I can't get my Dropdownlist to hide using a checkbox

 原文  2015-06-23 11:01:43  1   1    javascript/ c#/ jquery/ asp.net/ asp.net-mvc

Question

I have tried to get this to work but the code starts to hide the dropdownlist and shows it when I check the checkbox so far so good, but I can't figure out to hide it Again.

Can anybody help me with this. I am pretty new to MVC and jQuery. The code I have found on this site, but maybe somebody can tell me what I am doing wrong. Thanks

I think there could be a problem with following lines of code: 

    $('#compareadmin').click(function () {
        if (this.checked) {

Try to change it to: 

    $('#compareadmin').click(function () {
        if ($(this).is(':checked') {

Or this lines where you only need to provide id not the element selector as id is always unique on page or it must be unique if not: 

  else{
        $('select#ItemId2').hide("fast");
    }

change it to : 

  $('#ItemId2').hide("fast");

Try above things and let me know if don't work.
