Question: I am creating a new freestyle project in `Jenkins` and wanted to pass parameters with my batch file.

I created a multi-line string parameter in the `Command` section of the `Execute Windows batch command` box:

```
echo The build names are: %Build%

gitPull.bat (Pass in the variables here?)

```

But it only shows the first line of string.

After doing some research, I found out that batch command cannot handle multi-line strings, so I thought if the user can enter one line of string with comma between each string to separate it, then I could somehow store that in a variable.

For example:

```
"Hello,John,Doe"

```

Then I want to pass those variables separately into my batch file called `gitPull.bat` but I'm not sure how I can do this.

Answer: 
My Answer is for **Chrome Browser** 

* If you need to View event listeners registered on objects then you
can use [getEventListeners(object)](https://developers.google.com/web/tools/chrome-devtools/console/command-line-reference#geteventlistenersobject)
* If you need to monitor events use [monitorEvents()](https://developers.google.com/web/tools/chrome-devtools/console/command-line-reference#monitoreventsobject-events)

You can read [more about these API](https://developers.google.com/web/tools/chrome-devtools/console/events) 

You can also observe these events from the Dev tools

I don't know on others brows but at least in chrome console in elements tab on the right side you can open the *Event Listeners* tab and see them all, moreover clicking on it You will find where they have been set.[![enter image description here](https://i.stack.imgur.com/apql7.png)](https://i.stack.imgur.com/apql7.png)
