javascript - 如何使用 Selenium 和 Python 更改输入字段值

Question

我正在尝试更改表单输入中的输入字段值，但无法这样做。

输入值在此URL
Email: Vela.admi@gmail.comPW: Testing@123
在这些操作之后出现在页面上的表单:

1. on left side click on "Sell Order" red button in Dashboard widget
2. a popup will appear on click, select "Order Type" as "Limit"
3. a new formfield appears, named "Limit Price" 

当我尝试使用 selenium 甚至 JS 更改它时，当我们通过按“发送订单”提交表单时它似乎没有改变

我的代码轨迹是:

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
import time

driver.get(url)
driver.find_element_by_css_selector('#gwt-uid-770 > span > span > input').send_keys('6700')

我也试过

driver.execute_script("document.querySelector('#gwt-uid-770 > span > span > input').value=6700")

但是当我提交时，它似乎并没有改变。

要执行以下步骤:

在左侧单击仪表板小部件中的“卖出订单”红色按钮

点击会弹出一个窗口，选择“订单类型”为“限价”

出现一个新的表单域，名为“Limit Price”

发送值 10000到<input> field 。

你要诱导 WebDriverWait对于 element_to_be_clickable()您可以使用以下 Locator Strategies :

代码块:

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.get('https://primexbt.com/id/sign-in?redirect=%2Fmy%2Ftrade')
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[formcontrolname='email']"))).send_keys("Vela.admi@gmail.com")
driver.find_element_by_css_selector("input[formcontrolname='password']").send_keys("Testing@123")
driver.find_element_by_css_selector("span.mat-button-wrapper").click()
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.popup-close"))).click()
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe.ng-star-inserted")))
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "span.price.price-bid"))).click()
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//span[@class='selectBox--label' and text()='Market']"))).click()
WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//ul[@class='dropDown--list']//li[contains(., 'Limit')]"))).click()
element = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//label[text()='Limit Price']//following::span[1]//span[@class='numericStepper--input']//input[@class='gwt-TextBox']")))
ActionChains(driver).click(element).key_down(Keys.CONTROL).send_keys("a").key_up(Keys.CONTROL).send_keys("10000").perform()

备注 :在构建答案时:

Entry Price you set must be higher or equal to 9786.7
