Java 如何组合Webelement并选择以使其具有可重用的功能。？

我是硒的新手

我使用Selenium Java创建了两个类文件，试图实现完全可重用的所有基本功能，我在这里尝试将参数从inputClass.Java传递到mainClass.Java到dropDown（）内，调用两个方法chooseElement（）和dElement（）

如果chooseElement（）是WebElement而ddeElement（）是Select，我所需要的就是从inputClass.java传递值以使下拉菜单正常工作。有人在我的代码里纠正我

提前谢谢

页面源代码：

<div id="autocomplete_chosen" class="chosen-container chosen-container-single" style="width: 300px;" title="">
<a class="chosen-single" tabindex="-1">
<span>Selenium</span>
<div>
<b/>
</div>
</a>
<div class="chosen-drop">

您得到的错误是由于ddElement方法中的以下行引起的

select.selectByIndex((int) dindex);

无法将对象强制转换为基元类型int。请改用整数

select.selectByIndex(((Integer) dindex).intValue());

但是，编写方法类的更好方法如下所示

dElement

方法可以包含在

下拉列表中，因为将它分离出来没有任何好处。
嘿，我想你可以再使用一行，比如WebElement myEle=chooseElement（int x，String path）；之后进行下拉（myEle，1，“课程”）；请正确地检查参数并尝试一下，这样您就可以将一些简单易读的东西，如
driver.findElement（By.Id（“someId”）
变成一些神秘的东西，如`chooseElement（1，“someId”）。。。为什么？在这种情况下，没有理由为核心API创建包装器。您真的应该花些时间阅读一些基本的Java/编程教程。@JeffC，有些公司更喜欢提供关键字驱动的自动化框架。这样，错误处理和日志记录就可以轻松处理，编程知识较少的人也可以创建简单的脚本。@sigil:谢谢，这很有效well@JeffC当前位置谢谢你的建议，我会记住的。仅供参考：我已经提到我是新手。我刚进入这个论坛学习编程作为第一步，请接受答案，这样问题就可以结束了
