Could anyone provide guidance on how to reset a dropdown list value using a radio button selection? Specifically, I need the dropdown list to reset to its default "selected" option when a particular radio button is clicked.
Any recommended approaches using JavaScript and CSS?
To reset the dropdown menu to its initial option, follow these instructions. Below is the code snippet you need to use
<select id=dropdownMenu>
<option value=""></option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<input onclick="resetDropdown();" type="radio" name="selection" value="selection">
Here's the JavaScript code snippet to achieve this.
function resetDropdown {
$("#dropdownMenu option:first").attr("selected", true);
}
Here is an example of code for the initial element:
<select id=example>
<option value=""></option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
An example of a radio button would look like this:
<input onclick="document.getElementById('example').value = '';" type="radio" name="test" value="testing">
Make sure to replace the default value in the onclick event with the appropriate value for your dropdown menu.
Changing the selected index to 0 with Javascript:
<radio button with onchange event="doSomething()" />
