没有涡轮链接的AJAX之后在rails中触发js [英] firing js in rails after AJAX with no turbolinks
问题描述
我有一个rails4应用程序.由于我不太擅长js，因此我关闭了TURBOLINKS.我已经阅读了很多文章，但仍然无法弄清楚如何组织我的javascript文件.目前，我在AJAX追加后触发js代码时遇到问题.
I have a rails4 app. Since I'm not good at js yet I TURNED OFF TURBOLINKS. I have read a bunch of articles, still I couldn't figure it out how to organize my javascript files. At the moment I have a problem with firing js code after AJAX append.
我有一个任务列表(索引页).如果我加载页面，那么我可以单击任何任务(以更新它们)，并且引导程序模式会显示+以下代码正在运行，因此时间已格式化，并且datetimepicker可用.
I have a list of tasks (index page). If I load the page then I can click on any of the tasks (to update them) and the bootstrap modal shows up + the following code is working, so the time is formatted and datetimepicker is available.
如果我使用AJAX创建新任务(将由create.js.erb追加)，然后单击该特定任务，则会显示模式，但不会触发以下代码. (如果我单击其余任务，则自页面加载以来，这些任务就按原样工作.)
If I create a new task with AJAX (will be appended by create.js.erb) and then click on that certain task the modal shows up but the following code doesn't get fired. (If I click on the rest of the tasks, those are working as they are there since page load.)
如何使它正常工作?我想让代码也可以在页面加载和页面更改时使用.由于这是用户触发的事件，因此希望不会触发两次. sby可以为我推荐一个清晰的很好的解释/文章如何组织我的js文件吗?正如我上面提到的，我读了很多，但是我变得更加困惑.
How can I make this working? I want to have the code to be available on page load and page change as well. Since this is a user triggered event hopefully doesn't get fired twice. Can sby recommend me a clear good explanation/article how I should organize my js files? As I mentioned above I read a bunch of them but I just got even more confused.
js文件
var ready = function() {
$('.updatetask').on('shown.bs.modal', function (e) {
alert('haha');
var modalId = $(this).attr('id');
var deadlineField = $("#" + modalId).find($('.edit-task-deadline'));
var deadlineValue = $(deadlineField).attr('value');
var momentDeadline = moment(deadlineValue).format('MM/DD/YYYY hh:mm A');
$(deadlineField).val(momentDeadline);
});
$(function () {
$('.new-task-deadline').datetimepicker({
sideBySide: true,
format: 'MM/DD/YYYY hh:mm A',
stepping: 15,
widgetPositioning: { vertical: 'bottom' }
});
});
};
$(document).ready(ready);
$(document).on("page:load", ready);

<% end %>
其他代码:
这是我用于新任务的示例代码(这很容易，因为只有一个模态而没有ID.)
Here is the sample code I'm using for new task (it's easier since there is just one modal with no ID.)
我希望它既可以用于文档更新也可以用于AJAX添加的代码进行更新.必须使用模式ID而不是表单ID来调用Submit.
I'd like to have it for updates as well both on document ready and AJAX added code. Submit must be called on the modal id not the form id.
新任务的工作代码:
$('.new-task-submit').on('click', function (e){
e.preventDefault();
var localMoment = moment($('.new-task-deadline').val());
$('.new-task-deadline').val(localMoment.toISOString());
$('#newtask').submit();
});
我尝试执行更新任务:
edit_task_submit($(document.body));
.....
......
function edit_task_submit($container) {
$container.find('.edit-task-submit').on('click', function (e){
e.preventDefault();
var deadlineField = $(this).find($('.edit-task-deadline'));
var localMoment = moment((deadlineField).val());
deadlineField.val(localMoment.toISOString());
alert(deadlineField.val());
$(this).submit();
});
}
update.js.erb
update.js.erb
<% else %>
$('ul.errors').hide();
$('.alert-danger').hide();
$('#updatetask_<%= @task.id %>').modal('hide');
$task = $('<%= j render @task %>');
edit_task_submit($task);
$('#task_<%= @task.id %>').fadeOut(400, function(){
$(this).remove();
//$(".newtaskinsert").prepend('<%= j render @task %>');
$(".newtaskinsert").prepend('$task');
$(".newtaskinsert2").prepend('<%= j render partial: "tasks/task_between", locals: { task: @task } %>');
});
<% end %>
推荐答案
$(document).ready在加载页面时执行一次. create.js.erb创建不应用此功能的新元素.
$(document).ready executed once, when the page is loaded. create.js.erb creates new elements, for which this function is not applied.
重新组织代码，如下所示:
Reorganize your code as follows:
js文件:
function updatetask($container)
{
$container.find('.updatetask').on('shown.bs.modal', function (e)
{
var deadlineField = $(this).find('.edit-task-deadline');
var deadlineValue = deadlineField.val();
var momentDeadline = moment(deadlineValue).format('MM/DD/YYYY hh:mm A');
deadlineField.val(momentDeadline);
});
}
function new_task_deadline($container)
{
$container.find('.new-task-deadline').datetimepicker({
sideBySide: true,
format: 'MM/DD/YYYY hh:mm A',
stepping: 15,
widgetPositioning: { vertical: 'bottom' }
});
}
$(function () // shortcut for $(document).ready
{
updatetask($(document.body));
new_task_deadline($(document.body));
});
create.js.erb:
create.js.erb:
$("ul.errors").html("");
<% if @task.errors.any? %>
//modal error messages get inserted via AJAX
$('.alert-danger').show();
$('ul.errors').show();
<% @task.errors.full_messages.each do |message| %>
$("ul.errors").append($("<li />").html("<%= message.html_safe %>"));
<% end %>
<% else %>
//hiding modal on creation and setting values to zero for optional new modal
$('ul.errors').hide();
$('.alert-danger').hide();
$("#newtask").modal('hide');
$(".task_name_company").val('');
$(".contentarea").val('');
$(".new-task-deadline").val('');
// time formatting and datetimepicker for new elements
$task = $('<%= j render @task %>');
updatetask($task);
new_task_deadline($task);
//different div class for different partials + table rows get inserted into view via AJAX
$(".newtaskinsert").prepend($task);
$(".newtaskinsert2").prepend('<%= j render partial: "tasks/task_between", locals: { task: @task } %>');
$("#task_<%= @task.id %>").hide().fadeIn(1000);
<% end %>
有关更新:
edit_task_submit($(document.body));
function edit_task_submit($container)
{
$container.find('.edit-task-submit').on('click', function (e)
{
e.preventDefault();
var $this = $(this);
var deadlineField = $this.closest('form').find('.edit-task-deadline');
var localMoment = moment(deadlineField.val());
deadlineField.val(localMoment.toISOString());
$this.click();
});
}
update.js.erb:
update.js.erb:
<% else %>
$('ul.errors').hide();
$('.alert-danger').hide();
$('#updatetask_<%= @task.id %>').modal('hide');
$task = $('<%= j render @task %>');
edit_task_submit($task);
$('#task_<%= @task.id %>').fadeOut(400, function()
{
$(this).remove();
$(".newtaskinsert").prepend($task);
$(".newtaskinsert2").prepend('<%= j render partial: "tasks/task_between", locals: { task: @task } %>');
});
<% end %>
