jQuery AJAX函数未定义

标签: javascript jquery ajax

我正在尝试从jQuery发起$.get()调用,但是我得到的只是以下错误;

Uncaught TypeError: $.get is not a function
    at HTMLDocument.<anonymous> (client.js:12)
    at l (jquery.min.js:2)
    at c (jquery.min.js:2)

我已经搜索了所有内容,但似乎找不到答案。我正在使用Google CDN导入jQuery。 (https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js

最小示例

$(document).ready(function() {
	jQuery.get('echo/authstatus', function(data) {
		console.log(data);
	});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

完整代码段

let denied = `<div class="alert alert-danger" role="alert">
  <strong>Access Denied!</strong> Please check your username and password, then try again.
</div>`;
let granted = `<div class="alert alert-success" role="alert">
  <strong>Access Granted!</strong> Welcome, please wait while we redirect you.
</div>`;
let disabled = `<div class="alert alert-warning" role="alert">
  <strong>Authentication disabled!</strong> Sorry, we have temporarily disabled authentication!
</div>`;

$(document).ready(function() {
	jQuery.get('echo/authstatus', function(data) {
		console.log(data);
	});
});

您应该删除底部的第一个脚本标签 Dim arr1 As New List(Of String) arr1.AddRange(IO.File.ReadAllLines("text file 1")) Dim arr2 As New List(Of String) arr2.AddRange(IO.File.ReadAllLines("text file 2")) Dim searchstring As String = "test1" 'You can replace test1 with the string you are searching the text file for Dim index1 As Integer = 0 Dim index2 As Integer = 0 'Getting the index of the string in the list '******************************************* For x As Integer = 0 To arr1.Items.Count - 1 If arr1(x).StartsWith(searchstring) Then index1 = x End If Next For x As Integer = 0 To arr2.Items.Count - 1 If arr2(x).StartsWith(searchstring) Then index2 = x End If Next '******************************************* Dim split1() As String = Split(arr1(index1), ",") Dim split2() As String = Split(arr2(index2), ",") Dim sum As Integer = Integer.Parse(Trim(split1(1))) + Integer.Parse(Trim(split2(1))) 'Writing the sum to another test file, the "output.txt" file would be created on your desktop, you can replace the path's string with your custom location Dim path As String = Path.Combine(My.Computer.FileSystem.SpecialDirectories.Desktop, "output.txt") Dim finaltext As String = searchstring + "," + sum.ToString System.IO.File.AppendAllLines(path, finaltext)
