§ 00AJAX (vanilla JS) + Demo Requestplatform-specific integration guide

Why AJAX (vanilla JS) developers choose splitforms for demo request

The demo request on this page integrates with AJAX (vanilla JS)'s development workflow using the form markup in your AJAX (vanilla JS) project. Whether you're deploying to a static host or a server-rendered platform, the form posts standard <code>FormData</code> to splitforms, so your backend complexity stays at zero. AJAX (vanilla JS)'s ecosystem has strong tooling for UI, but form delivery is a separate concern that splitforms handles independently — Free includes spam filtering and a submissions dashboard; Starter adds email notifications and webhooks.

§ 00Quick answerHTML · lead capture

Yes — this is the shortest safe path for AJAX (vanilla JS).

Use the HTML snippet on this page, keep the demo request fields visible in your AJAX (vanilla JS) UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the HTML version, then replace YOUR_ACCESS_KEY.

The posted payload contains full name, work email, phone, company, your role, team size, what are you trying to solve?. Required fields are full name, work email, company, your role, team size and what are you trying to solve?.

native ajax (vanilla js) reality

Vanilla JS / AJAX forms have been the no-framework default since jQuery's heyday.

use case fit

Demo requests are the highest-intent leads a SaaS gets. The form qualifies on company size and use case so the AE walks into the demo prepared, not improvising.

§ 03bSaaS Demo Request Form (Sales Lead Capture)template-specific playbook

The reason this demo request exists.

Webhooks into HubSpot / Salesforce / Close · Chili Piper / Calendly routing.

why it matters

Demo requests cost the SaaS team real money — an AE spends 30-45 minutes on each call. Unqualified demos burn money. The form qualifies on company size, role, use case, current tools, and timeline. ICP-fit leads (right company size, right industry, right pain point) get the AE calendar slot; off-ICP get nurtured via email. The qualifying data also pre-loads the CRM so the AE walks in knowing the prospect's stack and use case — demo close rates climb 30-50% on prepared calls vs cold ones. Most B2B SaaS uses Calendly / Chili Piper for the booking step; the form is the gating layer in front of the calendar.

route the submission

Capture firmographic data

Required: name, work email, company, role, team size, use case (1-3 sentences). Optional: current tools, timeline, budget range.

Route by ICP fit

Webhook branches on company size and role — ICP-fit leads (e.g. 50+ team, ops/eng decision-maker) book the AE calendar instantly via Chili Piper / Calendly. Off-ICP get nurtured via email instead of burning AE time.

Push to CRM

Webhook to HubSpot / Salesforce / Close / Pipedrive with all qualifying fields prefilled. AE arrives at the demo prepared with the prospect's stack and use case in their notes.

§ 03cAJAX (vanilla JS) production notesnative path · deploy · gotchas

What changes when this demo request lives in AJAX (vanilla JS).

These notes come from the AJAX (vanilla JS) platform registry and are rendered on this template page so crawlers see the framework-specific answer without opening a separate guide.

without splitforms

Vanilla JS / AJAX forms have been the no-framework default since jQuery's heyday. Without splitforms, the 'AJAX' part is one fetch line; the operational part is everything else: a backend route, an SMTP provider, a database for submissions, a honeypot or reCAPTCHA, a thank-you page, error handling for HTTP 4xx/5xx, retry logic. For 'JS-only on a static host' setups (Cloudflare Pages, GitHub Pages, S3), there's literally no server to run the route on — historically that meant Formspree, Formspark, Web3Forms, Basin. Splitforms is the modern entry: same shape, better free tier, better spam filtering, and signed webhooks from Starter.

deploy notes

Vanilla JS deploys to any static host — the snippet is HTML + inline <script>, no build step. CSP: if your site sets connect-src 'self', add https://splitforms.com to the directive or fetch is blocked. Browser support: native fetch is in every browser back to Edge 18 — the snippet runs without polyfills on every market-share-relevant browser. The progressive-enhancement variant (Pattern B) keeps the form working when JS fails to load — useful on flaky networks, ad-blocked clients, or for accessibility tools that disable JS.

AJAX (vanilla JS) gotcha

Forgetting e.preventDefault() reloads the page

Without preventDefault, the browser does its own form submission to wherever the form's action attribute points (or the current page) AND your fetch runs. You see a flash, the page reloads, and your handler's effects are lost.

AJAX (vanilla JS) gotcha

FormData includes ALL form fields — even disabled ones get dropped

new FormData(form) skips inputs without a name attribute, skips disabled inputs, skips unchecked checkboxes/radios. If a field doesn't show up in your splitforms inbox, check whether it's disabled at submit time.

AJAX (vanilla JS) gotcha

fetch() doesn't reject on HTTP 4xx/5xx — only network errors

If splitforms returns a 401 (bad key) or 429 (rate limit), fetch resolves successfully. You have to check res.ok or data.success yourself. Wrapping in try/catch only catches network failures, not HTTP errors.

AJAX (vanilla JS) gotcha

Double-click submit fires two requests

Without disabling the button on the first click, a quick double-click sends two POSTs. Both succeed; the user sees one success message; you see two submissions. Always set button.disabled = true at the start of the handler.

PATTERN A

Pattern A — fetch + FormData + status element

Single submit listener. new FormData(form) reads inputs, append the access key, POST. Update an aria-live status <p> with the result. ~25 lines, no library. Use the same wiring for the demo request fields on this page.

pattern-a.htmlhtml16 lines

01<form id="cf">
02  <input name="email" type="email" required />
03  <textarea name="message" required></textarea>
04  <button type="submit">Send</button>
05  <p id="msg" aria-live="polite"></p>
06</form>
07<script>
08  document.getElementById("cf").addEventListener("submit", async (e) => {
09    e.preventDefault();
10    const fd = new FormData(e.currentTarget);
11    fd.append("access_key", "YOUR_ACCESS_KEY");
12    const r = await fetch("https://splitforms.com/api/submit", { method: "POST", body: fd });
13    const data = await r.json();
14    document.getElementById("msg").textContent = data.success ? "Thanks!" : (data.message || "Try again");
15  });
16</script>

PATTERN B

Pattern B — progressive enhancement (works without JS)

Form has a real action attribute and a redirect hidden field — works with JS disabled (browser POSTs natively, splitforms 302s). When JS is available, the listener intercepts for inline UX. Best of both worlds, no compromise. Use the same wiring for the demo request fields on this page.

pattern-b.htmlhtml13 lines

01<form id="cf" action="https://splitforms.com/api/submit" method="POST">
02  <input type="hidden" name="access_key" value="YOUR_ACCESS_KEY" />

09    e.preventDefault();
10    const r = await fetch(e.target.action, { method: "POST", body: new FormData(e.target) });

§ 06Questions9 answered

Demo Request on AJAX (vanilla JS) — FAQ.

Direct answers, no marketing fluff. Missing one? Email hello@splitforms.com.

01Does this demo request work on AJAX (vanilla JS)?

Yes. The form is plain HTML with a single POST endpoint, so it runs on any AJAX (vanilla JS) site without server-side code, plugins, or SDKs. Drop the snippet into a AJAX (vanilla JS) page or component and submissions land in your splitforms dashboard.

02How much does the demo request cost on AJAX (vanilla JS)?

Free for 500 submissions per month — no credit card, no trial. Pro is $5/mo for 5,000 submissions, and there's a one-time $59 3-year plan (15,000 submissions/mo for 36 months). The same pricing applies regardless of which framework hosts the form.

03Can I customize the fields?

Yes. The template ships with sensible defaults (full name, work email, phone, company…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the demo request?

A hidden honeypot field catches dumb bots, and a tuned classifier scores the rest. You only see real submissions in your dashboard. No CAPTCHA, no friction for human users — and it works the same on AJAX (vanilla JS) as on any other framework.

05Can I send the demo request submissions to Slack or Discord?

Yes. Webhooks are available on Starter and above, with auto-formatted payloads for Slack, Discord, and WhatsApp (via CallMeBot). Or send raw signed JSON to any URL — Zapier, n8n, your own server. Configure in the splitforms dashboard.

06Will it work on a static AJAX (vanilla JS) site?

Yes — the form posts directly to splitforms from the browser, so no server is involved. Works on Vercel, Netlify, GitHub Pages, Cloudflare Pages, S3, or any plain Apache host.

07Should I require a work email?

Yes — block free email domains (gmail / yahoo / hotmail) on the email field. Free-email demos are 80% tire-kickers; work email is a basic ICP filter. Use a regex pattern or a real-time validator like ZeroBounce / Hunter to enforce.

08Can I integrate with Chili Piper / Calendly?

Yes — Chili Piper natively pulls form data and routes to the right AE based on territory / industry / company size. Calendly for Sales Teams supports round-robin routing too. Webhook the qualified lead to the booker; the unqualified ones bypass the calendar.

09How do I handle off-ICP demo requests?

Auto-respond with self-serve resources — a recorded demo, free trial signup, pricing page link, customer case studies. Add to a long-term nurture sequence. Don't burn AE time but don't lose the lead either.

§ 07Comparisonvs Web3Forms · vs Formspree
