关闭slideToggle时如何重置选定的单选按钮? [英] How to reset selected radio buttons when closing slideToggle?

问题描述

我有一个简单的slideToggle设置，可以在页面上打开一个div.有些div包含自检功能.我在弄清楚div关闭时如何重置单选按钮时遇到麻烦.这是jQuery:

I have a simple slideToggle setup that opens a div on a page. Some of the divs have a self test in them. I'm having trouble figuring out how to reset the radio buttons when the div is closed. Here is the jQuery:

$("h2.titleTrigger").click(function(e){
e.preventDefault();

//TOGGLE OPEN/CLOSE THE DIV
$(this).toggleClass("active").next().slideToggle("fast");
return false;
});


//self test

$('input:radio').bind('change',function(e){
e.preventDefault();
var parentId = $(this).parents('.selfTest').attr('id');
$('#'+parentId+' .selfTestWrong').addClass('answerShown');
$('#'+parentId+' .selfTestAnswer').slideDown(300);
});

当用户关闭slideToggle时，将自检重置为未选择状态的最佳方法是什么?

What is the best way to reset the self test to it's un-selected state when the user closes the slideToggle?

推荐答案

您可以执行以下操作:

$("h2.titleTrigger").click(function (e) {
    e.preventDefault();

    //TOGGLE OPEN/CLOSE THE DIV
    $(this).toggleClass("active").next().slideToggle("fast");

    // Re-set all the radio buttons
    $('input:radio').prop('checked', false);

    // Re-set all the labels class
    $('.selfTestWrong').removeClass('answerShown');
    return false;
});
