我在从控制器获取一些数据后尝试通过 js.erb 渲染部分内容时遇到问题。我已经尝试了很多不同的东西,我就是无法渲染部分。日志文件显示带有 200 OK 消息的部分呈现,但页面上没有任何反应。这篇文章与我遇到的问题类似:
我试图按照这篇文章的指导进行操作,但我仍然遇到问题。
这是我的部分表格 _ _left_date_filter.html.erb =>
<%= form_tag({:controller => 'events', :action => 'dateFilter'}, :class => 'date_form', :remote => true) do %>
<%= datepicker_input "event", :start_date, :class => 'dateFilter', :dateFormat => 'mm/dd/y' %>
<%= datepicker_input "event", :end_date, :class => 'dateFilter', :dateFormat => 'mm/dd/y' %>
<%= submit_tag "Submit" %>
<% end %>
这是生成的HTML =>
<form accept-charset="UTF-8" action="/events/dateFilter" class="date_form" data-remote="true" method="post">
<div style="margin:0;padding:0;display:inline">
<input name="utf8" type="hidden" value="✓" />
<input name="authenticity_token" type="hidden" value="x4cbSoYnUu2+W6qvtPnKXvXR8Tp3Yh7BP9W0RMyR02g=" /></div>
<input class="dateFilter" id="event_start_date" name="event[start_date]" size="30" type="text" /><script type="text/javascript">
//<![CDATA[
jQuery(document).ready(function(){jQuery('#event_start_date').datepicker({"dateFormat":"mm/dd/y"})});
//]]>
</script>
<input class="dateFilter" id="event_end_date" name="event[end_date]" size="30" type="text" /><script type="text/javascript">
//<![CDATA[
jQuery(document).ready(function(){jQuery('#event_end_date').datepicker({"dateFormat":"mm/dd/y"})});
//]]>
</script>
<input name="commit" type="submit" value="Submit" />
这是dateFilter.js.erb =>
$('#content').html("<%= escape_javascript(render(:partial => 'dateFilter')) %>");
这是events_controller =>
def dateFilter
eventIn = params[:event]
start_date = Date.parse(eventIn[:start_date])
end_date = Date.parse(eventIn[:end_date])
sql = *redacted*
@events = Event.find_by_sql(sql)
respond_to do |format|
format.html
format.json
format.js
end
end
这是application.js =>
$(document).ready(function() {
$('#date_form').submit(function (){
$.ajax({
type: 'POST',
url: "/events/dateFilter",
beforeSend: function (xhr) {xhr.setRequestHeader("Accept", "text/javascript");},
data: { 'start_date' : $("input[name='event[start_date]']").datepicker(), 'end_date' : $("input[name='event[end_date]']").datepicker()}
success: function(data) { $('#content').html(response); }
});
});
这是来自服务器的日志数据=>

最后,我希望呈现的页面 _dateFilter.html.erb =>
<div class="content">
<table class="table table-striped table-hover">
<thead>
<tr>
<th><%= sortable "event_id" %></th>
<th><%= link_to "Time Created", :sort => "event_date_time_local" %></th>
<th><%= link_to model_class.human_attribute_name(:event_type_id), :sort => "event_type" %></th>
<th><%= link_to model_class.human_attribute_name(:severity_id), :sort => "severity_name" %></th>
<th><%= link_to "Examined", :sort => "event_examined" %></th>
<th><%= link_to model_class.human_attribute_name(:action_required), :sort => "action_required" %></th>
<%#<th><%= model_class.human_attribute_name(:comments) </th>%>
<th><%= link_to model_class.human_attribute_name(:initials), :sort => "initials" %></th>
<th><%= link_to "Ticket ID", :sort => "taskid" %></th>
</tr>
</thead>
</div>
我只是不确定为什么它告诉我它正确呈现了部分,但是我的页面上没有任何反应。我对 JQuery 不是很熟悉,所以我的 application.js 或 datefilter.js.erb 文件中可能有问题。
