JavaScript javascript to get the value of a div if it has a class javascript class value change,javascript classlist value,javascript classname value,

I have two divs

<div class="tab-pane active" id="home">

<div class="tab-pane" id="profile">

Each of this div has forms in it which has a hidden field <input type="hidden" name="selectedRadioValue" id="selectedRadioValue">

So I would like to create a javascript which would assign a value to the hidden input field.

if($("#home").hasClass("active"))                               //Dont know whether this is  
                                                            // true
    {
      assign "radio1" as the value in the input hidden field //what could be the equvalent                                     
                                                             //  statement for this?
    }
else if($("#profile").hasClass("active"))
    {
     assign "radio2" as the value in the input hidden field  //what could be the equvalent                                     
                                                             //  statement for this?
    }

Im sorry for this kind of a question.Im new to javascript,so I have tried a little bit of statements myself,but I need help.How to accomplish this?Please help

Solution:

$(function () {
    $('button').on('click', function () {
        if ($("#home").hasClass("active")) {
            $('.selectedRadioValue').val('radio1');
        } else if ($("#profile").hasClass("active")) {
            $('.selectedRadioValue').val('radio2');
        }
    });
});
Answer:1

You need to loop through every tab pane that is active, then select form that is in that tab pane and then get hidden value in that form. Then set value that you get to radio button in that same form.

Also, it's not good to have multiple elements with same id like #selectedRadioValue. Consider using classes instead.

$(function() {
    // Loop through all active tab panes
    $('.tab-pane.active').each(function() {
        // Get hidden input value
        var hiddenValue = $('form #selectedRadioValue', $(this)).val();

        // Set radio input value to hidden input value
        // Radio inputs should have '.radio-input' class tho
        $('form .radio-input', $(this)).val(hiddenValue);
    });
});

Edit

Ohh, you need to assign hidden inputs to radio1/radio2? Then your code is correct and all you need to do is assign radio1/radio2 as the value of your input. Just add class like radio-hidden to it and then do $('.radio-hidden').val('radio1'); etc.

$(function () {
    $('button').on('click', function () {
        if ($("#home").hasClass("active")) {
            $('.radio-hidden').val('radio1');
        } else if ($("#profile").hasClass("active")) {
            $('.radio-hidden').val('radio2');
        }
    });
});

Answer:2
if($("#home").hasClass("active"))                              
{
  $("#selectedRadioValue").val("radio1");
}
else if($("#profile").hasClass("active"))
{
   $("#selectedRadioValue").val("radio2");
}

Should do what you want I think?
