Is there a way to determine the selected radio button using Node.js?

I'm currently working on a form that includes two radio buttons. I am posting the request and using the body parser npm package to retrieve the values of the form inputs. Here is how the radio buttons are implemented in the form:


    <p>
      <input class="with-gap" name="group1" type="radio" id="test1" />
      <label for="test1">Teacher</label>
    </p>
    <p>
      <input class="with-gap" name="group1" type="radio" id="test2" />
      <label for="test2">TA</label>
    </p>

However, when I try to log req.body, I only receive this information regarding the radio buttons:

{ group1: 'on' }

This doesn't indicate which specific radio button was selected. Even if I change one of their names to "group2", both can be selected simultaneously. How can I identify which radio button was clicked?

Answer №1

Ensure that the radio buttons have a designated value attribute as shown below:

<input class="custom-radio" name="options" type="radio" id="option1" value="value1"/>

This will allow the body-parser object to recognize the selection as {options: "value1"}.

Answer №2

To check if a checkbox is selected on the client side, you can utilize $('#id').prop( "checked" ). Alternatively, on the back end, you would access the value using req.body.name_of_input.
