How to clear radio button in Javascript?

Question

I have a radio button named "Choose" with the options yes and no. If I select any one of the options and click the button labeled "clear", I need to clear the selected option, using javascript. How can I accomplish that?

Answer 1

You don't need to have unique id for the elements, you can access them by their name attribute:

If you're using name="Choose", then:

• With jQuery it is as simple as:

  $('input[name=Choose]').attr('checked',false);
  

• or in pure JavaScript:

     var ele = document.getElementsByName("Choose");
     for(var i=0;i<ele.length;i++)
        ele[i].checked = false;

Answer 2

If you do not intend to use jQuery, you can use simple javascript like this

document.querySelector('input[name="Choose"]:checked').checked = false;

Only benefit with this is you don't have to use loops for two radio buttons

Answer 3

This should work. Make sure each button has a unique ID. (Replace Choose_Yes and Choose_No with the IDs of your two radio buttons)

document.getElementById("Choose_Yes").checked = false;
document.getElementById("Choose_No").checked = false;

An example of how the radio buttons should be named:

<input type="radio" name="Choose" id="Choose_Yes" value="1" /> Yes
<input type="radio" name="Choose" id="Choose_No" value="2" /> No

Answer 4

An ES6 approach to clearing a group of radio buttons:

    Array.from( document.querySelectorAll('input[name="group-name"]:checked'), input => input.checked = false );

Answer 5

Wouldn't a better alternative be to just add a third button ("neither") that will give the same result as none selected?

Answer 6

In my case this got the job done:

const chbx = document.getElementsByName("input_name");

for(let i=0; i < chbx.length; i++) {
    chbx[i].checked = false;
}
