Javascript code/ function to validate Radio Button | Check Radio button is checked

Introduction:

In my previous article I have explained about Code used to validate emailid using javascript. In this article I am going to explain about How to remove html tags from the input string

Explanation:

For explanation purpose I have two radio buttons with name “gender”. While clicking on the validate button I am checking whether any one gender is selected.

Below is the javascript code used to validate the radio button.

function fnCheckRadio(name) {

    var flag = "0";

    var objs = document.getElementsByName(name);

    if (objs) {

        if (objs.length > 0) {

            for (var i = 0; i < objs.length; i++) {

                if (objs[i].checked == true) {

                    alert("Selected Value is " + objs[i].value);

                    return;

                }

            }

            if (flag == "0") {

                alert("Radio button is not checked..");

            }

        }

    }

}

Here is the demo..
