A radio button is a graphical control element that allows the user to choose only one of a set of options. When a radio button is clicked, it changes its state from “not checked” to “checked”.
By default, a radio button is not checked when the page loads. You can change this default by setting the checked property of the radio button to true.

There may be instances when you want a radio button to be checked by default. In this article, we will show you how to make a radio button checked by default in Windows and Mac.
Windows
To make a radio button checked by default in Windows, follow these steps:
1. Open the form that contains the radio buttons.
2. Select the radio button that you want to be checked by default.
3. Right-click the selected radio button and select Properties.
4. In the Properties window, go to the Checked default check box and select the check box.
5. Click the OK button.
Now, the selected radio button will be checked by default when the form is opened.
Mac
To make a radio button checked by default in Mac, follow these steps:
1. Open the form that contains the radio buttons.
2. Select the radio button that you want to be checked by default.
3. Control-click the selected radio button and select Get Info.
4. In the Get Info window, go to the Checked default check box and select the check box.
5. Click the OK button.
Now, the selected radio button will be checked by default when the form is opened.
When creating forms, you may use radio buttons to allow users to select one option from a list of choices. You can use the isRadioButtonChecked() method to determine whether a particular radio button is checked.
The following example demonstrates how to use the isRadioButtonChecked() method:
$radioButtons = array(“Yes”, “No”, “Maybe”);
if (isset($_POST[“radioButtons”]))
{
foreach ($_POST[“radioButtons”] as $value)
{
if (isset($radioButtons[$value]))
{
echo “The ” . $value . ” radio button is checked.”;
}
}
}
?>
This code will print whether or not the corresponding radio button is checked.
When creating forms, it’s important to make sure that the user’s input is accurate. One way to do this is to make sure that the user can only select one option from a list of choices. This is done using radio buttons.
To make sure that a radio button is checked, you can use the following code:
if (document.getElementById(“radio1”).checked) {
//code to run if radio button is checked
}
If you want to check if more than one radio button is checked, you can use the following code:
if (document.getElementById(“radio1”).checked ||
document.getElementById(“radio2”).checked) {
//code to run if either radio button is checked
}
A radio button is a type of input control that allows users to select one option from a set of pre-determined alternatives. By default, radio buttons are usually set to the “checked” state, which means that the selected option is already activated when the page loads.
If you want to change the default value of a radio button, you can do so by adding the “checked” attribute to the tag. For example, the following code will set the “My Radio Button” option to the checked state by default:
Alternatively, you can use the “value” attribute to set the default value of a radio button. For example, the following code will set the “My Radio Button” option to “1” by default:
Radio buttons are a type of form input that allow users to choose one option from a list. They are commonly used to ask a question with a limited number of possible answers.
When it comes to radio buttons, there are a few things to consider. One of those things is whether or not the buttons should have a default selection.
There are pros and cons to both options. Let’s take a look at them.
If radio buttons have a default selection, it means that the first option in the list is automatically chosen when the form is first filled out. This can be helpful for the user, as it means they don’t have to take the time to select an option themselves.
However, there is also the potential for the user to not notice that the default selection has been chosen and to not change it if they want to select a different option. This can lead to confusion and frustration on the part of the user.
If radio buttons don’t have a default selection, it means that the user has to select an option themselves. This can be more time-consuming for the user, but it also ensures that they are always selecting the option that they want.
There is no right or wrong answer when it comes to whether or not radio buttons should have a default selection. It depends on the individual form and the needs of the user.
If you’re unsure which option is best for your form, it’s a good idea to test both options and see which one is more user-friendly.
There may be many reasons why you would want to keep a radio button unchecked by default. Maybe you don’t want to receive certain types of notifications, or you’re not interested in a certain type of product. Whatever the reason, it’s easy to do.
In most cases, you can just leave the radio button unchecked and it will remain that way. However, if you’re using a form or survey, you may need to take a different approach.
In some cases, you can set the default value for a radio button using the HTML code. For example, you can use the checked attribute to set a default value.
In other cases, you may need to use JavaScript to set the default value. For example, you can use the following code to set the default value for a radio button.
var myRadio = document.getElementById(“myRadio”);
myRadio.defaultValue = “option1”;
In React, you can use the “checked” attribute to determine if a radio button is checked. If you want to determine whether a radio button is checked or not in your code, you can use the “isChecked” property.
