未捕获的TypeError：$（…）.easyAutocomplete不是函数
[英]Uncaught TypeError: $(…).easyAutocomplete is not a function
问题描述
I am creating a web app using Node js and express. 
我正在使用Node js和express创建一个Web应用程序。 For autocomplete I am using a third party node module called easy-autcomplete . 对于自动完成功能，我正在使用名为easy-autcomplete的第三方节点模块。 I have followed the documentation and included all the files however I am getting the following error 我已按照文档进行操作，并包含了所有文件，但是出现以下错误
Uncaught TypeError: $(...).easyAutocomplete is not a function
at HTMLDocument.<anonymous> (post-property.js:289)
at mightThrow (jquery-3.3.1.js:3534)
at process (jquery-3.3.1.js:3602)
post-property.js 后property.js
$(function(){
let countries = [
{"name": "Afghanistan", "code": "AF"},
{"name": "Albania", "code": "AL"},
{"name": "Algeria", "code": "DZ"},
..
..
]
var options = {
data: countries,
getValue: "name",
list: {
match: {
enabled: true
}
}
};
$("#provider-json").easyAutocomplete(options);
});
post-property.hbs 后property.hbs
<div class="row">
..
..
</div>
<script src="/javascripts/post-property.js"></script>
<script src="/scripts/jquery.easy-autocomplete.min.js"></script>
<link rel="stylesheet" href="/scripts/easy-autocomplete.css">
<link rel="stylesheet" href="/scripts/easy-autocomplete.themes.min.css">
app.js app.js
...
app.use('/scripts', express.static(__dirname + '/node_modules/easy-autocomplete/dist/'));
...
I checked for various solutions where I had to move my file from the node modules folder however the error persisted. 我检查了各种解决方案，必须将文件从节点模块文件夹中移出，但错误仍然存在。

You should move the script and css for easy-autocomplete before your own script. 您应该在自己的脚本之前将脚本和CSS移至易于自动完成的位置。
let countries = [ {"name": "Afghanistan", "code": "AF"}, {"name": "Albania", "code": "AL"}, {"name": "Algeria", "code": "DZ"}, ] var options = { data: countries, getValue: "name", list: { match: { enabled: true } } }; $("#basics").easyAutocomplete(options);
<head> <link rel="stylesheet" href="/scripts/easy-autocomplete.css"> <link rel="stylesheet" href="/scripts/easy-autocomplete.themes.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/easy-autocomplete/1.3.5/jquery.easy-autocomplete.min.js"></script> <script src="/javascripts/post-property.js"></script> </head> <body> <div class="row"> <input id="basics" /> </div> </body>
Then don't forget to include jQuery script as mentionned in the documentation 然后别忘了包含文档中提到的jQuery脚本

You need to load the plugin / library before your custom code, otherwise it won't exist. 您需要在自定义代码之前加载插件/库，否则它将不存在。 jQuery also needs to be included before both of these scripts . 在这两个scripts之前还需要包含jQuery 。
Try the following: 请尝试以下操作：
<script src="/scripts/jquery.easy-autocomplete.min.js"></script>
<script src="/javascripts/post-property.js"></script>
