电台及电台组:

$(document).ready(function() {
    $(document).find("input:checked[type='radio']").addClass('bounce');   
    $("input[type='radio']").click(function() {
        $(this).prop('checked', false);
        $(this).toggleClass('bounce');

        if( $(this).hasClass('bounce') ) {
            $(this).prop('checked', true);
            $(document).find("input:not(:checked)[type='radio']").removeClass('bounce');
        }
    });
});

你可以使用JQuery来取消选中单选按钮

$('input:radio[name="IntroducerType"]').removeAttr('checked');
                $('input:radio[name="IntroducerType"]').prop('checked', false);

下面是jQuery的代码:

jQuery("input:radio").removeAttr("checked");

对于javascript:

$("input:radio").removeAttr("checked");

没有必要在foreach循环，.each()函数或任何东西

(纯js)

this.checked = false;

或(jQuery)

$(this).prop('checked', false);
// Note that the pre-jQuery 1.6 idiom was
// $(this).attr('checked', false);

请参阅jQuery prop()帮助页面，了解attr()和prop()之间的区别，以及为什么prop()现在更可取。 prop()是2011年5月在jQuery 1.6中引入的。

谢谢帕特里克，你让我今天很开心!你必须使用鼠标下键。不过，我已经改进了代码，以便您可以处理一组单选按钮。

//We need to bind click handler as well
//as FF sets button checked after mousedown, but before click
$('input:radio').bind('click mousedown', (function() {
    //Capture radio button status within its handler scope,
    //so we do not use any global vars and every radio button keeps its own status.
    //This required to uncheck them later.
    //We need to store status separately as browser updates checked status before click handler called,
    //so radio button will always be checked.
    var isChecked;

    return function(event) {
        //console.log(event.type + ": " + this.checked);

        if(event.type == 'click') {
            //console.log(isChecked);

            if(isChecked) {
                //Uncheck and update status
                isChecked = this.checked = false;
            } else {
                //Update status
                //Browser will check the button by itself
                isChecked = true;

                //Do something else if radio button selected
                /*
                if(this.value == 'somevalue') {
                    doSomething();
                } else {
                    doSomethingElse();
                }
                */
            }
    } else {
        //Get the right status before browser sets it
        //We need to use onmousedown event here, as it is the only cross-browser compatible event for radio buttons
        isChecked = this.checked;
    }
}})());

基于Igor的代码对Laurynas的插件进行了轻微修改。这容纳了与目标单选按钮相关的可能标签:

(function ($) {
    $.fn.uncheckableRadio = function () {

        return this.each(function () {
            var radio = this;
                $('label[for="' + radio.id + '"]').add(radio).mousedown(function () {
                    $(radio).data('wasChecked', radio.checked);
                });

                $('label[for="' + radio.id + '"]').add(radio).click(function () {
                    if ($(radio).data('wasChecked'))
                        radio.checked = false;
                });
           });
    };
})(jQuery);
