In some situations, you may need to add custom scripts to your forms. With Captain, you have a lot of functionalities and customization options available, without scripting. However, with custom JS scripts you gain full control over your form’s functionality. Let’s start improving the functionality and usability of your web forms. All you need is your custom script URL.
Go to Settings–Advanced– Form and tick the option Add a JS script to your form. Paste the script URL in the text box that shows up.
Use a reliable service to host your script files. This feature is available starting with the Master plan. Here is the CaptainForm features list.
If you need to track the numbers of users who submitted the form, simply add a script on the Thank-you Page.
