我試圖將導出列表導出爲csv。我使用daterangepicker來選擇日期，然後使用JQuery導出列表，但每當我按下導出按鈕的頁面刷新...在調試模式，我可以看到它通過代碼，但在結束的時候功能沒有任何反應......csv與jQuery導出
這裏是我的CoffeeScript代碼
# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://jashkenas.github.com/coffee-script/
if gon.current_controller == 'measurements'
$ ->
# Search functionality
$('form.measurement.search [name=daterange]').daterangepicker({
format: gon.js_formats.moment.date,
ranges: {
'Today': [moment(), moment()],
'Yesterday': [moment().subtract('days', 1), moment().subtract('days', 1)],
'Last 7 Days': [moment().subtract('days', 6), moment()],
'This Week': [moment().startOf('week'), moment().endOf('week')],
'Last Week': [moment().subtract('week', 1).startOf('week'), moment().subtract('week', 1).endOf('week')],
'Last 30 Days': [moment().subtract('days', 29), moment()],
'This Month': [moment().startOf('month'), moment().endOf('month')],
'Last Month': [moment().subtract('month', 1).startOf('month'), moment().subtract('month', 1).endOf('month')]
},
startDate: moment().subtract('days', 29),
endDate: moment()
},
(start, end) -> $('form.measurement.search').submit());
$('form.measurement input,select').change (ev) ->
$('form.measurement.search').submit()
$('form.measurement [name=clear]').click (ev) ->
$('form.measurement.search [name=daterange]').val('')
$('form.measurement.search').submit()
false
# CSV export
$('form.measurement [name=format_csv]').click (ev) ->
form = $(ev.target).closest('form')
$('[name=format]', form).val('csv').prop('disabled', false)
form.submit()
$('[name=format]', form).val('').prop('disabled', true)
false
這裏是我如何調用該函數：
<%= submit_tag "Export CSV", name: :format_csv, class: 'btn btn-default' %>
，這裏是我的控制器：
class MeasurementsController < ApplicationController
# GET /measurements
include MeasurementsHelper
def index
@channel_name = Channel.find(params[:channel_id]).try(:label)
@measurements = filter_measurements_by_params(Measurement.where(channel_id: params[:channel_id]).order('measured_at DESC'))
@users = User.select(:id, :username, :name)
@total = @measurements.length
@measurements = @measurements.paginate(page: params[:page], per_page: 50)
respond_to do |format|
format.html # index.html.erb
format.csv { render csv: @measurements }
end
end
def show
@measurement = Measurement.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: @measurement }
end
end
# GET /measurements/new
def new
@measurement = Measurement.new(channel_id: params[:channel_id])
respond_to do |format|
format.html # new.html.erb
end
end
# POST /measurements
def create
params[:measurement][:user_id] = current_user.id
params[:measurement][:channel_id] = params[:channel_id]
@measurement = Measurement.new(measurement_params_create)
respond_to do |format|
if @measurement.save
format.html { redirect_to channel_measurements_url(@measurement.channel), notice: 'Measurement was successfully created.' }
else
format.html { render action: "new" }
end
end
end
# DELETE /measurements/1
def destroy
@measurement = Measurement.find(params[:id])
channel = @measurement.channel
@measurement.destroy
respond_to do |format|
format.html { redirect_to channel_measurements_url(channel), notice: 'Measurement was successfully deleted.' }
end
end
private
def measurement_params_create
params.require(:measurement).permit(:value, :channel_id, :user_id, :measured_at)
end
end
我希望有人能幫助... ...
