Use text from the loop (If unchecked, the text entered each time will be the text from the "Input Value" text box below. If checked, it will use the text set within the loop.)

Index value (0 represents using the entire current loop text. If greater than 0, it represents the text index value separated by "~" within the current loop. For example, if the current loop text value is A~B, index value 1 represents inputting A, 2 represents inputting B, and 0 represents inputting A~B)

Please read the instructions first and then write the specific code in the input box above (not in this box). To execute a large amount of code, you can simply write "outside:myCode.py" and the program will read and execute the code within myCode.py under the EasySpider directory.
                         Be aware that statements containing exec and eval operations and XPath cannot be tested on the current page, and can only be run when they are actually called upon in a task.
This option is an advanced feature that allows direct manipulation of the running browser using Python code. You can also customize variables in the entire execution environment and perform operations such as modifying and assigning values. Here are some examples:
1. Use `self.browser` to refer to the current browser being operated. You can directly use Selenium's API to perform operations, such as `self.browser.find_element(By.CSS_SELECTOR, "body").send_keys(Keys.END)` to scroll to the bottom.
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 the value of a custom variable to the value extracted from a field: `self.myVar = self.outputParameters["Field Name"]`

If you want to record your custom variable as a field, please select the next option, "Get value of a Python expression (the "eval" operation)"

6. If you want to import and use a third-party library that the program itself does not carry, you need to first use tools such as pip to install this library locally, and then add the path of the installed library before import, like:
(1) In the system command line execute the following command to install the library:
pip install emotlib
(2) Write the following code in the code box:
sys.path.append("D:/Python38/Lib/site-packages") # Assume emotlib library exists in this path
import emotlib # Now you can use emotlib library
print(emotlib.emoji()) # Use one of its functions.

Please read the instructions first and then write the specific code in the input box above (not in this box). To execute a large amount of code, you can simply write "outside:myCode.py" and the program will read and execute the code within myCode.py under the EasySpider directory.
This option is an advanced feature that allows directly returning the expression value of Python code, and in other places, use Field["FieldName"] to represent the return value of this operation.. Here are some examples:
1. Return relevant values of the current browser object. Use `self.browser` to refer to the current browser being operated. You can directly use Selenium's API to perform operations, such as `self.browser.find_element(By.CSS_SELECTOR, "body").text` to return the text on the current page.
2. Return the value of a custom global variable: `self.myVar`
3. Return the result of a conditional statement: `self.myVar == 1`
4. Determining whether the value extracted from a certain field is equal to the value of a certain variable: self.outputParameters["field name"] == self.myVar

Please note that this feature does not support assigning values to variables. In other words, you cannot write something like `self.myVar = 1`. If you want to perform assignment operations, please select the previous option, "Run Python code on current environment (the "exec" operation)"

Whether to record the output/return value of the execution as a field:

No Yes

Convert parameter type to: Text (for single values estimated to exceed 10,000 in length, please choose Large Text) Integer (up to 9 digits) Floating Number (Decimal) Large Text (single value length exceeding 10,000 but less than 1,000,000) Date Time Date Time Small Text (single value length less than 50) Extra Large Text (single value length exceeding 1,000,000) Large Integer (more than 9 digits)

Clear values of other parameters before record as a field: No Yes

This operation will generate a new row of data: Yes No

Use index value from within the loop (if unchecked, the setting will be the value of the "Set Value" text box below. If checked, it will use the index value set within the loop's dropdown box.)

Relative index value of the loop value (0 represents using the entire current loop's text. If greater than 0, it represents the value of the text separated by "~" within the current loop. For example, if the current loop's text value is 2~3 and you enter 2 here, it means taking the second item of the text, which is value 3, indicating setting the dropdown box to the third item.)

Option switch Mode

Set value (not applicable for "Switch to the next option" mode)

Loop based on the expression value of Python code. Here are some examples:
1. Return relevant values of the current browser object. Use `self.browser` to refer to the current browser being operated. You can directly use Selenium's API to perform operations, such as `self.browser.find_element(By.CSS_SELECTOR, "body").text=="123"`, which checks whether the current page contains the text "123".
2. Return the value of a custom global variable: `self.myVar`
3. Return the result of a conditional statement: `self.myVar == 1`
4. Determining whether the value extracted from a certain field is equal to the value of a certain variable: self.outputParameters["field name"] == self.myVar
If the expression returns a value greater than 0 or evaluates to True, the loop continues; otherwise, it stops.

Use the expression value of Python code to determine whether a condition is satisfied. Here are some examples:
1. Return relevant values of the current browser object. Use `self.browser` to refer to the current browser being operated. You can directly use Selenium's API to perform operations, such as `self.browser.find_element(By.CSS_SELECTOR, "body").text=="123"`, which checks whether the current page contains the text "123".
2. Return the value of a custom global variable: `self.myVar`
3. Return the result of a conditional statement: `self.myVar == 1`
4. Determining whether the value extracted from a certain field is equal to the value of a certain variable: self.outputParameters["field name"] == self.myVar
If the expression returns a value greater than 0 or evaluates to True, the operations within this branch will be executed; otherwise, they will be skipped.
