先檢視一下AjaxElementLocatorFactory的源生程式碼

package org.openqa.selenium.support.pagefactory;

import org.openqa.selenium.SearchContext;

import java.lang.reflect.Field;

public class AjaxElementLocatorFactory implements ElementLocatorFactory {
  private final SearchContext searchContext;
  private final int timeOutInSeconds;

  public AjaxElementLocatorFactory(SearchContext searchContext, int timeOutInSeconds) {
    this.searchContext = searchContext;
    this.timeOutInSeconds = timeOutInSeconds;
  }

  public ElementLocator createLocator(Field field) {
    return new AjaxElementLocator(searchContext, field, timeOutInSeconds);
  }
}
 

AjaxElementLocatorFactory類是為了網頁動態程式碼而存在的。最終目的是拿到一個ElementLocator類的物件。

首先需要定義一個AjaxElementLocatorFactory的類

Class<?> cls = Class.forName("com.testReflect.FieldDemo");
 //使用FieldDemo類的class物件生成 例項
Object obj = cls.newInstance();
//通過Class類中getField(String name)： 獲取類特定的方法，name引數指定了屬性的名稱
Field field = cls.getField("num1");
AjaxElementLocatorFactory ajaxElementLocatorFactory = new AjaxElementLocatorFactory(driver, 5000);

ElementLocator elementLocator = ajaxElementLocatorFactory.createLocator(field);
