我怎样才能触发一次切换?
我有......
<%= f.check_box :push %>
<label for="challenge_push" class="reminder-choices">Push</label>
<%= f.check_box :message %>
<label for="challenge_message" class="reminder-choices">Text</label>
<%= f.check_box :mail %>
<label for="challenge_mail" class="reminder-choices">Email</label>
<script>
$('.reminder-choices').click(function(){
$(".hide-remind").toggle();
});
</script>
我试过......
# Same behavior as above. Still toggles back and forth.
$('.reminder-choices').one("click", function(){
$(".hide-remind").toggle();
});
换句话说,单击.reminder-choices
一次后,切换将起作用,否则如果再次单击它则无效。

你的第二次尝试应该有效。你也可以这样做。
$('.reminder-choices').on('click.reminder', function() {
$(".hide-remind").toggle();
$(this).off('click.reminder');
});
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="reminder-choices">Click Here</div>
<div class="hide-remind">Will be toggled</div>
&#13;
修改:如果您有多个元素,并希望在点击其中一个元素后忽略所有元素的点击次数:
$('.reminder-choices').on('click.reminder', function() {
$(".hide-remind").toggle();
$('.reminder-choices').off('click.reminder');
});
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="reminder-choices">Click Here</div>
<div class="reminder-choices">Or Here</div>
<div class="reminder-choices">Or Here</div>
<div class="hide-remind">Will be toggled</div>

将代码包装在容器中,然后委派事件。
$('.container').one('click', '.reminder-choices', function() {
$(".hide-remind").toggle();
});
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="reminder-choices">Click Here</div>
<div class="reminder-choices">Or Here</div>
<div class="reminder-choices">Or Here</div>
</div>
<div class="hide-remind">Will be toggled</div>
