How to Correctly Retrieve the Selected Option from a Dropdown using jQuery?

Getting the Selected Option from a Dropdown with jQuery

When attempting to retrieve the selected option from a dropdown list using jQuery's $("#id").val() method, you may encounter scenarios where it fails. One such case arises when the selected option has an ID other than the dropdown itself.

Consider the following HTML code:

<label for="name">Name</label>
<input type="text" name="name">
Copy after login

In this example, the selected option has the ID "aioConceptName." Using $("#aioConceptName").val() will not return the value of the selected option because it pertains specifically to the dropdown element itself.

To retrieve the selected option correctly, you can utilize the following approach:

For Selected Text:

var conceptName = $('#aioConceptName').find(":selected").text();
Copy after login

This line of code retrieves the text content of the selected option.

For Selected Value:

var conceptName = $('#aioConceptName').find(":selected").val();
Copy after login

This line of code retrieves the value attribute of the selected option.

The reason why $("#id").val() fails in this scenario is that clicking on an option does not change the value of the dropdown itself. Instead, it merely adds the :selected property to the selected option, which is a child element of the dropdown.
