§ 00AJAX (vanilla JS) + Customer Support Formplatform-specific integration guide

Why AJAX (vanilla JS) developers choose splitforms for customer support form

The customer support form 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 · support

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

Use the HTML snippet on this page, keep the customer support form 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 your name, email, phone (for urgent issues), order / account id (optional), how urgent is this?, what's wrong?. Required fields are your name, email, how urgent is this? and what's wrong?.

native ajax (vanilla js) reality

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

use case fit

Live chat plugins start at $50-100/month per seat. For low-volume support, a structured contact form plus a Starter webhook into Linear or Help Scout does the same job for far less.

§ 03bCustomer Support Contact Form (Help Desk)template-specific playbook

The reason this customer support form exists.

Webhooks into Linear / Notion / Help Scout / Zendesk · category-based routing.

why it matters

Support tools (Zendesk, Intercom, Help Scout) start at $20-100/seat/month. For early-stage SaaS handling 10-50 tickets a week, a structured support form that webhooks into Linear / Notion / Slack handles the volume without the subscription. The form captures ticket category (billing / bug / feature request / account access / general), urgency (blocking / high / medium / low), account email, and description. Routing the categories to different Slack channels or Linear teams turns the form into a triage layer. As you scale, switch the webhook target to Zendesk or Intercom and the form stays — same UX, different backend. SLA tracking still works because submission timestamps are stored.

route the submission

Capture ticket category

Required: category (billing / bug / feature / account / general), urgency, account email, description. Optional: screenshot upload (Pro), order/invoice number for billing.

Route by category

Webhook branches on category — billing goes to finance Slack; bugs to engineering Linear; feature requests to product Productboard. Each team owns their queue.

Auto-confirm with SLA

Auto-respond with ticket number and SLA promise ('we'll reply within 24 hours on weekdays'). Sets expectations and reduces the 'have you seen this?' follow-up email two days later.

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

What changes when this customer support form 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 customer support form 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 customer support form 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" />
03  <input type="hidden" name="redirect"   value="/thanks.html" />
04  <input name="email" type="email" required />
05  <button type="submit">Send</button>
06</form>
07<script>
08  document.getElementById("cf").addEventListener("submit", async (e) => {
09    e.preventDefault();
10    const r = await fetch(e.target.action, { method: "POST", body: new FormData(e.target) });
11    if ((await r.json()).success) location.href = "/thanks.html";
12  });

§ 06Questions9 answered

Customer Support Form on AJAX (vanilla JS) — FAQ.

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

01Does this customer support form 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 customer support form 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 (your name, email, phone (for urgent issues), order / account id (optional)…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the customer support form?

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 customer support form 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 integrate with Zendesk / Intercom / Help Scout?

When ticket volume crosses ~50/week, the dedicated tool's UX (queue management, canned responses, customer history) starts paying back the subscription. Below that, webhooks into Linear or Slack handle volume cheaper. Switch when you outgrow the simpler tools, not before.

08How do I handle SLA tracking without a help desk?

splitforms timestamps every submission. A daily Zapier / Make automation flags any unresponded submission older than your SLA threshold and pings the owning team in Slack. Crude but effective for small teams. At scale, switch to a tool that tracks time-to-first-response natively.

09Can I integrate with Linear / Notion / Productboard?

Yes — webhook the JSON. Linear and Notion both accept issue / database creation via API. Productboard accepts feature requests via Zapier. Routing categories to the right tool (bugs to Linear, features to Productboard) means each gets triaged in the place that team works.
