTypesII"Set rsOrderTypes = Server.CreateObject("ADODB.RecordSet")rsOrderTypes.Open sSQL, oConnGlobal, adOpenStatic, adLockReadOnly iTotalRecords = rsOrderTypes.RecordcountIf iTotalRecords > 0 Then%><br><b>SERVICE/ORDER TYPE:</b><br><script type="text/javascript">    let select = document.getElementById("cboOrderType");    let checkbox = document.getElementById("chkSkipVenueEventDetails");        select.addEventListener("change", function () {        checkbox.checked = select.value == "12|LABOR SALES/PAYMENT";        });</script><select class="rounded" name="cboOrderType" id="cboOrderType">    <option value="Select One" selected>Select One</option>    <option value="-9999" <%=IfSelected(iOrderTypeID, "Not Listed-ADD Custom Type")%>>Not Listed-ADD Custom Type</option>    <%        Do While Not rsOrderTypes.EOF             iOrderTypeID = Trim(rsOrderTypes("OrderTypeID"))            sOrderTypeString = Trim(rsOrderTypes("OrderTypeString"))    %>        <option value="<%=iOrderTypeID%>|<%=sOrderTypeString%>"<%=IfSelected(sOrderTypeString, sOrderTypeString_NewRequest)%>><%=sOrderTypeString%></option>    <%        rsOrderTypes.MoveNext        Loop    %></select><%     rsOrderTypes.Close    Set rsOrderTypes = NothingEnd If%>'''The SQL code generates the following code (as viewed in browser source):'''</select>這是復選框 HTML：<input type="checkbox" name="chkSkipVenueEventDetails" id="chkSkipVenueEventDetails">&nbsp;<strong>Skip Venue & Event Details</strong>&nbsp;&nbsp;
