When using the vue-cal library and encountering an issue where the tabindex skips dates, it is likely due to how focusable elements are rendered or managed within the component. Here's how you can troubleshoot and fix this issue:
---
1. Understand the Cause
Dynamic tabindex values: The component might not properly manage sequential tabindex values for each date.
Hidden/Disabled Elements: Some dates (e.g., out-of-range or disabled) may still have focusable properties but are skipped by browsers due to logic in the component.
Custom Templates: If you've customized the date cells, they may have missing or conflicting tabindex attributes.
---
2. Solutions
A. Use a Custom tabindex Management
If the default behavior skips dates, ensure each date cell is explicitly assigned a sequential tabindex dynamically:
In your script:
B. Check for Disabled or Hidden Dates
vue-cal might render disabled or hidden dates that are skipped during tabbing. To avoid this:
Add a condition to ensure disabled dates are excluded from the tabindex cycle:
In your custom cell rendering:
C. Override vue-cal Accessibility Defaults
If vue-cal manages tabindex internally, override its behavior by attaching a watcher to your dates or ensuring focus management aligns with the calendar's layout:
D. Upgrade or Report Issues
If you're using an older version of vue-cal, the issue might already be resolved in a newer release. Check the vue-cal GitHub repository for updates or open an issue if the problem persists.

3. Best Practices
Avoid assigning tabindex manually unless necessary.
Ensure all dates are rendered with the correct tabindex, even for custom templates.
Use tools like browser devtools to debug the DOM and verify tabindex values.
This should help resolve the skipping tabindex issue!.

2. Solutions
A. Use a Custom tabindex Management
If the default behavior skips dates, ensure each date cell is explicitly assigned a sequential tabindex dynamically:
JavaScript:
<vue-cal
v-model="selectedDate"
:custom-data="customTabindexData"
@cell-click="handleDateClick"
/>In your script:
JavaScript:
data() {
return {
customTabindexData: [],
selectedDate: null,
};
},
methods: {
handleDateClick(date) {
this.selectedDate = date;
},
assignTabindex() {
this.customTabindexData = this.generateTabindex();
},
generateTabindex() {
const data = [];
let index = 1;
// Populate the data array with tabindex for each date cell
for (let week of this.weeks) {
week.forEach((day) => {
data.push({ ...day, tabindex: index++ });
});
}
return data;
},
},
mounted() {
this.assignTabindex();
}
---B. Check for Disabled or Hidden Dates
vue-cal might render disabled or hidden dates that are skipped during tabbing. To avoid this:
Add a condition to ensure disabled dates are excluded from the tabindex cycle:
JavaScript:
<vue-cal
:events="events"
:disable-views="['years', 'months']"
@cell-click="handleDateClick"
/>In your custom cell rendering:
JavaScript:
<template v-slot:cell="cell">
<div
:tabindex="cell.isDisabled ? -1 : 0"
@keydown.enter="selectDate(cell.date)"
>
{{ cell.date }}
</div>
</template>C. Override vue-cal Accessibility Defaults
If vue-cal manages tabindex internally, override its behavior by attaching a watcher to your dates or ensuring focus management aligns with the calendar's layout:
JavaScript:
watch: {
selectedDate(newDate) {
const el = document.querySelector(`[data-date="${newDate}"]`);
if (el) el.focus();
},
},
---D. Upgrade or Report Issues
If you're using an older version of vue-cal, the issue might already be resolved in a newer release. Check the vue-cal GitHub repository for updates or open an issue if the problem persists.
