javascript - Check/Uncheck using jQuery not working -

i trying make check boxes behave radio buttons in asp .net mvc web application. have got 20-30 check boxes grouped in two. example:

<input type="checkbox" id="@riggingtype.riggingtypeid 1" name="riggingtypeplus"         value="@riggingtype.riggingtypeid"         checked="@riggingtypeids.contains(riggingtype.riggingtypeid)" />  <input type="checkbox" id="@riggingtype.riggingtypeid 2" name="riggingtypeminus"         value="@riggingtype.riggingtypeid"         checked="@riggingtypeids.contains(riggingtype.riggingtypeid)" /> 

goal:

i want make check boxes behave in such way if plus check box checked minus unchecked automatically , vice versa. have written following code try , achieve functionality:

$(":checkbox").change(function () {   var inputs = $(this).parents("form").eq(0).find(":checkbox");   var idx = inputs.index(this);   if (this.name.substring(this.name.length - 4, this.name.length) === "plus") {       // trying check if getting right        // , getting right id       // alert(inputs[idx + 1].id);        // not work       $("#" + inputs[idx + 1].id).prop('checked', false);   } }); 

am doing wrong here:

$("#" + inputs[idx + 1].id).prop('checked', false); 

any appreciated.

i know can use radio buttons , group them same name rendering elements in loop have same name different values , don't want name them differently because using data on server side... there better way this?

answer:

got working using following:

$(document).ready(function(){     $(":checkbox").on('click', function () {      var $this = $(this);     var inputs = $this.closest("form").find(":checkbox");    if ($this.attr('name').substring(this.name.length - 4, this.name.length) === "plus" && $this.attr('checked')) {         $this.next().prop('checked', false);     }         else         {             $this.prev().prop('checked', false);         }   }); });
