Mechanical soup - 填表，工作有技巧HTMLtable
Mechanical soup - form filling, working with a tricky HTML table
我正在尝试使用机械汤自动填充并为我提交时间sheet。
表格如下所示：
timesheet_form
这是页面该部分的相关源代码：

我正在使用机械汤填写表格并提交。
#navigate to the timesheet page
browser.open(timesheetURL)
browser.get_current_page()
#select the form
browser.select_form('form[action="bwpkteci.P_UpdateTimeInOut"]')
form = browser.get_current_form()
#add required controls and set values for testing
form.new_control('text', 'shift', '1')
form.new_control('text', 'TimeIn', '08:30')
form.new_control('select', 'TimeInAm', 1) #1 stands for PM
form.new_control('text', 'TS_TimeOut', '09:30')
form.new_control('select', 'TimeOutAm', 1) #1 stands for PM
form.new_control('submit', 'ButtonSelected', 'Save')
form.choose_submit('ButtonSelected')
browser.launch_browser()
browser.submit_selected()
browser.launch_browser()
我必须使用 new_control 函数添加新控件，因为当我通过启动浏览器进行检查时，TimeIn、TimeOut 框没有显示。
这段代码不起作用，我不明白为什么。我想也许我弄乱了我添加的控件的名称或类型（也许它与表单的实际输入类型和名称不匹配 - 我检查了 chrome 扩展名，那也是不是这种情况）因为保存按钮会被点击但测试值并没有真正注册。

使用 MechancialSoup 版本 0.10.0，我能够正确解析您的 HTML 片段（据我所知）。对于旧版本的 MechanicalSoup，我没有看到任何具体会导致此问题失败的内容，但如果没有其他效果，也许可以尝试更新。
我使用了以下简单代码：
import mechanicalsoup
browser = mechanicalsoup.StatefulBrowser()
browser.open_fake_page(text) #Here 'text' is the HTML snippet
form = browser.select_form('form[action="bwpkteci.P_UpdateTimeInOut"]')
form.print_summary()
browser.launch_browser()
print_summary() 方法输出所有表单元素，其中包括您缺少的 TimeIn 和 TimeOut 框：
<input name="JobsSeqNo" type="hidden" value="208138"/>
<input name="LastDate" type="hidden" value="0"/>
<input name="par_restart" type="hidden" value="Y"/>
<input name="par_update" type="hidden" value="Y"/>
<input name="par_submit" type="hidden" value="Y"/>
<input name="par_recall" type="hidden" value="N"/>
<input name="EarnCode" type="hidden" value="RSA"/>
<input name="DateSelected" type="hidden" value="20-FEB-2018"/>
<input name="LineNumber" type="hidden" value="1"/>
<input id="shift_input_id" maxlength="1" name="Shift" size="2" type="text" value="1"/>
<input id="timein_input_id" maxlength="5" name="TimeIn" size="6" type="text"/>
<select name="TimeInAm" size="1">
<option selected="" value="AM">AM</option><option value="PM">PM</option></select>
<input id="timeout_input_id" maxlength="5" name="TS_TimeOut" size="6" type="text"/>
<select name="TimeOutAm" size="1">
<option selected="" value="AM">AM</option><option value="PM">PM</option></select>
<input name="ButtonSelected" type="submit" value="Time Sheet"/>
<input name="ButtonSelected" type="submit" value="Previous Day"/>
<input name="ButtonSelected" type="submit" value="Next Day"/>
<input name="ButtonSelected" type="submit" value="Add New Line"/>
<input name="ButtonSelected" type="submit" value="Save"/>
