php - jQuery 浏览器兼容性 (IE)

Question

由于我试图向您展示的源代码相当长且复杂，因此我只是提供一个指向我遇到问题的页面的链接。

http://www.thesportinghub.com/lms/make-my-picks

如果您在 Google Chrome 或最新版本的 Firefox(5 或 6)中使用此脚本，您会注意到此脚本中的 jQuery 是如何工作的。它完全按照我希望的方式在这些浏览器中工作。

但是，我目前无法弄清楚为什么它在 IE6、IE7 和 IE8 中无法正常工作...我愿意对 IE6 说“无论如何”，但我真的希望让它能够在 IE6 中正常工作IE7 和 IE8。通过查看我的源代码，您可以看到是否有任何内容导致了 IE7 和 IE8 中的问题。

主要问题(在 Chrome 和 IE 中使用 jQuery 后你会注意到)是，当单击一个团队时，它将禁用输入字段，并在其余时间对该团队进行删除几周的时间。但是，在 IE 中正确禁用输入，但罢工(jQuery 中的 addClass)不起作用。

我愿意提供更多信息......我还不想重载信息。但这是我几个小时以来一直在努力解决的问题。

预先感谢您的帮助。我会接受最佳答案并投票!谢谢!

代码更新如下

这是我当前的 javascript/jquery 代码:

<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>

如上所述，访问我发送给大家的附加链接(上面)可能更容易，并尝试先在 Chrome 中查看代码(并且看看它是如何工作的，如我期望的那样工作)，然后在 IE 6 - IE 8 中尝试它，并注意它并没有完成我想要它做的所有事情。

期待您能为我提供的所有帮助!

更新

$('input[disabled]:not(:checked)').next('span').addClass('strike');

我认为上面的代码是我的问题出现的地方...让我的属性在 IE 中无法正确读取有什么奇怪的吗？

Answer 1

您需要正确关闭输入标签。

<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 似乎足够聪明，可以修复它并处理 </input>作为前一个输入元素的一部分，但如果您尝试此 jsfiddle在IE中，你可以看到它认为</input>是下一个标签。 $("foo").next("span")仅当下一个元素是跨度时才会选择它。
