问题
Since the source code I am trying to show you is rather long and complex, I am simply going to provide a link to the page I am having troubles with.
http://www.thesportinghub.com/lms/make-my-picks
If you work with this script in Google Chrome or the latest versions of Firefox (5 or 6), you will notice how the jQuery in this script is intended to work. It works exactly how I want it to work in those browsers.
However, I am currently having trouble figuring out why it is not working correctly in IE6, IE7, and IE8... I am willing to say "whatever" to IE6, but I am really hoping to get this to work in IE7 and IE8. By viewing my source code, is there anything you can see that is causing the problems in IE7 and IE8.
The main issue (as you will notice after you play with the jQuery in Chrome, and then in IE), is that when a team is clicked, it will disable the input field and put a strike through that team throughout the rest of the weeks. However, the input is disabling correctly in IE, but the strike (addClass in jQuery) is not working.
I am willing to provide more information.... I don't want to overload info quite yet. But this has been an issue I have been struggling to fix for a few hours now.
Thank you in advance for your help. I will accept the best answer and vote up! Thanks!
UPDATES WITH CODE ARE BELOW
Here is my current javascript/jquery code:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('.radio:checked').addClass("selected");
$('.pickbox').text($('.radio:checked').val());
var selected_week = $('#weekselect').val();
$('table.weekbox').hide();
$('table#weekbox' + selected_week).show();
$('span.selection.text').html('<br/>My Week ' + selected_week + ' Selection:');
$('input.radio').change(function () {
$('.teambox').find('span.strike').removeClass('strike');
var selected = $(this).val();
var us_selected = selected.replace(/ /g, "");
$('.radio:not(:checked)').removeClass('selected');
$('.radio:not(:checked)').next('span').css('color', '');
$('.radio:not(:checked)').removeAttr('disabled');
$('.radio:checked').addClass('selected');
$('.pickbox').text($(this).val());
$('.pickbox').css('border', '3px dashed #88cc33');
//$('.pickbox').text($('.teambox').find('span.' + us_selected).text());
$('.teambox').find('span.' + us_selected).addClass('strike');
$('.selected').each(function () {
var selected_team = $(this).val();
var x_selected_team = selected_team.replace(/ /g, "");
$('.teambox').find('span.' + x_selected_team).text(selected_team).addClass('strike');
$('table.weekbox').find('td input[value="' + selected_team + '"]').attr('disabled', 'disabled');
$('.selected').next('span').css('color', '#88cc33');
});
});
$('#weekselect').change(function () {
var selected_week = $('#weekselect').val();
if ($('input[name="Week' + selected_week + '"]').is(':not(:checked)')) {
$('table.weekbox').hide();
$('table#weekbox' + selected_week).show();
$('span.selection.text').html('<br/>My Week ' + selected_week + ' Selection:');
$('.pickbox').css('border', '1px dashed #FFFFFF');
$('.pickbox').text('');
}
$('table.weekbox').hide();
$('table#weekbox' + selected_week).show();
$('span.selection.text').html('<br/>My Week ' + selected_week + ' Selection:');
$('input:not(:checked)').next('span').removeClass('strike');
$('input[disabled]:not(:checked)').next('span').addClass('strike');
$('.pickbox').text($('input.radio[name="Week' + selected_week + '"].selected').val());
if ($('.pickbox').text() != "") {
$('.pickbox').css('border', '3px dashed #88cc33');
}
$('.selected').each(function () {
var selected_team = $(this).val();
var x_selected_team = selected_team.replace(/ /g, "");
$('.teambox').find('span.' + x_selected_team).text(selected_team).addClass('strike');
});
});
});
</script>
Here is some of the DOM elements this jQuery should be affecting:

As mentioned above, it is probably easier to visit the attached link (above) I have sent you all and try to look at the code first in Chrome (and see how it works how I expect it to work), and then try it in IE 6 - IE 8 and notice how it does not do everything I am wanting it to do.
Look forward to all the help you can provide me!
UPDATE
$('input[disabled]:not(:checked)').next('span').addClass('strike');
I think the above code is where my problem is coming up... is there something funky about making my attributes not read correctly in IE?
回答1:
You need to close your input tags correctly.
<input type="radio" class="radio" name="Week1" value="New York Jets"></input> //Incorrect
<input type="radio" class="radio" name="Week1" value="New York Jets" /> //Correct
Chrome seems to be smart enough to fix it and treat the </input> as part of the previous input element, but if you try this jsfiddle in IE, you can see it thinks </input> is the next tag. $("foo").next("span") will only select the next element if it is a span.
