这是一个示例代码文件，可以直接在这里写Python代码，然后在程序中的exec操作中调用。如果此文件名称为myCode.py，请将此文件放置在EasySpider程序目录下（和Data/文件夹同级），那么在程序中的exec操作中可以直接写outside:myCode.py来调用此文件中的代码，示例：
|
||
|
||
1. 用self.browser表示当前操作的浏览器，可直接用selenium的API进行操作，如self.browser.find_element(By.CSS_SELECTOR, "body").send_keys(Keys.END)即可滚动到页面最下方。
|
||
2. 自定义一个全局变量：self.myVar = 1
|
||
3. 操纵上面定义的全局变量：self.myVar = self.myVar + 1
|
||
4. 打印上面定义的全局变量：print(self.myVar)
|
||
5. 将自定义变量的值赋值为某个字段提取的值：self.myVar = self.outputParameters["字段名"]
|
||
6. 修改某个字段提取的值：self.outputParameters["字段名"] = "新值"
|
||
|
||
对于更加复杂的操作，请直接下载源代码并编译执行。

This is a sample code snippet file. You can directly write Python code here, and then call it in the program using an `exec` operation. If this file is named myCode.py, please place this file under the EasySpider program directory (at the same level as the Data/ folder). Then, in the program's `exec` operation, you can directly write outside:myCode.py to invoke the code from this file. Examples:
|
||
|
||
1. Use self.browser to refer to the current browser being operated on. You can directly utilize the selenium API to perform actions. For instance, self.browser.find_element(By.CSS_SELECTOR, "body").send_keys(Keys.END) will scroll to the bottom of the page.
|
||
2. Define a global variable: self.myVar = 1
|
||
3. Manipulate the above-defined global variable: self.myVar = self.myVar + 1
|
||
4. Print the above-defined global variable: print(self.myVar)
|
||
5. Assign a value to the custom variable from a value extracted for some field: self.myVar = self.outputParameters["field name"]
|
||
6. Modify the value extracted for some field: self.outputParameters["field name"] = "new value"
|
||
|
||
For more complex operations, please download the source code and compile it for execution.
