基本上,我想提交一个创建新课程表单并使用 JQuery 处理响应。我的表格喜欢
<div id="create_coursem">
<%= form_tag({:controller => "coursem", :action => "create"}, :id => "check_coursem_form", :method => "post", :remote => true) do %>
<p>
<b> <%= label_tag(:name, "Name:") %> </b>
<%= text_field_tag(:name) %>
</p>
<p>
<b> <%= label_tag(:department, "Department:") %> </b>
<%= select_tag "department", @result.html_safe %>
</p>
<%= submit_tag("Create") %>
<% end %>
</div>
在我的控制器中,我有
def create
@coursem = Coursem.createCoursemByUser(params[:name], params[:department])
@errCode = @coursem
if @coursem.class != Fixnum
@errCode = 1
end
@dic = {:errCode => @errCode, :coursem => @coursem}
respond_to do |format|
format.json { render json: @dic}
end
end
响应状态为200,表示成功返回了一个json。在我的 JS 文件中,我有
$(document).ready(function() {
panelHandler();
//showOverview();
showResources();
resourceHandler();
calendarChangeMonth();
subscribeHandler();
shownewresourceform();
eventinfo();
closeeventbox();
showneweventform();
colorrecentevents();
check_coursem();
})
function check_coursem() {
$("form#check_coursem_form").on('ajax:beforeSend', function(xhr, settings) {alert("hello");})
.on('ajax:success', function(data, status, xhr) {alert("hello");})
.on('ajax:complete', function(xhr, status) {alert("hello");})
.on('ajax:error', function(xhr, status, error) {alert("hello");});
}
但是当我单击创建按钮时,它只返回创建控制器生成的 json,不显示任何警报。有谁知道原因吗?非常感谢。
