如何从之前选择的删除单选按钮检查属性？

Question

我有一些单选按钮，我将选中的属性添加到选定的单选按钮，但有一个问题。我想从选中的单选按钮中删除checked =“checked”属性。

HTML代码：

rxx = new Regex(@"(?<=<p\b[^<]*>).*?(?=</p>)");
var reslt2 = rxx.Matches("<p><someURL></p><p><anotherURL></p>").Cast<Match>().ToList();

jQuery代码：

<div class="tabtwo-info">
    <div class="tab-two">
        <div class="col-lg-4 col-md-4 col-sm-4 ">   <a class="brokersector" href="javascript:void(0);">
                <input type="radio" value="" id="" name="brokersector">
                <div class="image-cat-box">

Answer 1

在检查新内容之前强行删除属性：

$(".brokersector").click(function () {
    $('input[type=radio]').removeAttr('checked');
    $(this).find('input[type=radio]').attr('checked', 'checked');
});

在设置新收音机之前，这将强制删除任何单选按钮上的所有checked。选择器当然可以更具体，就像在Idir的例子中一样。

另外，@ Regent posted a fiddle使用prop代替。我建议你使用它，正如文档中所述：

  

尽管如此，要记住关于checked属性的最重要的概念是它与checked属性不对应。该属性实际上对应于defaultChecked属性，应该仅用于设置复选框的初始值。 checked属性值不会随复选框的状态而改变，而checked属性则会改变。

Answer 2

试试这个，

$(".tabtwo-info .brokersector").click(function() {
  $('input[name=brokersector]').removeAttr('checked');
  $(this).find('input:radio').attr('checked', 'checked');
});

Answer 3

我同意[Rory McCrossan] [1]，你不需要jQuery。但是你可以做到这一点：

$('input[name=brokersector]:checked').removeAttr('checked');

Answer 4

$(".tabtwo-info .brokersector").click(function () {
$("input:radio").removeAttr("checked");
    $(this).find('input:radio').attr('checked', true);
});


});
