[英]JQuery issue "TypeError: $.getJSON is not a function"
I've got this piece of code:我有这段代码:
$(document).ready(function () {
$.getJSON('http://localhost:5000/', function (response) {
console.log(response);
});
});
localhost:5000 is a flask/python
script that returns a json
like: localhost:5000 是一个
flask/python
脚本,它返回一个json
,如:
{
"data": [
0,
0,
0,
And I'm getting:我得到:
$.getJSON is not a function TypeError: $.getJSON is not a function
Any tips where I can start untangling the whoolball?有什么技巧可以让我开始解开排球吗?
Thanks!谢谢!

lib/main.js
is where the document.ready
is located. lib/main.js
是document.ready
所在的位置。
Thanks!谢谢!
You seem to be using slim
version of jquery
which does not have the method getJSON
thats why you are getting this error.您似乎使用的是
slim
的jquery
版本,它没有getJSON
方法,这就是您收到此错误的原因。
Please use the full version of jquery
instead from the below link.请使用以下链接中的完整版
jquery
代替。
https://code.jquery.com/jquery-3.1.1.min.js https://code.jquery.com/jquery-3.1.1.min.js
Slim
version of jquery
excludes ajax
, animations effects
etc Slim
版jquery
不包括ajax
、 animations effects
等
Thus happens commonly when migrating codebases from jQuery v1.x+ to v3.0+ as jQuery updated/deprecated/discontinued some of it's API.因此,在将代码库从 jQuery v1.x+ 迁移到 v3.0+ 时经常发生这种情况,因为 jQuery 更新/弃用/停止了它的一些 API。
I recommend using jQuery Migrate which will address this, along with other issues:我建议使用 jQuery Migrate 来解决这个问题以及其他问题:
Get it here via CDN:通过 CDN 在此处获取:

If using Gulp/Grunt, you can import into your project using如果使用 Gulp/Grunt,您可以使用导入到您的项目中
npm install --save jquery jquery-migrate

function cinta(){
$.getJSON('http://localhost:5000/', function (response) {
console.log(response);
});
}
cinta();
$(document).ready(function () {
console.log('yesss');
});
This work for me in python flask在 python 烧瓶中为我工作
I had the same error with my piece of code,我的代码也有同样的错误,
$.getJson("/foo.json")
The issue was that my function is actually spelled问题是我的函数实际上是拼写的
$.getJSON
NOT $.getJson
.不是
$.getJson
。
Please use the full version of jquery CDN instead Slim/lite version.请使用完整版的 jquery CDN 而不是 Slim/lite 版。
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
without cross-origin and integrity, I hope it will work没有跨域和完整性,我希望它会起作用
