如何使用Python硒从不在page_source上的网页访问文本？

Question

这是运行javascript的html代码的一部分。我正在尝试访问此脚本的文本。当我执行“检查元素”时，可以看到所需的文本。但是，当我去查看页面源代码或driver.page_source时，它不存在-仅存在此javascript。是否有办法以某种方式运行此javascript，以便我可以抓取它在网页上显示的文本？

以下是在page_source中未显示的Inspect Element代码。我正在尝试访问粗体文本：

<table id="invoiceHistoryTable" class="display dataTable no-footer" cellspacing="0" width="100%" role="grid" aria-describedby="invoiceHistoryTable_info">
        		
<tbody>
<tr role="row" class="odd">
<td class="sorting_1">**4/11/2019 04:12:43 PM**</td><td>291321</td><td>- -</td><td>**Invoice uploaded from file=93564LedesInvoiceAnsi.txt.**</td>
</tr>
<tr role="row" class="even">
<td class="sorting_1">**4/11/2019 04:19:57 PM**</td><td>291321</td><td>- -</td><td>**Client retrieved invoice for processing.**</td>
</tr>
<tr role="row" class="odd">
<td class="sorting_1">**4/17/2019 04:05:19 PM**</td><td>291321</td><td>- -</td><td>**Invoice approved.**</td></tr>
</tbody>
<thead>
            <tr role="row"><th id="header0" class="sorting_asc" tabindex="0" aria-controls="invoiceHistoryTable" rowspan="1" colspan="1" data-column-index="0" aria-label="Date: activate to sort column descending" aria-sort="ascending">Date</th><th id="header1" class="sorting_disabled" rowspan="1" colspan="1" data-column-index="1" aria-label="Invoice No">Invoice No</th><th id="header2" class="sorting_disabled" rowspan="1" colspan="1" data-column-index="2" aria-label="User">User</th><th id="header3" class="sorting_disabled" rowspan="1" colspan="1" data-column-index="3" aria-label="Description">Description</th></tr>
		</thead></table>

这是page_source和javascript代码：

<div class="roundedBoxContent">
    <table id="invoiceHistoryTable" class="display" cellspacing="0" width="100%">
        <thead>
            <tr>
            	<th id="header0">Date</th>
             	<th id="header1">Invoice No</th>
             	<th id="header2">User</th>
             	<th id="header3">Description</th>
             	
            </tr>
		</thead>		
	</table>
</div>



<script type="text/javascript">
	jQuery(function() {
		setupDatePicker("dateStart", "dateEnd");
	});
	
	setCurrentPageSizeInDropdown();
	
	var parameters= {"vendorId" : "379863141", "uniqueId" : "6cebf4f4340ccb1f9efcfafab51e28ea", "role" : "6",
		"buttonText" : {
			"defaultViewButtonText" : "Default View",
			"doneButtonText" : "Done"
		},
		"clearButton" : {
			"buttonId" 		: "clear",
			"formId" 		: "searchForm",
			"filtersClass"	: "filters",
			"tableId"		: "invoiceHistoryTable"
		},"tooltips" : {
			"showHideTooltip" : "Show/Hide Columns",
			"exportExcelTooltip" : "Export to Excel",
			"exportPdfTooltip" : "Export to PDF",
			"printTooltip" : "Print",
			"viewEditTooltip" : "",
			"viewTooltip" : ""
		}
	};
	
    jQuery(".chosen-select").chosen({
    	width: "20%"
    });
    
	

	
		invoiceHistoryTable.loadVendorLevelTable(parameters);
	
</script>
