JQuery 无法与我的 Rails 3.2 项目一起启动/工作
正如标题所示,我已确保所有需要的 JS 文件都包含在元标记中,包括 jquery-rails/coffee-rails gem,链接到外部文件以防万一。
这是来自 Ryan Bates Stripe 教程的修改脚本,据我了解,它应该通过检测表单中的提交操作来启动。
由于我对 JS 或 CoffeeScript 不太熟悉,所以我无法真正指出这里的问题是什么。
将不胜感激我能得到的任何帮助。
donations.js 文件:
jQuery ->
Stripe.setPublishableKey($('meta[name="stripe-key"]').attr('content'))
donation.setupForm()
donation =
setupForm: ->
$('#new_donation').submit ->
$('input[type=submit]').attr('disabled', true)
if $('#card_number').length
donation.processCard()
false
else
true
processCard: ->
card =
number: $('#card_number').val()
cvc: $('#card_code').val()
expMonth: $('#card_month').val()
expYear: $('#card_year').val()
Stripe.createToken(card, donation.handleStripeResponse)
handleStripeResponse: (status, response) ->
if status == 200
alert(response.id)
else
alert(response.error.message)
donations/new.html.erb 表单
<%= form_for(@donation) do |f| %>
<div class="field">
<%= f.label :from %>
<%= f.text_field :from %>
</div>
<div class="field">
<%= label_tag :card_number, "Credit Card Number" %>
<%= text_field_tag :card_number, nil, :name => nil %>
</div>
<div class="field">
<%= label_tag :card_code, "Security Code (CVV)" %>
<%= text_field_tag :card_code, nil, :name => nil %>
</div>
<div class="field">
<%= label_tag :card_month, "Card Expiration" %>
<%= select_month nil, {:add_month_numbers => true}, {:name => nil, :id => "card_month"} %>
<%= select_year nil, {:start_year => Date.today.year, :end_year => Date.today.year+15}, {:name => nil, :id => "card_year"} %>
</div>
<div class="field">
<%= f.label :Notes %>
<%= f.text_field :note %>
</div>
<br>
<center>
<span class="BigBold">Amount: $2.50</span>
<%= f.hidden_field :amount, {:value => "2,5" } %><br>
</center>
<br>
<center>
<%= f.submit "Donate Now", :class => 'donate-button' %>
</center>
<% end %>
As in the title, I`ve made sure all needed JS files are included in the meta tags, included the jquery-rails/coffee-rails gem, linked to a external one just in case.
This is a modified script from Ryan Bates tutorial on Stripe, from what I understand it`s suppose to fire up by detecting the submit action from the form.
Since I'm not that familiar with JS or CoffeeScript, I can't really pin point what's the problem here.
Would appreciate any help I can get.
The donations.js file:
jQuery ->
Stripe.setPublishableKey($('meta[name="stripe-key"]').attr('content'))
donation.setupForm()
donation =
setupForm: ->
$('#new_donation').submit ->
$('input[type=submit]').attr('disabled', true)
if $('#card_number').length
donation.processCard()
false
else
true
processCard: ->
card =
number: $('#card_number').val()
cvc: $('#card_code').val()
expMonth: $('#card_month').val()
expYear: $('#card_year').val()
Stripe.createToken(card, donation.handleStripeResponse)
handleStripeResponse: (status, response) ->
if status == 200
alert(response.id)
else
alert(response.error.message)
The donations/new.html.erb form
<%= form_for(@donation) do |f| %>
<div class="field">
<%= f.label :from %>
<%= f.text_field :from %>
</div>
<div class="field">
<%= label_tag :card_number, "Credit Card Number" %>
<%= text_field_tag :card_number, nil, :name => nil %>
</div>
<div class="field">
<%= label_tag :card_code, "Security Code (CVV)" %>
<%= text_field_tag :card_code, nil, :name => nil %>
</div>
<div class="field">
<%= label_tag :card_month, "Card Expiration" %>
<%= select_month nil, {:add_month_numbers => true}, {:name => nil, :id => "card_month"} %>
<%= select_year nil, {:start_year => Date.today.year, :end_year => Date.today.year+15}, {:name => nil, :id => "card_year"} %>
</div>
<div class="field">
<%= f.label :Notes %>
<%= f.text_field :note %>
</div>
<br>
<center>
<span class="BigBold">Amount: $2.50</span>
<%= f.hidden_field :amount, {:value => "2,5" } %><br>
</center>
<br>
<center>
<%= f.submit "Donate Now", :class => 'donate-button' %>
</center>
<% end %>

您的 javascript 似乎是,Coffeescript - 确保将其放入自己的
donations.js.coffee
文件中,并且您包含coffee- Rails
gem,当你在做的时候。标准调试技术在这里会很有用 - 尝试在初始
jQuery ->
行之后添加alert("It live!")
或其他内容,以查看 document.ready 是否已就绪处理程序一直被调用。如果没有,请检查以确保首先加载
donations.js.coffee
文件,如果没有,请确保您将其加载到页面的标头中,或者您已经在application.js
中是这样的:或者,如果您只想将所有内容包含在
app/assets/javascripts
中:Your javascript seems to be, well, Coffeescript - make sure it's put in its own
donations.js.coffee
file, and that you're including thecoffee-rails
gem while you're at it.Standard debugging techniques would be useful here - try adding an
alert("It lives!")
or something after the initialjQuery ->
line to see if the document.ready handler is ever being called.If not, check to make sure that the
donations.js.coffee
file is being loaded in the first place, and if not, make sure you're either loading it in your page's header, or you have something like this inapplication.js
:Or, if you just want to include everything in
app/assets/javascripts
:Peter 是对的,您的 CoffeeScript 代码应该正确命名,以便可以将其翻译为 JavaScript。
另一种调试策略是查看发送到浏览器的 html/js 源代码。使用view source命令查看html源代码。然后单击对包含翻译后的donations.js 的js 链接的引用。
Peter is correct, your coffeescript code should be properly named so that it can be translated to JavaScript.
An additional debugging strategy is to look at the html/js source being sent to your browser. Use the view source command to see the html source. Then click on the reference to the js link containing the translated donations.js.
