复选框更改功能仅触发一次

Question

Admittedly awful but trying to improve my jQuery skills and struggling with this issue. I have a few checkboxes that are being generated from an asp.net repeater, I'm trying to enforce only having one of these checkboxes checked at a time. I can get this working on jsFiddle but not in my solution, can anyone see anything that sticks out as being wrong?

JSFiddle

jQuery:

$(document).ready(function () {
     $('.menuBox input[type=checkbox]').change(function () {
        $('.menuBox input[type=checkbox]').not(this).prop('checked', false);
    });
});

HTML (generated by asp.net code):

<div class="menuBox">
   <div class="col1">
    <ul>
        <li id="ctl00_liCategory" class="liCategory">
            <input id="ctl00_chkCategory" type="checkbox" name="ctl00$chkCategory" onclick="javascript:setTimeout('__doPostBack(\'ctl00$chkCategory\',\'\')', 0)" />
            <label for="ctl00_chkCategory" id="ctl00_lblCategory">first label</label>
        </li>
        <li id="ctl01_liCategory" class="liCategory">
            <input id="ctl01_chkCategory" type="checkbox" name="ctl01$chkCategory" onclick="javascript:setTimeout('__doPostBack(\'ctl01$chkCategory\',\'\')', 0)" />
            <label for="ctl01_chkCategory" id="ctl01_lblCategory">second label</label>
        </li>
        <li id="ctl02_liCategory" class="liCategory">
            <input id="ctl02_chkCategory" type="checkbox" name="ctl02$chkCategory" onclick="javascript:setTimeout('__doPostBack(\'ctl02$chkCategory\',\'\')', 0)" />
            <label for="ctl02_chkCategory" id="ctl02_lblCategory">third label</label>
        </li>
    </ul>
   </div>    
</div>

ASP.NET code generating the html:

<div class="col1">
   <ul>
      <asp:Repeater runat="server" ID="rptrCategoriesCol1"    OnItemDataBound="rptrCategories_ItemDataBound">
         <ItemTemplate>
            <li runat="server" id="liCategory" class="liCategory">
               <asp:Checkbox runat="server" ID="chkCategory" AutoPostBack="true" OnCheckedChanged="FilterResults" CssClass="CategoryChkBox" />
               <asp:Label runat="server" ID="lblCategory" AssociatedControlID="chkCategory" />
            </li>
         </ItemTemplate>
      </asp:Repeater> 
   </ul>
</div>

Answer 1

If you are using a repeater, why not use a set of radio buttons instead, as you can only have one checked by default.

The only thing you will need is all of the inputs to have the same name

<input type="radio" name="list1" value="1"/>
<input type="radio" name="list1" value="2"/>
<input type="radio" name="list1" value="3"/>
<input type="radio" name="list1" value="4" />
<input type="radio" name="list1" value="5"/>

http://jsfiddle.net/314jm9oc/

$('.cbox').click(function() {
    $('.cbox').prop("checked",false);
    $(this).prop("checked",true);
});

Is a simple version of your checkbox issue, if you stick with checkbox's

$('.menuBox input[type=checkbox]').attr('onclick','');
$('.menuBox input[type=checkbox]').click(function() {   
   $('.menuBox input[type=checkbox]').prop("checked",false);
    $(this).prop("checked",true);
});

Will fit your provided example.

Haven't used .net webforms in a while. But if you add

OnClick="JavaScript:EnableDisable(this);"

To your checkbox's

<script type="text/javascript">
function EnableDisable(ele) {
   $('.menuBox input[type=checkbox]').each(function() {
     $(this).prop("checked",false");
   });
   ele.checked = true;
}
</script>

Answer 2

Try this on the blank html and it should work just like in jsFiddle

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>

<script>
$(function(){
  $('.menuBox input[type=checkbox]').change(function () {
    $('.menuBox input[type=checkbox]').not(this).prop('checked', false);
  });
}); 
</script>

<div class="menuBox">
<div class="col1">
<ul>
    <li id="content_0_rptrCategoriesCol1_ctl00_liCategory" class="liCategory">
        <input id="content_0_rptrCategoriesCol1_ctl00_chkCategory" type="checkbox" name="content_0$rptrCategoriesCol1$ctl00$chkCategory" onclick="javascript:setTimeout('__doPostBack(\'content_0$rptrCategoriesCol1$ctl00$chkCategory\',\'\')', 0)" />
        <label for="content_0_rptrCategoriesCol1_ctl00_chkCategory" id="content_0_rptrCategoriesCol1_ctl00_lblCategory">first label</label>
    </li>
    <li id="content_0_rptrCategoriesCol1_ctl01_liCategory" class="liCategory">
        <input id="content_0_rptrCategoriesCol1_ctl01_chkCategory" type="checkbox" name="content_0$rptrCategoriesCol1$ctl01$chkCategory" onclick="javascript:setTimeout('__doPostBack(\'content_0$rptrCategoriesCol1$ctl01$chkCategory\',\'\')', 0)" />
        <label for="content_0_rptrCategoriesCol1_ctl01_chkCategory" id="content_0_rptrCategoriesCol1_ctl01_lblCategory">second label</label>
    </li>
    <li id="content_0_rptrCategoriesCol1_ctl02_liCategory" class="liCategory">
        <input id="content_0_rptrCategoriesCol1_ctl02_chkCategory" type="checkbox" name="content_0$rptrCategoriesCol1$ctl02$chkCategory" onclick="javascript:setTimeout('__doPostBack(\'content_0$rptrCategoriesCol1$ctl02$chkCategory\',\'\')', 0)" />
        <label for="content_0_rptrCategoriesCol1_ctl02_chkCategory" id="content_0_rptrCategoriesCol1_ctl02_lblCategory">third label</label>

        <label for="content_0_rptrCategoriesCol2_ctl00_chkCategory" id="content_0_rptrCategoriesCol2_ctl00_lblCategory">fourth label</label>
    </li>
    <li id="content_0_rptrCategoriesCol2_ctl01_liCategory" class="liCategory">

        <label for="content_0_rptrCategoriesCol2_ctl01_chkCategory" id="content_0_rptrCategoriesCol2_ctl01_lblCategory">fifth label</label>

        <label for="content_0_rptrCategoriesCol3_ctl01_chkCategory" id="content_0_rptrCategoriesCol3_ctl01_lblCategory">seventh label</label>
    </li>
 </ul>

Your code works on JFiddle because, since you set Framework & extensions option to jQuery 1.7.2 , it's included inside a $(document).ready(...); statement. In order it to work everywhere you only have to do the same on your own:

$(document).ready(function() {
     $('.menuBox input[type=checkbox]').change(function () {
          $('.menuBox input[type=checkbox]').not(this).prop('checked', false);
     });
});
