在“每个步骤脚本工具桌面“中编辑脚本时，可以添加自定义 C# 代码。请参阅每个步骤脚本工具对象模型：类、方法、属性等，以查找有关每个步骤脚本自定义的详细信息。

使用自定义 C# 代码编辑的脚本在保存之前需要获得技术支持团队的批准。每次添加自定义 C# 代码或编辑包含自定义 C# 代码的脚本时，将自动发送脚本以供审批。请注意，我们的团队可能需要一些时间来审核和批准脚本以供使用。

下面是将 C# 添加到脚本中以使用条件语句和随机定义的变量的一些示例：

在内容验证错误上中止脚本执行
条件弹出窗口管理
条件操作：将商品添加到购物车或候补名单（如果缺货）
注册过程的电子邮件随机化
进入18至12岁之间的年龄。
随机选择男性或女性性别
从在线产品目录中随机挑选项目

条件语句示例

在内容验证错误上中止脚本执行

Step (1, "test - https://www.test.com");
tab0 = Tabs.NewTab ();
tab0.GoTo ("https://www.test.com");
if ( !tab0.Text.Contains("<KEYWORD>"))
{
return;
}

例如，如果找不到”登录“关键字，则中止脚本，添加：

if (!tab0.Text.Contains("Login"))

关闭条件弹出窗口（如果出现）

脚本重播条件可能因地理区域、时间等而异。因此，在我们重播脚本时，可以根据条件显示某些内容，例如弹出窗口。若要指定如何管理目标网站上的条件内容，请将 if 语句添加到“每个步骤”脚本中。

例如，在脚本重播期间关闭页面上显示的弹出窗口并导航到新页面

记录脚本，并在页面上显示弹出窗口。
或者：如果您有 Xpath 在目标页面上找到“关闭”按钮，则可以在没有弹出窗口的情况下录制脚本。
在预期显示弹出窗口的步骤中添加 if 语句。使用“关闭”按钮 Xpath 指定条件。

请注意，我们在 “if” 测试表达式中使用 WaitForElement 方法来等待弹出窗口加载：

tab0.WaitForElement (TimeSpan timeout, string xpath)

// script_version=3.0; everystep_version=0; date=4/8/2022; Chrome=91.0.4472.77
NetworkFilter.Deny ("https://www.adidas.com/api/chk/customer/baskets?sitePath=us");
Tabs.SetSize (1820, 513);
DMBrowser tab0 = null;
Step (1, "adidas Official Website | adidas US - https://www.adidas.com/us/kids");
tab0 = Tabs.NewTab ();
tab0.GoTo ("https://www.adidas.com/");
tab0.Link ("//A[normalize-space(text())=\"KIDS\"]", "//A[normalize-space()=\"3 STRIPE LIFE\"]/../preceding-sibling::DIV[2]//A[normalize-space()=\"KIDS\"]", "//A[normalize-space()=\"Give Back\"]/../preceding-sibling::DIV[3]//A[normalize-space()=\"KIDS\"]").Click ();
Step (2, "Kids Shoes and Clothing | adidas US - https://www.adidas.com/us/kids");
//Waits for pop-up window with the "Close" button to appear on the page for 5 seconds. 
if (tab0.WaitForElement("5sec".ToDuration (), "//*[@ID=\"modal-root\"]/DIV/DIV/BUTTON", "//BUTTON[@ARIA-LABEL=\"Close\"]"))
{
//If the "Close" button detected, clicks the button to close the pop-up. Otherwise, jumps to the next line.
 tab0.Button ("//*[@ID=\"modal-root\"]/DIV/DIV/BUTTON", "//BUTTON[@ARIA-LABEL=\"Close\"]").Click ();
}
tab0.Span ("//A[normalize-space(@TITLE)=\"SHOP NOW\"]//SPAN[normalize-space()=\"SHOP NOW\"]", "//A[normalize-space(@TITLE)=\"SHOP NOW\"]//SPAN[normalize-space(text())=\"SHOP NOW\"]", "(//SPAN[normalize-space(text())=\"SHOP NOW\"])[1]").Click ();
Step (3, "Kids - Ultraboost 22 | adidas US - https://www.adidas.com/us/kids-ultraboost_22");

将商品添加到购物车或候补名单（如果商品不可用）

如果。。。else 语句让您的脚本执行特定操作，如按钮单击、Chekbox 检查、导航到另一个 URL 等。基于指定的条件。例如，您可以记录“添加到购物车”交易，并希望脚本将商品添加到购物车，或者，如果商品缺货，则添加到等待列表。您可以通过添加 if…否则声明：

记录购物车交易。
要指定测试表达式，请选择声明商品有库存的元素，例如“立即购买”按钮。
使用 tab0 导航到项目页面后指定“if”语句。WaitForElement （TimeSpan timeout， string xpath） 方法与 “Buy Now” 按钮 Xpath.
指定在该项可用作“if”语句时要执行的操作。例如，“立即购买”点击。
指定在商品缺货（未检测到“立即购买”按钮）时要执行的操作作为“else”语句。例如，“添加到列表”单击。

技巧

要指定备用流操作，请在同一脚本中记录除默认流之外的操作。然后在“else”语句中使用相关行。

检查下面提供的示例。

数据随机化

注册过程的电子邮件随机化

要在注册过程中使用随机生成的电子邮件，您可以使用类似于以下内容的随机生成的值声明一个新变量：

string mail = ("test" + Guid.NewGuid().ToString("N") + "@gmail.com");

使用该变量作为电子邮件字段的 TypeText 方法参数，如下所示：

tab0.TextField ("//INPUT[@TYPE=\"text\"]", "//INPUT[@ID=\"Contact_Email_Addr\"]", "//INPUT).TypeText (mail.ToString ());

// script_version=3.0; everystep_version=4.0.8108.2121; date=4/8/2022; Chrome=91.0.4472.77
