I’m working on a project where I need to extract the first name value from a HubSpot form and save it to a JavaScript variable. I’ve been struggling to figure out the right approach for this.
So far I attempted using URL parameters to grab the data but that didn’t work out. The HubSpot form fields don’t seem to be accessible through that method. I’m wondering if there’s a way to directly access the form input values using jQuery or plain JavaScript.
Has anyone successfully done something similar? What’s the best way to retrieve form field values from HubSpot forms and store them in variables for further processing?
Any code examples or guidance would be really helpful. Thanks in advance!
I encountered a similar challenge when working with HubSpot forms. The key is to use HubSpot’s provided APIs to handle the form submissions. Instead of relying on static selectors, utilize the onFormSubmit event, which allows you to directly access the values of the form fields as they are being submitted. This eliminates the need for conventional DOM manipulation and makes it much easier to retrieve the first name and other field values for processing. Trust me, this method is far more reliable than trying to fetch values post-rendering.
I’ve worked with HubSpot forms on client projects and found the easiest way is grabbing data during form initialization. When HubSpot renders the form, you can access it directly through their global variables. Check the hbspt.forms object in your console after the form loads - it’ll show all active forms on the page. Then just query the form instance and grab field values with regular JavaScript. This works way better than event-based methods since you don’t have to worry about timing issues during submissions. Just make sure the HubSpot script finishes loading before you try accessing these objects.
u can wait for the iframe to load n then use contentWindow to access the fields inside. I’ve done this with HubSpot forms before since they load in iframes. Try document.querySelector(‘iframe[src*=“hubspot”]’).contentWindow.document to target the iframe first, then grab ur firstname input from there.
Hook into HubSpot’s form events with their JavaScript API. Once the form loads, attach event listeners to grab the field data. Wait for the form to fully load before trying to access input elements - that’s key. I use document.querySelector to target the input field with name=“firstname” once it’s ready. You can also use the form’s onChange events to capture data as users type for real-time access. Wrap your code in a timeout or use MutationObserver since HubSpot forms load async and DOM elements won’t be available right away.
hey! same thing happened to me last month. use hubspot’s embed code callback function - it grabs the form data right when someone hits submit. just add a callback to your form embed script and pull the firstname value from the submission object. way easier than scraping dom elements after the fact.
