Question

My JQuery function looks like, where a$RadioBtn is the one only radio button list on my form:

IR.Web.cRptCtl.prototype.getSelectedRadioValue = function(a$RadioBtn){
  //Here I want to return a$RadioBtn's selected value
}

How do I determine the selected value?

Answer 1

If a$RadioBtn is a JQuery object of the radio elements, use:

a$RadioBtn.filter(":checked");

This will return a JQuery object, representing the selected radio input field. If you want to perform DOM operations on it, use the .get(0) method to get the DOM element.

Example:

IR.Web.cRptCtl.prototype.getSelectedRadioValue = function(a$RadioBtn){
    var selected = a$RadioBtn.filter(":checked");
    alert(selected.val());
}
