Question

Function:

function disable_hidden_flip_questions(option, value){
    var first_q = document.getElementById('hidden_auto_questions');
    var second_q = document.getElementById('hidden_include_auto');
    var inputs_list = [];
    if(option == 'all'){
        inputs_list.push(first_q.getElementsByTagName("input"));
        inputs_list.push(second_q.getElementsByTagName("input"));
    }else if (option == 'first'){
        inputs_list.push(first_q.getElementsByTagName("input"));
    }else if(option == 'second'){
        inputs_list.push(second_q.getElementsByTagName("input"));
    }

    for (var inputs in inputs_list){
        for(var input in inputs_list[inputs]){
            if(inputs_list[inputs].hasOwnProperty(input) && input != 'length'){
                if(!value){
                    inputs_list[inputs][input].removeAttribute('disabled');
                }else{
                    inputs_list[inputs][input].setAttribute("disabled", "disabled");
                }
            }
        }
    }
}

Works perfectly fine in Chrome and Firefox, but in IE9 the console gives me an error on this line:

inputs_list[inputs][input].setAttribute("disabled", "disabled")

If I console.log(inputs_list[inputs][input]) I get this in Chrome:

(The input is being generated by RoR, which is why its name and id are so long)

<input class="radio_buttons optional" id="custom_attributes_trailer_insurance_endorsement_false" name="custom_attributes[trailer_insurance_endorsement]" type="radio" value="false" disabled="disabled"> 

Yay, that’s what I wanted (and expected)… But in IE9’s console I get this:

[object HTMLCollection]

Which is completely useless….

So question: Where am I going wrong in IE’s exalted view? I know IE9 supports setAttribute, so I am assuming it has to do with my for...in loops.

Edit: So due to comments, the problem could be with the object types (HTMLCollection being stored in an Array) . If that is indeed the case, how do I go about making everything compatible data types?

Solution in jquery:

  $("input[name=trailer_use]").click(function(event){
        if(event.target.id == "trailer_use_yes"){
            $("#hidden_auto_questions").removeClass('hide_auto').addClass('show_auto');
            $("input[name=trailer_insured]").removeAttr("disabled");
            show_trailer_warning(null, "remove");
        }else {
            $("#hidden_auto_questions").removeClass('show_auto').addClass('hide_auto');
            $("input[name=trailer_insured]").attr("disabled", "disabled");
            if($("#hidden_include_auto").hasClass("show_auto")){
                $("#hidden_include_auto").removeClass('show_auto').addClass('hide_auto');
                $('input[name="custom_attributes[trailer_insurance_endorsement]"]').attr("disabled", "disabled");
            }
            show_trailer_warning(null, "disclaimer");
        }
  });
