Helium文档10-WebUI自动化-Text识别网页上的任何文本或标签

前言

Text关键字的作用是识别网页上的文字，在一般UI查找中使用率非常高，但是需要注意，如果网页上有相同的文字，那么只能识别到第一个 

入参介绍

以下是Text的源码

有5个如参：后面4个参数是上下左右的定位辅助，后面举例中详细介绍

text=None, below=None, to_right_of=None, above=None, to_left_of=Noneclass Text(HTMLElement):    """    Lets you identify any text or label on a web page. This is most useful for

    checking whether a particular text exists::

        if Text("Do you want to proceed?").exists():
            click("Yes")

    ``Text`` also makes it possible to read plain text data from a web page. For
    example, suppose you have a table of people's email addresses. Then you
    can read John's email addresses as follows::

        Text(below="Email", to_right_of="John").value

    Similarly to ``below`` and ``to_right_of``, the keyword parameters ``above``
    and ``to_left_of`` can be used to search for texts above and to the left of
    other web elements.

    def __init__(
            self, text=None, below=None, to_right_of=None, above=None,
            to_left_of=None
    ):
        super(Text, self).__init__(
            below=below, to_right_of=to_right_of, above=above,
            to_left_of=to_left_of
        )
        self._args.append(text)
    @property
    def value(self):
        """
        Returns the current value of this Text object.
        """
        return self._impl.value

举例说明

1、查找文字Text("Java教程")

from helium import *
import time

def gaokao10():
    start_chrome(url)
    time.sleep(2)
    wait_until(Text("推荐教程").exists)
    highlight(Text("Java教程")) 
    time.sleep(5) 
    kill_browser() 
gaokao10()

2、Text("Java教程", below="推荐教程")

from helium import *
import time

def gaokao10():
    start_chrome(url)
    time.sleep(2)
    wait_until(Text("推荐教程").exists)
    highlight(Text("Java教程", below="推荐教程"))
    time.sleep(5)
    kill_browser()

gaokao10()
