Ошибка ajax is not a function

The Ajax is not a function is an Ajax request error. It occurs due to various reasons, such as: Using the wrong Ajax version and syntax errors.

However, there are other reasons behind this error, and this article covers all of them, including its various solutions. Let’s begin.

Why Is the Ajax Is Not a Function Error Message Occurring?

The reason why the Ajax is not a function error message occurs is that the programmer is using the wrong version of Ajax. However, other reasons, such as syntax errors or compatibility issues, also play a role in the occurrence of this error.

Some other reasons are listed below.

• The version doesn’t support Ajax.
• Syntax error
• Use jqXHR as a function.
• Ajax functions are missing.

– The Version Doesn’t Support Ajax

The major reason why this error message occurs is that the version of the function files the programmer is using does not support Ajax. Many web pages send AJAX requests to a server.

Because the response relies on the cooperation of the server and the network between the client and the server, the user can expect AJAX errors, such as: Your JavaScript program receives an error response instead of data. This occurs because the program has to wait too long for the response.

Therefore, when the function and webpage are incompatible with each other, the response will occur, due to which the error message arises.

– Syntax Error

In such types of error messages, syntax errors are the biggest reason behind them. Programmers use wrong functions or operations, due to which errors occur. Some common Ajax error messages are listed below.

• “uncaught typeerror: $.ajax is not a function jquery slim.
• $.ajax is not a function laravel.
• $.ajax is not a function node js.
• $.ajax(…).done is not a function.
• $.ajax is not a function bootstrap 4.
• $.ajax is not a function chrome console “.

– Use JQXHR as a Function

When the programmer uses jQXHR as a function instead of an operation, the error occurs. Do remember that jQXHR is not a function.

When an operand is used as a function, the compiler cannot execute it properly and thus throw the programmer an error message in return. Let’s see the example below.

For example:

Explanation:

Upon the execution of the above program, the output will contain an error message. This is because the user has called $.ajax without arguments “$.ajax()” due to which the return value is a jQXHR object. JQXHR can never be an object. Thus, $.ajax() will throw an error message.

– Ajax Functions Are Missing

When the programmer is using the slim version of Ajax, which is set as default, the functions will be missing, and the program will not work smoothly.

Therefore, not only will the program won’t work, but it will also be full of structural errors, including various syntax errors. So, the programmer should confirm from their browser’s settings whether they’re using the slim version or not.

How To Resolve the “Ajax Is Not a Function” Error Message?

In order to resolve the Ajax is not a function error message, the programmer has to check and correct the program’s syntax errors and use the correct version of Ajax. However, other reasons include using the correct json file or trying to run the program on the browser.



– Correct the Syntax Error

The first thing to check in order to remove this error message is by checking the program’s syntaxes and identifying its errors. If they’re found, the programmer can use the manual method to correct them. Otherwise, there are special software just for this purpose, so they can use them.

In the below example, the programmer has made a syntax error by placing parentheses after the Ajax function and then adding another set of parentheses in order to define the argument list. See the example below/

Wrong example:

Correct example:

The programmer has to remove the parentheses around the ajax function. The program should look like this:

– Run the Program in a Browser

The programmer has to run the program in the browser after correcting the error in the node.js file. For programmers who try to run the program in nodejs, it will show an error. This is because jQuery needs a browser to work.

Some programmers might try to get the import to run the program and may be logging console.log($) with incompatible functions, and when trying to console.log($.ajax), it returns undefined; thus, causing an error.

Therefore, this means that the problem lies in “node ” and not in typescript. So, try to run the same program in the browser, and the error will be removed. Look at the example below.

For example:

– Use the Full Version Instead of the Slim Ajax Version

The programmer should use the full version of Ajax or jquery and not the slim version. This is because the full version contains all the functions and helps the program run smoothly. Moreover, using the full version of Ajax will remove the error message as well.

If the programmer is using the jquery cdn-script link that comes with jquery, it is by default set to slim.jquery.js, which doesn’t have the ajax function in it. The details of both versions are given below.

Slim version syntax:

– Add a Script Correctly

Ensure that any scripts the programmer includes redirect to the minified version rather than the slim one. By doing so, the error will be eliminated. Having numerous instances of the jQuery library loaded on the same page may also result in the issue. Here is an example of the ajax function in operation.

For example:

Code for the index.js file:

FAQs

1. What Is the Difference Between Jquery Ajax and Ajax?

The difference between jquery ajax and Ajax is that jQuery is a JavaScript library for designing and making web development tasks easy for programmers. It lets the programmers run javascript outside of the browser. Whereas, AJAX is a web development method for making asynchronous calls to the server.

2. What Is AjaxCDN?

AJAX CDN is the Content Delivery Network (CDN) that hosts popular third-party JavaScript libraries, i.e., jQuery. It also enables the user to easily add them to their web applications. The user can use jQuery by adding a <script> tag to their page that points to ajax.aspnetcdn.com.

Conclusion

After reading this guide, the reader can understand the logic behind this error and how they can resolve it using different methods. A few points to notice are:

• Never use the slim version of ajax, as it does not contain all the functions.
• The programmer should be careful while typing functions because they can use the function as an operand and vice versa.
• Run the JQuery program on the browser instead of in nodejs to eliminate the error.

The reader can easily resolve similar ajax errors on their own by reading this guide. Thank you for reading!

AJAX( Asynchronous JavaScript And XML) is a set of web development techniques that uses many web technologies on the client-side to create asynchronous web applications. With Ajax, web applications can asynchronously send and retrieve data from a server without interfering with the existing page’s display or behavior.

AJAX is not a programming language. It requires a built-in browser with the XMLHttpRequest object that requests data from the server, and it uses JavaScript and HTML DOM to display data.

Problem

Let’a create a simple AJAX request that returns some data from a MySQL database:

function AJAXrequest(url, postedData, callback) {
    ＄.ajax() ({
        type: 'POST',
        url: url,
        data: postedData,
        dataType: 'json',
        success: callback
    });
}

You call the AJAX request,

AJAXrequest('newajax.php', Data, function(data) {
});

but you get the following error on your console:

TypeError: ＄.ajax(...) is not a function.

Solution

The solution is pretty simple. Many programmers make the mistake of using the jquery cdn-script link that comes with jquery. By default, this is a slim version of jquery, (slim.jquery.js), not the full jquery version. This slim version lacks some key modules, especially the ajax function. Therefore, the slim version does not recognize the ajax function.

To use the ajax function, use:

<script src="https://code.jquery.com/jquery-3.1.1.min.js">

Do NOT use:

<script src="https://code.jquery.com/jquery-3.1.1.slim.min.js"
