我尝试使用jquery切换div-基本上是想隐藏表单的一部分,只有当用户选择特定的复选框时才显示它。
现在,我有下面的代码,它工作得很好,但不能弄清楚编辑它的内容和位置,以便与复选框而不是链接一起使用。另外,我不喜欢使用ID。
下面是示例代码:

.answer { display:none; }

$("a.question").click(function(){
 $(this).next(".answer").toggle();
}); 

<a href="#" class="question">Queston 1</a>
<div class="answer">Answer 1</div>

<a href="#" class="question">Queston 2</a>
<div class="answer">Answer 2</div>

任何帮助都将非常感谢,因为这是驾驶我坚果!

});

怎么样:

<input class="check" type="checkbox" >
<div class="answer">Answer 1</div>

<input class="check" type="checkbox" >
<div class="answer">Answer 2</div>​
<style type="text/css">
.answer { display:none; }
.check:checked+.answer{
display:block;
}
​
</style>

试试这个

.answer { display:none; }​

<input type="checkbox" class="question" /> : Queston 1
<div class="answer">Answer 1</div>

<input type="checkbox" class="question" /> : Queston 2
<div class="answer">Answer 2</div>​

    $(".question").click(function() {
        if ($(this).is(':checked')) {
            $(this).next(".answer").show();
        }
        else{
            $(this).next(".answer").hide();
        }
    });​
