javascript - WebDriver JavascriptExecutor 不工作

Question

我正在尝试使用 Selenium WebDriver 中的 JavaScript 填写网页上的文本框。同事this github 在线存储库，用于填写文本框以加快速度。

当我运行该程序时，它会在 ((JavascriptExecutor)driver).executeScript("(function( window ) { 'use strict';" 处抛出错误，然后它会遍历每个文本框，但不会将文本添加到框中。昨天我和我的同事查看了它很长一段时间，比较了我们的代码，但无法找出问题所在。这是我的代码及其产生的错误。

感谢任何帮助。

Java 代码

InputStream inputStream = ClientInformationComponent.class.getResourceAsStream("AutoFillClientInsuredComponent.js");

StringWriter writer = new StringWriter();

try 
{
    IOUtils.copy(inputStream, writer, "UTF-8");
} 
catch (IOException e) 
{
    e.printStackTrace();
}

for (ClientDAO client : clients)
{
    String script = writer.toString();

    try
    {
        if (driver instanceof JavascriptExecutor) 
        {
            //ERROR IS THROWN HERE webdriver.components.ClientInformationComponent.fill(ClientInformationComponent.java:128)
            ((JavascriptExecutor)driver).executeScript("(function( window ) { 'use strict';"    
                    + "var lastName = '" + client.getLastName() + "';"
                    + "var firstName = '" + client.getFirstName() + "';"
                    + "var middleName = '" + client.getMiddleName() + "';"
                    + "var suffix = '" + client.getSuffix() + "';"
                    + "var streetAddress = '" + client.getMemberAddress() + "';"
                    + "var city = '" + client.getMemberCity() + "';"
                    + "var zipCode = '" + client.getMemberZipCode() + "';"                          + "var birthDate = '" + client.getDateOfBirth() + "';"
                    + "var homePhoneNumber = '" + client.getHomePhone() + "';"
                    + script);
        }
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
}

JavaScript 文件

var document = window.document,
  fieldValueMap = {
        "LastName"              : lastName,
        "FirstName"             : firstName,
        "MiddleName"            : middleName,
        "Suffix"                : suffix,
        "MemberAddress"         : streetAddress,
        "MemberCity"            : city,
        "MemberZipCode"         : zipCode,
        "MemberZipCodeSuffix"   : memberZipCodeSuffix,
        "DateOfBirth"           : birthDate,
        "HomePhone"             : homePhoneNumber

  };

Object.keys( fieldValueMap ).forEach(function( name ){

    var input = document.querySelector( "form input[name='" + name + "']" )
                    || document.querySelector( "form select[name='" + name + "']" )
        || document.querySelector( "form textarea[name='" + name + "']" );

    input && input.type !== "hidden" && ( input.value = fieldValueMap[ name ] );
});

})( window );

Answer 1

我们发现了问题所在。我们使用 IE 9 和文档 here指出如果 <!DOCTYPE html>标签不存在，IE 9 默认情况下将以 Quriks 模式(也称为兼容模式)显示页面。

通过添加 <!DOCTYPE html>标签将使页面呈现为 IE 9 并且不使用 Quirks 模式。您可能还必须包含 meta标签<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9"> meta如果需要，标签还允许您通过执行 content="IE=EmulateIE# 来模拟特定版本的 IE。或content=IE#

我们遇到的问题是旧版本的 IE 不支持我们使用的 JavaScript 方法。我们尝试并尝试将一些方法更改为较旧的样式，但我们不断遇到越来越多的旧 IE 版本不支持的方法的兼容性问题。
