I'm new to Rails and AJAX and am stuck at how I can update a Rails table from a Javascript function with AJAX.
我是Rails和AJAX的新手，我一直纠结于如何用AJAX从Javascript函数中更新Rails表。
Specifically, I am working on a planner and when I drop a draggable div (this represents an item in my database) onto a calendar, I'd like to change the 'start date' for that item. I can retrieve the correct date upon placement, I just don't know how to update the Rails table variable with this new date.
具体地说，我正在处理一个计划器，当我将一个draggable div(它表示数据库中的一个项目)放到一个日历中时，我想要更改这个项目的“开始日期”。我可以在放置时获取正确的日期，我只是不知道如何使用这个新日期更新Rails表变量。
Normally, I would access it as: batch_ticket.start_date.
通常，我将以如下方式访问它:batch_ticketter .start_date。
From what I've seen, I need to make a remote AJAX call to update this variable but I'm stuck on how to do this. Any push in the right direction would be fantastic. Thanks!
根据我所看到的，我需要做一个远程AJAX调用来更新这个变量，但是我还是不知道怎么做。任何朝着正确方向的努力都将是不可思议的。谢谢!

checkout the :remote => true option available for rails forms. also look into creating an *.js.erb file which will be rendered back to the browser and executed after the remote form is submitted.
签出:remote => true选项，可用于rails表单。同时也要考虑创建一个*.js。erb文件，该文件将在提交远程表单后返回浏览器并执行。
