我已成功选择<a>标记。我想显示锚标记的文本，我无法这样做。
我正在使用selenium，mocha，javascript和phantomJS
这是我的脚本（详细信息）：
var assert = require('assert');
var test = require('selenium-webdriver/testing');
var webdriver = require('selenium-webdriver');
var By = webdriver.By;
var until = webdriver.until;
var equals = webdriver.equals;
/*-------login details--------*/
var userAdmin = 'saswat@matrixnmedia.com';
var passAdmin = 'DarkPrince2012';
var userTradeshow = 'joni@mailinator.com';
var passTradeshow = 'Mithun@';
/*-----login details ends-----*/
/*---setting up credentials---*/
var passArgument = process.env.KEY; /*fetch value from the environment value;*/
console.log("You chose to enter as '"+passArgument+"'");
if(passArgument.toLowerCase().indexOf("admin")>-1)
{
var username = userAdmin,
password = passAdmin;
}
else if(passArgument.toLowerCase().indexOf("trade")>-1)
{
var username = userTradeshow,
password = passTradeshow;
}
else
{
var username = "",
password = "";
}
/*-setting up credentials ends-*/
test.describe('TrackRevenue Test', function()
{
test.it('should work', function()
{
var driver = new webdriver.Builder()
.withCapabilities(webdriver.Capabilities.phantomjs())
.build();
var loginFlag = 0;
var baseUrl = 'http://saswatr3.ouh.co/login';
var expectedTitle = "Track Revenue";
var successMessage = "Welcome to the admin page!";
driver.get(baseUrl);
driver.getTitle().then(function(title)
{
if(expectedTitle === title)
{
console.log("Verification Successful - The correct title is displayed on the web page.");
}
else
{
console.log("Verification Failed - An incorrect title is displayed on the web page.");
}
});
driver.findElement(By.id('username')).sendKeys(username);
driver.findElement(By.id('password')).sendKeys(password);
driver.findElement(By.id('_submit')).click();
driver.findElements(By.xpath("//a[contains(text(), 'Log out')]")).then(function(elements_arr)
{
if(elements_arr.length > 0)
{
loginFlag = 1;
driver.findElements(By.xpath("//a[contains(@class, 'user-name m-r-sm text-muted welcome-message')]")).then(function(e){
if(e.length > 0)
{
console.log("No. of elements :"+e.length);
console.log("Found The USerName : ");
console.log("Username : "+e[0].text);//this is the line with the issue. It prints undefined
}
});
}
else
{
driver.findElements(By.xpath("//div[contains(text(), 'Invalid credentials.')]")).then(function(elements_arr2)
{
if(elements_arr2.length > 0)
console.log("Login Unsuccessful, div invalid credentials found");
else
console.log("Login Unsuccessful, div invalid credentials not found");
});
}
if(loginFlag == 1)
console.log("Login Successful");
else
console.log("Login Unsuccessful");
});
driver.quit();
});
});
我的问题在于这个脚本。
driver.findElements(By.xpath("//a[contains(@class, 'user-name m-r-sm text-muted welcome-message')]")).then(function(e){
if(e.length > 0)
{
console.log("No. of elements :"+e.length);
console.log("Found The USerName : ");
console.log("Username : "+e[0].text);//this is the line with the issue. It prints undefined
}
});
如您所见，console.log("Username : "+e[0].text);导致问题。
为方便起见，这是我得到的完整信息。

现在，当我做出如下修改时：
driver.findElements(By.xpath("//a[contains(@class, 'user-name m-r-sm text-muted welcome-message')]")).then(function(e){
if(e.length > 0)
{
console.log("No. of elements :"+e.length);
console.log("Found The USerName : ");
console.log("Username : "+e.text);//this is the line with the issue. It prints undefined
}
});
这是我得到的信息。

我做了以下更改：
driver.findElements(By.xpath("//a[contains(@class, 'user-name m-r-sm text-muted welcome-message')]")).then(function(e){
if(e.length > 0)
{
console.log("No. of elements :"+e.length);
console.log("Found The USerName : ");
console.log("Username : "+e[0].getText());
}
});
以下是信息：

答案 0 :(得分：3)
您正在使用复数findElement s ，它会为您提供元素列表。对列表使用e.text不会起作用，因为你只能将.text与web对象一起使用。
使用单数版本获取页面上的第一个匹配项： driver.findElement（）
如果您确实需要获取列表中只有一个元素的文本，请使用 e [0] .text 来获取列表中第一个元素的文本。
