Here Mudassar Ahmed Khan has explained with an example, how to implement OnClick event of HTML RadioButton using JavaScript.
For illustration purposes, when the RadioButton is clicked based on whether it is checked (selected) or unchecked (unselected), a JavaScript function will be called within which the HTML DIV with TextBox will be shown or hidden. The HTML Markup consists of two RadioButtons (one for Yes and other for No) and an HTML DIV consisting of a TextBox.

This will make the text “Yes” and “No” as clickable labels for their radio buttons. The user can click the label to select the radio button. You’re probably thinking of action= for the form element. onClick would just fire a javascript function. More here: http://www.w3schools.com/jsref/jsref_onClick.asp
When to use onClick event in JavaScript?
For illustration purposes, when the RadioButton is clicked based on whether it is checked (selected) or unchecked (unselected), a JavaScript function will be called within which the HTML DIV with TextBox will be shown or hidden. In this article I will explain with an example, how to implement OnClick event of HTML RadioButton using JavaScript.
The client-side click event of decorated HTML input element of type “radio” or “checkbox” is not fired when the following conditions are met at the same time. The input is followed by a label element and there is not a whitespace between them. The “for” attribute of the label element and the “id” attribute of the input element are not declared.
How is a radio button rendered in JavaScript?
The problem here is that the rendering of a RadioButtonList wraps the individual radio buttons (ListItems) in span tags and even when you assign a client-side event handler to the list item directly using Attributes it assigns the event to the span. Assigning the event to the RadioButtonList assigns it to the table it renders in.
