我正在开发一个Ruby on Rails的2.3.8应用程序,我想知道如何提交 remote_form_for
的形式,当用户preSS的内ENTER键textarea的。
I'm developing a Ruby On Rails 2.3.8 application and I would like to know how to submit a remote_form_for
form when users press the ENTER key within the textarea.
下面的格式code:
<% remote_form_for :post, PostComment.new, :url => save_outside_comment_path(post_id), :html => { :method => :put} do |f| %>
<%= f.text_area :comment, :rows => 1, :id => "txtOutsideComment_#{post_id}", :class => "new-reply-text" %>
<% end %>
下面是jQuery的功能,它一提交,但不AJAX:
Here is the jQuery function that does a submit, but not AJAX:
jQuery('.new-reply-text').keypress(function(e) {
if (e.keyCode == 13 && !e.shiftKey) {
e.preventDefault();
this.form.submit();
}
});
我已经做了页面更新,从我的控制器,我不希望指定一个像成功的任何语法:从这个jQuery函数
。我只是希望它提交 remote_form_for
使用AJAX。
I already do the page update from my controller, do I don't want to specify any syntax like success:
from this jQuery function. I just want it to submit the remote_form_for
using AJAX.
我觉得你问如何做一个AJAX请求,而不是一个完整的页面提交。如果是这样
I think you're asking how to do an AJAX request instead of a full page submit. If so
jQuery('.new-reply-text').keypress(function(e) {
if (e.keyCode == 13 && !e.shiftKey) {
e.preventDefault();
jQuery.ajax({
url: "/my/URL",
data: jQuery(this).form.serialize(),
success: function(){},
dataType: "json"
});
}
});
如果您使用可以保存几个参数,不用彷徨 http://api.jquery.com/jQuery.get/
You can save a few parameters if you use .get http://api.jquery.com/jQuery.get/
或.POST http://api.jquery.com/jQuery.post/
其中包装了阿贾克斯 http://api.jquery.com/jQuery.ajax/
Which are wrappers for .ajax http://api.jquery.com/jQuery.ajax/
我不是一个轨道的人,所以你需要更新的第一个jQuery对象的类/ id来找到 remote_form_for
I'm not a rails guy so you'll need to update the class/id of the first jQuery object to find the remote_form_for
