无法读取未定义的'fn'属性? [英] Cannot read property of 'fn' of undefined?

问题描述

在我的github页面上获取这些错误代码.我将这些作为加载脚本的顺序:

 < script src ="../../node_modules/jquery/dist/jquery.js"</script>< script src ="../../js/bootstrap.min.js"></script>< script src ="../../js/index.js"></script> 

以下是错误消息:

 获取https://tmolano.github.io/CareerMod4/node_modules/jquery/dist/jquery.js 404()index.html:115 GET https://tmolano.github.io/CareerMod4/node_modules/popper.js/dist/popper.min.js 404()util.js:56未捕获的TypeError:无法读取未定义的属性'fn'在util.js:56在util.js:10在bootstrap.min.js:6在bootstrap.min.js:6(匿名)@ util.js:56(匿名)@ util.js:10(匿名)@ bootstrap.min.js:6(匿名)@ bootstrap.min.js:6 

此处显示我的页面: https://tmolano.github.io/CareerMod4/

除了加载顺序之外，还有什么可能导致这种情况?

解决方案

此错误的可能原因:

未捕获的TypeError:无法读取未定义的属性'fn'

1. 对文件地址的引用无效或文件丢失(您的情况).
2. 对Jquery的重复引用.
3. 在第三方库中重写Jquery的$符号.
4. 在插入Jquery之前使用Jquery函数(不是您的情况).
5. 在jquery中对WINDOW元素使用不推荐的语法进行加载，错误和卸载，而无需 on

Getting these error codes on my github pages. I have these as my order of loading scripts:

<script src="../../node_modules/jquery/dist/jquery.js"></script>
<script src="../../js/bootstrap.min.js"></script>
<script src="../../js/index.js"></script>

Here are the error messages:

GET https://tmolano.github.io/CareerMod4/node_modules/jquery/dist/jquery.js 404 ()
index.html:115 GET https://tmolano.github.io/CareerMod4/node_modules/popper.js/dist/popper.min.js 404 ()

Heres my page: https://tmolano.github.io/CareerMod4/

Other than the order of loading, what else could be causing this?

解决方案

Possible reasons for this error:

Uncaught TypeError: Cannot read property 'fn' of undefined

1. invalid reference to the file addresses or missing files (Your case).
2. Duplicate reference to the Jquery.
3. Overriding $ sign of Jquery in 3rd party libraries.
4. Using Jquery functions before inserting Jquery (Not your case).
5. Using deprecated syntax for load,error,unload on WINDOW element in jquery without on
