JAWS Screen Reader Focus Management After Redirect

How to fix JAWS screen reader reading entire page after redirect when focus is programmatically set to a heading?
I’m experiencing an accessibility issue where JAWS screen reader reads the entire page content after a redirect, even when focus is programmatically moved to a specific heading. This behavior differs from NVDA and VoiceOver which correctly announce only the focused heading.
Problem details:
- User clicks a button/link on Page A
- User is redirected to Page B
- On Page B, focus is moved to a static heading using tabindex=“-1”
- A widget loads asynchronously, and the heading text appears after data is available
Current behavior:
- NVDA: Correctly announces the focused heading once content loads
- VoiceOver: Works as expected
- JAWS: Visual focus stays on heading but reads entire page from top
Expected behavior:
JAWS should only announce the focused heading, similar to other screen readers.
Code implementation:
Static heading:
<h2
class="phw-s-match-link-text"
tabindex="-1"
>
Match
</h2>
Navigation button:
<a
v-phw-href="'pageB'"
aria-label="Match link"
>
<span>
Match link
</span>
</a>
Focus logic:
function focusOnUploadedText() {
const focElem = element.value.querySelector('.phw-s-match-link-text');
setTimeout(() => {
focElem && focElem.focus();
}, 100);
}
What are the proper techniques to ensure JAWS respects programmatic focus changes after page redirects and only announces the focused element?
When JAWS screen reader reads the entire page content after a redirect despite programmatic focus being set to a specific heading, this is a known accessibility issue related to JAWS’s interaction behavior after page loads. To resolve this, you need to implement proper focus management techniques that account for JAWS’s specific handling of virtual cursor focus after redirects.

Understanding the JAWS Focus Issue
JAWS screen reader has unique behavior patterns when handling programmatic focus after redirects. Unlike NVDA and VoiceOver, JAWS often doesn’t announce the focused element immediately after a redirect when focus is set programmatically. Instead, it may continue reading from the top of the page or enter a different interaction mode.
According to the Accessibility Developer Guide, “When the screen reader’s cursor is on an editable element, it allows to switch to focus mode using the Enter key. When focus mode is active, a ‘beep’ sound is played. By pressing Esc, focus mode can be left (announced by a different ‘beep’ sound) and browse mode is active again.”
This behavior becomes particularly problematic with non-interactive elements like headings, especially when combined with asynchronous content loading.
Core Problem Analysis
The issue stems from JAWS handling of virtual cursor focus after page loads. As noted in the FreedomScientific standards support issue, “When navigating by content (headings, arrowing through the page, etc), the first time a user press Enter or Space while the virtual cursor is on non-interactive content after a fresh page load (but not a refresh), JAWS will move virtual cursor focus to the top of the page (rather, it loses focus and the user has to start over).”
Your implementation has several contributing factors:
- Setting focus to a heading with
tabindex="-1" - Using a redirect (not an in-page navigation)
- Delaying the focus setting with
setTimeout - The heading content loading asynchronously
Immediate Solutions
1. Use Interactive Elements Instead of Headings
Rather than using a heading with tabindex="-1", consider using a button or link that maintains keyboard accessibility:
<button
class="phw-s-match-link-text"
aria-label="Match"
onclick="handleMatchClick()"
>
Match
</button>
This approach works better with JAWS’s focus mode, as mentioned in the Tink.uk guide: “JAWS will automatically enter/exit forms mode whichever method is used to move focus to the field.”
2. Implement Proper Focus Timing
Remove the setTimeout delay and set focus immediately after the redirect:
function focusOnUploadedText() {
const focElem = element.value.querySelector('.phw-s-match-link-text');
focElem && focElem.focus();
}
3. Add Screen Reader Announcements
Include ARIA live regions to provide context to JAWS:
<div aria-live="polite" class="sr-only" id="focus-announcement">
<!-- Content will be announced by screen readers -->
</div>
<script>
function focusOnUploadedText() {
const focElem = element.value.querySelector('.phw-s-match-link-text');
const announcement = document.getElementById('focus-announcement');
// Set announcement content
announcement.textContent = "Match details loaded";
// Set focus
focElem && focElem.focus();
}
</script>
Advanced Focus Management Techniques
1. Use Navigation Landmarks
Implement proper ARIA landmarks to help screen readers understand the page structure:
<nav aria-label="Breadcrumb">
<!-- Breadcrumb content -->
</nav>
<main>
<h2 id="match-heading" class="phw-s-match-link-text">Match</h2>
<!-- Rest of content -->
</main>
According to the VA.gov team’s solution, “It appears this can be remediated by setting focus on the breadcrumb
2. Implement Progressive Enhancement
Ensure the heading content is available before setting focus:
<h2 id="match-heading" class="phw-s-match-link-text" aria-hidden="true">
Match
</h2>
<script>
function focusOnUploadedText() {
// Wait until content is actually loaded
checkContentReady(() => {
const focElem = document.getElementById('match-heading');
focElem.removeAttribute('aria-hidden');
focElem.focus();
});
}
function checkContentReady(callback, attempts = 0) {
if (element.value.querySelector('.phw-s-match-link-text').textContent.trim()) {
callback();
} else if (attempts < 50) {
setTimeout(() => checkContentReady(callback, attempts + 1), 100);
}
}
</script>
3. Use JAWS-Specific Focus Management
For JAWS-specific handling, consider adding a brief delay after the redirect before setting focus:
function focusOnUploadedText() {
const focElem = element.value.querySelector('.phw-s-match-link-text');
// JAWS often needs more time after redirect
setTimeout(() => {
focElem && focElem.focus();
// Additional announcement for JAWS
focElem.setAttribute('aria-live', 'polite');
setTimeout(() => {
focElem.removeAttribute('aria-live');
}, 1000);
}, 300); // Increased delay for JAWS
}
Asynchronous Content Loading
The asynchronous loading of your widget significantly impacts the issue. Here’s a robust solution:
1. Content-First Approach
Load content before redirecting:
async function navigateToPageB() {
// Pre-load content
await loadMatchContent();
// Then redirect
window.location.href = 'pageB';
}
function loadMatchContent() {
return new Promise((resolve) => {
fetch('/api/match-data')
.then(response => response.json())
.then(data => {
// Store data for page B
sessionStorage.setItem('matchData', JSON.stringify(data));
resolve();
});
});
}
On Page B:
document.addEventListener('DOMContentLoaded', () => {
const matchData = JSON.parse(sessionStorage.getItem('matchData'));
if (matchData) {
displayMatchContent(matchData);
focusOnUploadedText();
}
});
2. Client-Side Navigation
Consider using client-side routing instead of full page redirects:
function navigateToPageB() {
// Load content dynamically
fetchPageContent('pageB').then(html => {
document.body.innerHTML = html;
// Set focus after DOM is ready
setTimeout(() => {
const focElem = document.querySelector('.phw-s-match-link-text');
focElem && focElem.focus();
}, 100);
});
}
Testing and Validation
1. JAWS Configuration
Ensure JAWS is properly configured for your application. Users may need to:
- Disable “Auto Forms Mode” for your specific site
- Adjust Virtual Cursor settings
- Update to the latest JAWS version
2. Cross-Screen Reader Testing
Test across all major screen readers:
- JAWS (latest version)
- NVDA (latest version)
- VoiceOver (macOS/iOS)
- TalkBack (Android)
3. Automated Testing
Use automated accessibility tools to verify focus management:
- Axe-core
- WAVE
- Lighthouse accessibility audits
4. User Testing
Conduct user testing with actual JAWS users to validate solutions. The Stack Overflow discussion highlights that “If you move the focus to a specific element when the page loads, JAWS will likely read the page from that point to the bottom. This is expected behaviour, and most users will know how to stop JAWS from reading.”
Conclusion
Fixing JAWS screen reader focus issues after redirects requires understanding JAWS’s unique interaction patterns. The key solutions include using interactive elements instead of headings, implementing proper focus timing, adding screen reader announcements, and ensuring content is available before setting focus. For complex applications, consider client-side navigation or pre-loading content to provide a more predictable experience across all screen readers. Remember that user testing with actual JAWS users remains the most reliable validation method for accessibility solutions.
