问题描述

我有一个表单，它在最终发布到它的 ACTION URL 之前执行了一些广泛的 Javascript 内容.我正在编写一些 Jasmine 单元测试，并希望确保在提交表单时发生 Javascript 内容.但是，我绝对不希望页面在我进行单元测试时转到 ACTION URL.

I have a form that does some extensive Javascript stuff before finally POSTing to it's ACTION URL. I am writing some Jasmine unit tests and want to make sure the Javascript stuff happens when the form is submitted. However, I definitely don't want the page to go to the ACTION URL while I am unit testing.

我在这里看到了一个不错的建议:http://groups.google.com/group/jasmine-js/browse_thread/thread/a010eced8db17c1a?pli=1

I saw what seemed like a good suggestion here: http://groups.google.com/group/jasmine-js/browse_thread/thread/a010eced8db17c1a?pli=1

...但是，由于我对 Jasmine 还很陌生，我不确定如何实现它，并且在网络上找不到任何相关的示例.有没有人有一些我可以查看的示例代码可以完成我的需要?

...but, as I am fairly new to Jasmine, I am unsure how to implement it and cannot find any pertinent examples on the web. Does anyone have some sample code I could look at that would accomplish what I need?

谢谢！

推荐答案

也许这个代码片段可以帮助你...

Maybe this code snippet can help you...

it('calls ajax post on export button click', function() {
  view.render();
  var form = $('#export_images_xml_form');
  var submitCallback = jasmine.createSpy().andReturn(false);
  form.submit(submitCallback);

  $('#export_images_xml_button').click();

  expect(form.attr('action')).toEqual('/export');
  expect($('#export_images_xml_form input').attr('value')).toEqual('22,33,44');
  expect(submitCallback).toHaveBeenCalled();
});

我所做的基本上是停止在关联回调中返回 false 的给定表单的每次提交(请参阅 submitCallback 行为).

What I do is basically stopping every submit for given form returning false in the associated callback (see submitCallback behavior).

那我也可以测试回调是否被调用...

Then I can also test callback has been called...
