有时这个AJAX会发生火灾。有时它没有，让我解释一下。
habit.js
$(document).ready(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"
});
}
});
});
它只在我加载显示页面并刷新后触发，以便终端看起来像这样：

habit.missed_days = habit.missed_days + 1

这可能是Turbolinks的问题，您可以尝试更改您的javascript：
$(document).ready(function()
{
// ...
}
看起来像：
$(document).on("ready page:load", function() {
// ..
}
请告诉我它是否有帮助！
祝你好运！答案 1 :(得分：1)
根据我的评论，将我视为一个缓存问题。
首先要做的是Ajax方法，将缓存设置为false。然后，要查看它是否有效，请在成功处理程序中记录一些内容。这将向您展示Ajax确实已经解雇，但也会报告结果：
// nested in your code as per your sample; just extracted out here
$.ajax({
cache: false,
url: "/habits/" + habit + "/levels/" + level + "/days_missed",
method: "POST",
success: function(data){
console.log("result of Post is: ", data);
}
});
// ...
$.ajax({
cache: false,
url: "/habits/" + habit + "/levels/" + level + "/days_missed/1",
method: "DELETE",
success: function(data){
console.log("result of Delete is: ", data);
}
});
要做的补充是在浏览器中打开Web开发工具并检查网络活动。在进行Ajax调用时，它应该报告它花了多长时间以及源是什么。如果它来自缓存，它会在那里的某处说“缓存”。
答案 2 :(得分：1)
还没有那么多答案，但对于评论来说太大了。让我们看看是否实际上正在调用ajax。我放了一些警告框以及一个ajax错误捕手。运行它，看看你得到了什么行为。它应该有助于我们所有人了解真正发生的事情。
$(document).ready(function()
{
$(document).on("click", ".habit-check", function()
{
alert(".habit-check change called");
habit = $(this).parent().siblings(".habit-id").first().attr("id");
level = $(this).siblings(".level-id").first().attr("id");
if($(this).is(":checked"))
{
alert("calling POST " + "/habits/" + habit + "/levels/" + level + "/days_missed");
$.ajax(
{
url: "/habits/" + habit + "/levels/" + level + "/days_missed",

});
}

$.ajax(
