jQuery get value of selected radio button

📢Hey there! Trying to get the value of a selected radio button? I gotchu! 🎉

So you're facing a little issue here with a radio button group, where every radio button has the same ID, and you need to determine if a button is selected. But don't worry, I got a simple solution for you using jQuery. 💪

First, let's take a look at the sample code you provided. It seems that when a radio button is selected, it doesn't add a "checked" attribute to the control, but instead, it adds the text "checked." So, our goal is to check if the radio button contains the text "checked" and get its value. Easy peasy! 😎

Here's the jQuery code to solve your problem:

// Get the value of the selected radio button
var selectedValue = $(":radio[name='s_2_1_6_0']:checked").val();

// Check if a radio button is selected
if (typeof selectedValue !== "undefined") {
    // Hurray! A radio button is selected
    console.log("Selected value: " + selectedValue);
} else {
    // Oops! No radio button is selected
    console.log("No radio button selected");
}

In this code, we're using the :radio selector to target all radio buttons, then narrowing it down to only those with the name attribute equal to 's_2_1_6_0'. Finally, we use .val() to get the value of the selected radio button.

To check if any radio button is selected, we verify if the selectedValue is undefined or not. If it's not undefined, voila! A radio button is selected. Otherwise, we'll see the "No radio button selected" message.

💡 Remember to include jQuery in your web page before using this code. You can easily do it by adding the following script tag in your HTML:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

Now, you're all set! Go ahead and grab the value of that selected radio button. 🎉
