【问题描述】：
我正在尝试使用 selenium 自动化网站以下载 excel 文件。 我有以下 HTML 按钮：
<div class="row ng-scope" ng-if="!model.update_rota">
<div class="col-sm-12 hidden-xs hidden-sm">
<button type="button" class="btn btn-success btn-block" title="יצא לאקסל" ng-click="excelRota();" ng-disabled="!model.rota.id || model.rotaLoading">
<i class="fa fa-file-excel-o fa-lg"></i> אקסל
</button>
</div>
<!-- ngIf: model.features.reports.attributes.availability_shifts_report.value == 'True' -->
<!-- ngIf: model.features.tips.is_active && model.features.tips.attributes.tips_calculate.value == 'True' -->
<div class="col-sm-12">
<div class="btn-group btn-block visible-xs-block visible-sm-block">
<button type="button" class="btn btn-info btn-block dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" ng-disabled="model.rotaLoading">
<i class="fa fa-bars fa-lg"></i> אפשרויות
</button>
<ul class="dropdown-menu">
<!-- ngIf: model.features.tips.is_active && model.features.tips.attributes.tips_calculate.value == 'True' -->
<li ng-class="{'disabled': !model.rota.id}" class="" style=""><a href="#" ng-click="excelRota();"><i class="fa fa-file-excel-o text-success"></i> יצא סידור לאקסל</a></li>
<!-- ngIf: model.features.reports.attributes.availability_shifts_report.value == 'True' -->
</ul>
</div>
</div>
</div>
我已尝试按类单击具有以下查找元素的按钮：
driver.find_element_by_class_name('btn btn-success btn-block').click()
我得到的错误信息是：
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".btn btn-success btn-block"}
我也试过了：
driver.execute_script("excelRota();")
并收到以下错误：
selenium.common.exceptions.JavascriptException: Message: javascript error: excelRota is not defined
我已成功登录该网站并在该网站上工作，直到出现 excel 文件页面，但我不知道如何单击此按钮。
如果有任何区别，我已将脚本编写为 headless chrome。
更新：
这是我的全部代码：
