我有一个Rails应用程序,其中包含表格中的潜在客户列表。在其中一个列中,我在下拉菜单中显示潜在客户的状态。我想在更改下拉列表中选择的值时启用更改潜在客户的此状态。
这就是我的尝试:
在表格单元格中显示表单的代码:
<% @leads.each do |lead| %>
<tr>
<td><%= lead.id %></td>
<td><%= form_for(lead,:url => 'update_lead_status') do |f| %>
<div class="field">
<%= f.select :status, ["to_call","called","confirmed","lite"], :selected => lead.status, onchange: "this.form.submit();" %>
</div>
<% end %>
</td>
引导控制器中的update_lead_status方法:
#PUT
def update_lead_status
@lead = Lead.find(params[:id])
respond_to do |format|
# format.js
if @lead.update_attributes(params[:lead])
format.html { redirect_to leads_url, notice: 'Lead was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @lead.errors, status: :unprocessable_entity }
end
end
end
此外,我希望提交为Ajax样式而不刷新。

设置表单ID,然后提交表单
<%= form_for(lead,:url => 'update_lead_status',:html=>{:id=>'lead_form'}) do |f| %>
<%= f.select :status, ["to_call","called","confirmed","lite"], :selected => lead.status, onchange: "$('#lead_form').submit();" %>
<% end %>
