What is the best method to extract the string value from a dropdown menu?

Please help me obtain the value from a dropdown list correctly. I am using the Django-widget-tweaks library.

Here is the code for the dropdown list field from which I want to retrieve the string value:

<p >{{ form.category_column.label_tag }}</p>
<p id="category_column_id">{% render_field form.category_column  autocomplete="off" hx-get="/sizescolumn/" hx-target="#id_sizes_column" %}</p>

I have attempted to extract the value using JavaScript with this line of code:

var select = document.getElementById('category_column_id').value;

Note: I need the string value from this dropdown list field to compare it with another string value.

--->Unfortunately, so far it has not been successful. Thank you in advance.

Answer №1

If you want to retrieve the string value of the selected item, use .innerHTML instead of .value

var selectedItem = document.getElementById("yourId").innerHTML;

Answer №2

The id attribute 

id="category_column_id"
has been added to the <p> tag.

It is important to note that id attributes should be unique on a page, unlike classes which can be used multiple times. If there is another element with the same id 'category_column_id', the <p> tag may be selected first by your javascript code. Since a <p> tag does not have a value like a select column does, your javascript may not return any results.

To resolve this issue, check the id of your select element on the page and ensure it matches the id used in your javascript code. As long as you are using the correct id and there is only one instance of it, there should not be any issues with your javascript code in modern browsers.

Answer №3

Just wanted to express my gratitude for the solution provided below:

        let selectedCategory = $('#id_category_column').find(":selected").text();

I believe this tip could be beneficial for others down the line.
