Introduction: When deadlines, schedules, or time-sensitive choices are involved, picking the right checkbox can feel like a guessing game. But what if your form could do the thinking for you?
By linking checkboxes to a calendar field, your form becomes dynamic—automatically selecting the correct option based on the timeframe you choose.
Test Version: Laserfiche Forms Professional Version 12.0.2503.10378
Code Provided by: William Bentley with Texas A&M
Setup: Download codes from Bait and Tackle.
Checkbox Autofill based on Current Date - Classic Designer
1. Add a Checkbox field and a Date field to your form.
2. Apply CSS classes to each field:
• Assign semesterCheckbox to the Checkbox field.
• Assign selectedDate to the Date field.
3. Open the form’s CSS and JavaScript panel.
In Laserfiche Forms Classic Designer, select CSS and JavaScript at the top of the designer interface to access the script editor.
4. Copy and paste the JavaScript code from Day 6 Bait and Tackle library.
This applies the Day 6 logic and behavior to your Checkbox and Date fields.
5. Update the field IDs and variable names as needed.
Ensure the script references the correct IDs for your Checkbox field and Date field.
