如果用户单击复选框,则下面的代码将会触发,但复选标记有时会消失,因此应在选中该复选框时未勾选。消失的复选标记的奥秘
$(document).on("page:change", function() {
$(".habit-check").change(function()
{
habit = $(this).parent().siblings(".habit-id").first().attr("id");
level = $(this).siblings(".level-id").first().attr("id");
if($(this).is(":checked"))
{
$.ajax(
{
url: "/habits/" + habit + "/levels/" + level + "/days_missed",
method: "POST"
});
}
else
{
$.ajax(
{
url: "/habits/" + habit + "/levels/" + level + "/days_missed/1",
method: "DELETE"
});
}
});
});
# I ALSO TRIED USING LOCAL STORAGE, BUT IT HAD THE SAME PROBLEM.
# VERSION 2
$(document).on("page:change", function() {
{
$(".habit-check").change(function()
{
habit = $(this).parent().siblings(".habit-id").first().attr("id");
level = $(this).siblings(".level-id").first().attr("id");
if ($(this).is(":checked")) {
$.ajax({
url: "/habits/" + habit + "/levels/" + level + "/days_missed",
method: "POST"
});
localStorage.setItem("habit_"+habit+"_"+level, true);
} else {
$.ajax({
url: "/habits/" + habit + "/levels/" + level + "/days_missed/1",
method: "DELETE"
});
localStorage.setItem("habit_"+habit+"_"+level, false);
}
});
});
调用AJAX
<div class="strikes">
<% if @habit.current_level_strike %>
<div class="btn" id="red"> <label id="<%= @habit.id %>" class="habit-id">Strikes:</label>
<% else %>
<div class="btn" id="gold"> <label id="<%= @habit.id %>" class="habit-id-two">Strikes:</label>
<% end %>
<% @habit.levels.each_with_index do |level, index| %>
<% if @habit.current_level >= (index + 1) %>
<p>
<% if @habit.current_level_strike %>
<label id="<%= level.id %>" class="level-id">Level <%= index + 1 %>:</label>
<% else %>
<label id="<%= level.id %>" class="level-id-two">Level <%= index + 1 %>:</label>
<% end %>
<%= check_box_tag nil, true, level.missed_days > 0, {class: "habit-check"} %>
<%= check_box_tag nil, true, level.missed_days > 1, {class: "habit-check"} %>
<%= check_box_tag nil, true, level.missed_days > 2, {class: "habit-check"} %>
</p>
<% end %>
<% end %>
</div>
</div>
的显示页这就是AJAX大火于days_missed_controller.rb。
class DaysMissedController < ApplicationController
before_action :logged_in_user, only: [:create, :destroy]
def create
habit = Habit.find(params[:habit_id])
habit.missed_days = habit.missed_days + 1
@habit.save!
level = habit.levels.find(params[:level_id])
level.missed_days = level.missed_days + 1
if level.missed_days == 3
level.missed_days = 0
level.days_lost += habit.calculate_days_lost + 1
end
level.save!
head :ok # this returns an empty response with a 200 success status code
end
def destroy
habit = Habit.find(params[:habit_id])
habit.missed_days = habit.missed_days - 1
habit.save!
level = habit.levels.find(params[:level_id])
level.missed_days = level.missed_days - 1
level.save!
head :ok # this returns an empty response with a 200 success status code
end
end

我也遇到了这个问题,当我删除turbolinks认为可能是问题,但事实并非如此。
单击复选框时是否触发页面加载? – fylooi
此外,尝试将'page:change'更改为'page:load' – fylooi
您可以尝试为复选框设置唯一的名称,可能是因为某些浏览器在单击名称相同的名称时会更改复选框的状态。 – jfornoff
