我正在尝试在反应中进行香草形式的验证。但是,当输入的值不正确时,实现会在表单提交时显示错误。
这是我的代码:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.binary_location = "/path/to/your/chrome/browser"
driver = webdriver.Chrome(chrome_options = options, executable_path=r'/path/to.your/chrome/driver')
...
但是当我输入正确的值时,错误仍会在表单提交时显示。我在做什么错了?
答案 0 :(得分:1)
在每次验证之前重置错误状态
validate = () => {
let memberIdError= '';
let firstNameError= '';
let lastNameError= '';
let emailAddressError = '';
if(!this.state.memberId){
memberIdError = 'Member ID can\'t be empty';
}
if(!this.state.firstName){
firstNameError = 'First Name can\'t be empty';
}
if(!this.state.lastName){
lastNameError = 'Last Name can\'t be empty';
}
if(!this.state.emailAddress.includes('@')) {
emailAddressError= 'Email Address can\'t be empty';
}
if(memberIdError || firstNameError || lastNameError || emailAddressError){
this.setState({memberIdError, firstNameError, lastNameError, emailAddressError });
return false;
}
return true;
}
在每次验证中,我们都将错误状态重置为空字符串”
