Hovering to Display Select Box Options
The issue presented involves creating a select box that displays options on hover instead of after clicking. The code provided is a simple select box:
<select name="size"> <option value="small">Small</option> <option value="medium">Medium</option> <option value="large">Large</option> </select>
Solution
The provided jQuery solution aims to achieve the desired behavior:
$('#selectUl li:not(":first")').addClass('unselected'); $('#selectUl').hover( function(){ $(this).find('li').click( function(){ $('.unselected').removeClass('unselected'); $(this).siblings('li').addClass('unselected'); var index = $(this).index(); $('select option:selected').removeAttr('selected'); $('select[name=size]') .find('option:eq(' + index + ')') .attr('selected',true); }); }, function(){ });
Explanation
- The code initially hides all options except the first one by adding the "unselected" class.
- Upon hovering over the ul, it enables clicking on the options to change the selection.
- Clicking an option removes the "unselected" class from all others and adds it to the clicked option, ensuring it remains visible.
- The selected option's index is used to update the select element, making the change persistent.
Additional Features
The solution has been extended to include:
- An alert to demonstrate the updated select element's value.
- Styling to improve the visibility of the selected and hovered options.
- A plug-in approach for easier implementation in other projects.
- A guidance text element to explain the purpose of the select box.
