To add an onClick attribute to elements in Webflow for analytics (e.g., Google Analytics or custom tracking), you’ll need to either use the built-in Webflow tools or embed custom code.
1. Use Webflow’s Built-In Click Tracking (via Google Analytics 4 or GTM)
- If you're using Google Tag Manager or GA4, you can track clicks without manually adding
onClick using triggers and tags. - In Webflow, give your clickable element a unique ID or class:
- Select the element (e.g., button or link).
- In the right sidebar under Settings, give it a unique ID (e.g.,
cta-button). - In Google Tag Manager, create a Click Trigger (click ID or class) and link it to an Analytics Event Tag.
2. Add onClick Using Custom Code Embed Method
- If you must add a literal
onClick attribute (e.g., onClick="trackConversion()"), use an HTML Embed or adjust the existing Webflow-generated element via JavaScript. - Steps:
- Drag in an Embed component where needed.
- Add your element using inline HTML and include the
onClick attribute, like:<button onClick="trackFunction()">Click Me</button>
- Alternatively, use a script in the Page Settings → Before tag to attach events using JavaScript:
document.getElementById('cta-button').onclick = function() { trackFunction(); };
3. Use Attributes via Webflow’s Custom Attributes Panel
- Select the element in Webflow Designer.
- In the Settings panel (gear icon), scroll to Custom Attributes.
- Add a new attribute: name =
onClick, value = trackFunction(). - Caution: This method may not behave correctly for all use cases—Webflow may sanitize HTML and prevent inline JS from executing. Prefer JavaScript event listeners unless unavoidable.
4. Don't Forget to Define the Tracking Function
- Place your JavaScript function like
function trackFunction() { /* analytics logic */ } in the Page Settings → Before tag or in a Site-wide custom code area.
Summary
To track clicks in Webflow using an onClick attribute, either:
- Use Google Tag Manager with unique IDs/classes on elements, or
- Add
onClick via an Embed block, JavaScript event listener, or Custom Attributes (use with caution). Avoid direct inline JS when possible for better security and maintainability.
