茉莉花-错误：茉莉花固定装置需要在window.jQuery或window。$中定义jQuery。

Question

I am just learning and trying to test my javascript with Jasmine framework. 我只是学习并尝试使用Jasmine框架测试我的javascript。 My javascript is just setting placeholder attribute of textarea to blank. 我的JavaScript只是将textarea的占位符属性设置为空白。

function clearPlaceholderTextOnFocus(i) {
    i.placeholder = '';
}

I am calling this function on onClick event of textarea. 我在textarea的onClick事件上调用此函数。 I wrote below code in Jasmine spec- 我在Jasmine规范中写了以下代码-

describe("Test suite for clearPlaceholderTextOnFocus",function(){
it("Should set placeholder to blank", function(){

var i=affix('textarea[name="message"][placeholder="write your message here..."]');

clearPlaceholderTextOnFocus(i);

var placeholderval = $('i').attr('placeholder'); 
expect(placeholderval).toHaveValue('');
});

});

When I run this code by double clicking on SpecRunner.html then I am getting below error - 当我通过双击SpecRunner.html运行此代码时，出现以下错误-

Error: jasmine-fixture requires jQuery to be defined at window.jQuery or window.$ 错误：茉莉花夹具需要在window.jQuery或window。$处定义jQuery。

Below is my SpecRunner.html file : 以下是我的SpecRunner.html文件：

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>Jasmine Spec Runner v2.5.2</title>

  <link rel="shortcut icon" type="image/png" href="lib/jasmine-2.5.2/jasmine_favicon.png">

  <!-- include spec files here...  -->
  <script src="spec/myfirstSpec.js"></script> 

</head>
<body>
</body>
</html>

What is wrong with my spec code? 我的规范代码有什么问题？ or do i need any other setup to run this? 还是我需要任何其他设置来运行此程序？

Did you import Jquery in your SpecRunner.html? 您是否在SpecRunner.html中导入了Jquery？ Like this 像这样

 <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/core.js"></script>
