在rails上我将所有JavaScript文件放入应用程序js文件中.
//= require jquery
//= require jquery_ujs
//= require dropzone
//= require jquery.cookie
//= require toastr
//VENDOR JS BEGINS
//= require pace/pace.min
//= require modernizr.custom
//= require jquery-ui/jquery-ui.min
//= require boostrapv3/js/bootstrap.min

//= require jquery-bez/jquery.bez.min

//= require bootstrap-datepicker/js/bootstrap-datepicker
然后我在application.html.erb的头部调用javascript作为;

<head>
..
<%= javascript_include_tag 'application' %>
..
</head> …我有一个日期时间选择器，它通过搜索框发送签入和签出日期。然后，URL看起来像；
http://localhost:3000/locations/listings?utf8=%E2%9C%93&search=london&start_date=12%2F04%2F16&end_date=20%2F04%2F16
然后我将params散列并解析字符串，
start_date = Date.parse(params[:start_date])
end_date = Date.parse(params[:end_date])
首先，我必须检查一下 if (start_date.present? && end_date.present?)，并且工作正常。
但是，如果用户手动键入其他内容而不是日期，例如；
http://localhost:3000/locations/listings?utf8=%E2%9C%93&search=london&start_date=londoneye6&end_date=20%2F04%2F16
然后，我当然会出错。
invalid date
我应该如何控制字符串是否可在控制器操作中解析。我还应该检查london-eye, london/eye字符串，其中包括- /
谢谢
我使用引导日期选择器从和到输入字段。当查询参数不为空时，我想更改这些输入字段的值并在 datepicker 上触发更改日期事件，因为我有一个计算日期之间总价的函数。当用户从 datepicker 选择日期时工作正常，但如果我通过 jquery 更改值，它不会计算。
$('#from').val('<%= @from_date %>').trigger( 'change' );
$('#to').val('<%= @to_date %>').trigger( 'change' );
//function
var dates_avail = new DatesAvailability({
start: '#from',
end: '#to'
});
..
W.DatesAvailability = function (opts) {
var options = $.extend({}, defaultOpts, opts);
var start = options.start + ',' + options.rel_start;
var end = options.end + ',' + options.rel_end;
$(start + ',' + end).datepicker({
autoclose: true,
format: "yyyy-mm-dd",
startDate: '+1d',
endDate: '+3y',
..
}).
on('changeDate', function (e) {

@house = (House.all).uniq.where("business_model like ?", "sleep")
我试过那段代码.仅当列只是"睡眠"时它才有效.当它"清醒,睡觉"时,它返回零.
这是为什么？
我有一系列哈希.
arr =[{:code=>"404", :demo => "1"}, {:code=>"302", :demo => "1"}, {:code=>"200", :demo => "1"}]
我想将其转换为:
[["404", "1"], ["302", "1"], ["200", "1"]]
我试过了:
arr.each do |a|
puts a.values
end
但这只创建了一个数组;
["404", "1", "302", "1", "200", "1"]
