Hi,

I need to enable/disable dropdown on another dropdown selection. I wrote below code to do the same but its working fine on my system with all browser compatibility but not on other machine with IE8.
Please suggest .

C#

///enable disable Payment method dropdown on moneysource  dropdown change
if (stepName == "PaymentDetails") {
    $("select").each(function () {
        if ($(this).parent().attr("controlName") == "Money source") {
            $(this).change(function () {
                enableDisablePaymentMethod($(this));
            });
            enableDisablePaymentMethod($(this));
        }
    });
}

///enable disable Payment method dropdown on moneysource  dropdown change
function enableDisablePaymentMethod(dropdown) {
    var length = dropdown.children("option").length;
    var val = dropdown.val();
    $("select").each(function () {
        if ($(this).parent().attr("controlName") == "Payment method" || $(this).parent().attr("controlName") == "Payment Method") {
            if (length == 0 || val == "") {
                $(this).prepend('<option value="Select Money Form" selected="selected">Select Money Form</option.');
                $(this).attr("disabled", "disabled");
            }
            else {
                $(this).removeAttr("disabled");
                $(this).children("option[value='']").remove();
                $(this).children("option[value=Select Money Form]").remove();

            }
        }
    });
}

Please try this code

$('#ParentDD').change(function(){
var SelectedDD = $(this).val();
if(SelectedDD == "P1")
{
var x=document.getElementById("ChildDD");
    x.disabled=true;
}
else if(SelectedDD == "P2")
{
var x=document.getElementById("ChildDD");
    x.disabled=false;
}
});

This is not a solution, and posting it as such reduces the chances of you getting any help. Plus, it's 7 years old, so the chances of anyone who might help seeing it are very low.

Post it as a new question, but give us better detail than that, and copy'n'paste your code instead of linking offsite - the later makes the automated system think you might be a spammer and that delays the posting until a human volunteer (or me in this case) reviews the case.
