我有一个带有提交按钮<%= f.submit "Create Meeting", class: "btn-submit" %>
的表单,该表单将收集的信息发送到我的事件控制器中的events#create
操作。
我希望能够在提交表单中的其他信息的同时向控制器操作发送javascript / JQuery数组idList
。我该怎么做呢?我知道它涉及AJAX功能,但我不知道何时调用它。我是否必须在Javascript中覆盖提交功能?如果是这样,那怎么办?
以下是我创建表单的方式:
<%= form_for(@newevent) do |f| %>
...
<%= f.submit "Create Meeting", class: "btn-submit" %>
<% end %>
这是我提交的控制器操作:
def create
@calendar = current_customer.calendar
@newevent = @calendar.events.build(event_params)
if @newevent.save
redirect_to '/main' #'/main/#{@calendar.id}'
else
redirect_to '/compose'
end
end
非常感谢任何帮助,谢谢
编辑:这是关于我的数组的javascript。当用户从集合中选择一个人时,选择&#34;同事 - 选择&#34;,将所选人员的id添加到该阵列中。用户也可以通过其他点击操作删除ID。
var idList = []; //this is the array of entry ids
$(function (){
$("#click-me").click(function (e){
e.preventDefault();
i++;
var list = $("#list");
var name = $("#colleague-select option:selected").text();
var id = $("#colleague-select").val();
var remove = "<button type='button' class='remove-me'> X </button>";
var entry = $("<li>" + name + remove+ "</li>").attr('id',id); //creates entry as JQuery object and sets its id attribute
list.append(entry); //adds entry to HTML element 'list'
idList.push(id); //adds id to array which should be the same as entry's id
return false;
});
});
$(document).on('click', ".remove-me", function(){
var entry = $(this).parent();
var id = entry.attr("id"); //gets value of attribute "id".
entry.remove();
var index = idList.indexOf(id); //finds the index number of id within array
idList.splice(index,1); //removes id from array
});
答案 0 :(得分:1)
根据您要发送的ID,您可以使用存储ID的隐藏字段:
<%= form_for(@newevent) do |f| %>
# ...
<%= hidden_field_tag 'some_ids[]', [1,2,3], id: 'extra_ids' %>
<%= f.submit "Create Meeting", class: "btn-submit" %>
<% end %>
然后在params
:
def create
some_ids = params[:some_ids]
# ...
end
使用您的Javascript进行设置:
$(function (){
$("#click-me").click(function (e){
# [...]
idList.push(id); //adds id to array which should be the same as entry's id
$('#extra_ids').val(idList);
return false;
});
});
$(document).on('click', ".remove-me", function(){
# [...]
idList.splice(index,1); //removes id from array
$('#extra_ids').val(idList);
});
