Uncaught TypeError: (intermediate value)(...) is not a function
当我在闭包中将 js 逻辑编写为单个 js 文件时，一切正常，如下所示：
(function(win){
//main logic here
win.expose1 = ....
win.expose2 = ....
})(window)
但是当我尝试在同一个 js 文件中的闭包之前插入一个日志记录替代函数时，
window.Glog = function(msg){
console.log(msg)
}
// this was added before the main closure.
(function(win){
//the former closure that contains the main javascript logic;
})(window)
它抱怨有一个TypeError：
Uncaught TypeError: (intermediate value)(...) is not a function
我做错了什么？
ajaxfileupload.js 报Uncaught TypeError: jQuery.handleError is not a function错误
因为“handleError”函数是在低版本的jquery 中的函数，所以解决方案是从低版本中的jquery 中找到这个函数
handleError: function( s,xhr,status,e ) {
// If a local callback was specified,fire it
if ( s.error ) {
s.error.call( s.context || s,e );
}
// Fire the global callback
if ( s.global ) {
(s.context ? jQuery(s.context) : jQuery.event).trigger( "ajaxError",[xhr,s,e] );
}
}
把这个函数加入ajaxfileupload.js中去，就不报错了。

angular-translate 报错 Uncaught TypeError: f.has is not a function

antd Upload上传报Uncaught TypeError: items.map is not a function错误
使用antd里面的Upload来上传文件，写好之后运行报错。。。
代码是这样的：
const uploadProps = {
action: createTheURL(''software/stu/score'', ''upload''),
method: ''POST'',
headers: {
authorization: tokenHandler.getSessionByKey(''authorization'')
},
onRemove: this.handleRemove
}
<Form.Item
label=''附件''
>{getFieldDecorator(''appendix'', {
initialValue: JSON.parse(appendix) || [],
valuePropName: ''fileList'',
})(<Upload {...uploadProps} >
<a style={{ marginRight: 20 }}>
<Icon type="plus" />添加附件
</a>
<span>(最多上传10个文件，单个文件不能超过20M)</span>
</Upload>)}
</Form.Item>造成这个问题的原因是，因为在上传了一个文件之后，会有产生一个新的fileList，但是这个新的fileList没有回传到Upload组件的fileList里面，所以只要我们把新的fileList给到Upload，那么这个问题就可以解决了。
最开始的做法是，将fileList存到state里面，然后每次上传文件就会触发Upload的onChange函数，在onChange函数里面使用setState将新的fileList包存到state里面，最后在将state里面的fileList放到Upload里面。
代码大概就是这个样子：
handleChange = info => {
const { fileList } = info;
this.setSate({
fileList
});
}
render(){
const { fileList } = this.state;
const uploadProps = {
action: createTheURL(''software/stu/score'', ''upload''),
method: ''POST'',
headers: {
authorization: tokenHandler.getSessionByKey(''authorization'')
},
fileList,
onRemove: this.handleRemove,
onChange: this.handleChange
};
return (
<Form.Item
label=''附件''
>
<Upload {...uploadProps} >
<a style={{ marginRight: 20 }}>
<Icon type="plus" />添加附件
</a>
<span>(最多上传10个文件，单个文件不能超过20M)</span>
</Upload>
</Form.Item>
)
}但是这样写，在后面还是会有一些问题，这里只用来处理新增表单数据没问题；但是如果是要对上传之后的表单数据进行一个修改的话就会出现问题。
因为在修改的时候，需要先获取已经提交了的数据，对于已经上传了的文件需要先获取到文件名，生成fileList存到state里面，然后再放到Upload组件里面，如果这样写的话，最后就会发现整个流程就很混乱，而且也不一定完全没问题。
最终解决办法：
直接使用antd Form组件里面的getValueFromEvent方法，这个方法的作用就是把onChange的参数回传到Upload里面(这里的参数就是file和fileList)。
antd Form组件
我写的代码如下：
const uploadProps = {
action: createTheURL(''software/stu/score'', ''upload''),
method: ''POST'',
headers: {
authorization: tokenHandler.getSessionByKey(''authorization'')
},
onRemove: this.handleRemove
}
<Form.Item
label=''附件''
>{getFieldDecorator(''appendix'', {
initialValue: JSON.parse(appendix) || [],
valuePropName: ''fileList'',
getValueFromEvent: e => {
if (Array.isArray(e)) {
return e;
}
return e && e.fileList;
}
})(<Upload {...uploadProps} >
<a style={{ marginRight: 20 }}>
<Icon type="plus" />添加附件
</a>
<span>(最多上传10个文件，单个文件不能超过20M)</span>
</Upload>)}
</Form.Item>
axios 源升级导致异常Uncaught TypeError: axios is not a function
问题现象
已经稳定运行近一年的项目，2022年10月7日10点，客户反馈，用户请求无法触发，怎么点都不好使~
查看请求日志，发现2022年10月7日凌晨1点多axios请求日志没有了。
定位
https://unpkg.com/axios/dist/axios.min.js 访问302，重定向到https://unpkg.com/axios@1.1.0/dist/axios.min.js。
导致客户端代码报错：Uncaught TypeError: axios is not a function...
https://unpkg.com/axios/dist/axios.min.js 之前的源码对应的是0.*.*版本，是可以直接在代码中使用 axions()对应api方法的。升级后，导致axios找不到。
解决方案
替换引入为：<script src="https://unpkg.com/axios@0.18.1/dist/axios.min.js"></script>
后话
unpkg官方这操作也太草率了吧~
