find submit button in selenium without id
提问by humanbeing
I have a button
我有一个按钮
<input type="submit" class="button button_main" style="margin-left: 1.5rem;" value="something">
I cannot find it by id or name and need to submit a form.
我无法通过 ID 或名称找到它，需要提交表格。
I tried doing this: Alternatively, WebDriver has the convenience method “submit” on every element. If you call this on an element within a form, WebDriver will walk up the DOM until it finds the enclosing form and then calls submit on that. If the element isn't in a form, then the NoSuchElementException will be raised: element.submit() http://selenium-python.readthedocs.org/navigating.html
我尝试这样做：或者，WebDriver 在每个元素上都有方便的方法“提交”。如果您在表单中的元素上调用 this，WebDriver 将遍历 DOM，直到找到封闭的表单，然后调用提交。如果元素不在表单中，则会引发 NoSuchElementException： element.submit() http://selenium-python.readthedocs.org/navigating.html
But that cannot find the submit selector either.
但这也找不到提交选择器。
ideas?

There are many options here, to name a few:
这里有很多选择，仅举几例：
If class alone is unique, you can use
如果单独的类是唯一的，您可以使用
driver.find_element_by_css_selector(".button_main").click()
If class + value combo is unique, you can use:
如果 class + value 组合是唯一的，则可以使用：
driver.find_element_by_css_selector(".button_main[value='something']").click()
You can also use xpath:
您还可以使用 xpath：
driver.find_element_by_xpath("//input[@type='submit' and @value='something']").click()
If none of those work (i.e. they are not identifying button uniquely), look at the elements above the button (for example <form) and provide the xpath in format:
如果这些都不起作用（即它们不是唯一标识按钮），请查看按钮上方的元素（例如<form）并以格式提供 xpath：
driver.find_element_by_xpath("//unique_parent//input[@type="submit" and @value='something']").click()

You could try to find the element with an XPath expression or a CSS selector like input[type="button"], and then just click the element.
您可以尝试使用 XPath 表达式或 CSS 选择器（如 input[type="button"]）查找元素，然后单击该元素。

i recommend xpath chrome extension, with it you will be able to get the path by running the extension and shift-clicking on the element you want this chrome extension https://chrome.google.com/webstore/detail/xpath-helper/hgimnogjllphhhkhlmebbmlgjoejdpjl
我推荐 xpath chrome 扩展程序，有了它，您将能够通过运行扩展程序并按住 Shift 键单击您想要此 chrome 扩展程序的元素来获取路径https://chrome.google.com/webstore/detail/xpath-helper/ hgimnogjllphhhkhlmebbmlgjoejdpjl
