Answer a question

I am trying to change the input field value in a form input, but unable to do so.

Input value is at this URL

Email: Vela.admi@gmail.com PW: Testing@123

On the page form appears after these actions:

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" 

When I try to change it using selenium or even if JS, it doesn't seem to change when we submit the form by pressing "Send Order"

My code trails are:

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')

I have also tried

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

But still when I submit it doesn't seem to change.

To perform the following steps:

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"
4. Send the value 10000 to the <input> field.

You have to induce WebDriverWait for the element_to_be_clickable() and you can use the following Locator Strategies:

• Code Block:

  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()
