The presence of decimal values within an AJAX URL

Struggling to pass decimal values in an AJAX request to a server-side endpoint. Everything runs smoothly except when trying to include a decimal value in the URL. The "." character is recognized as reserved within the URL schema, causing a 404 error. Seeking advice on how to successfully transmit decimal values through an AJAX request.

The current endpoint structure appears as follows: /domain/some-url/?value1=5&value2=2.3 However, using the above URL results in a 404 error. Conversely, changing "value2" to either a whole number or a string yields expected responses. For instance, /domain/some-url/?value1=5&value2=2 provides a successful response.

Might there be a standardized method to address this issue?

Answer №1

The use of . as a reserved character in URLs is a common misconception. According to the specifications outlined in https://www.rfc-editor.org/rfc/rfc3986#section-2.3, it is not considered a reserved character, so whether it is URL-encoded or not should have no impact.

It appears that the issue may lie with the server-side script failing to recognize dots in the argument provided. Without further information, it is challenging to pinpoint the exact reason for this discrepancy.

Answer №2

It appears that the issue lies within your server, as . is not a reserved character. I conducted an experiment using encodeURI in my web browser:

> encodeURI("/domain/some-url/?value1=5&value2=2.3")
"/domain/some-url/?value1=5&value2=2.3"

The outcome remained unchanged. I recommend giving it a try yourself.

Answer №3

The dot itself is not the issue here. Why would a simple dot be considered as a reserved character in a URL? If that were the case, we wouldn't be able to use something like /img/someimg.jpg. It seems more likely that the problem lies with how your server interprets and processes the request.

To confirm this, I conducted a test using one of my own server-side scripts located at 

http://testbed.nicon.nl/v8test/json.xjs?testone=0.234&test2=4.56
. The script was accessed successfully and functioned as expected, without any issues regarding decimals.

Answer №4

To enable the use of decimals in parameters, ensure that your .htaccess file or routing script on your domain/server allows for it.

If not, you can pass decimal values in the URL as shown below:

/domain/some-url/?value1=5&value2=2.3

This method is a valid way to include decimal values in the URL.

Answer №5

For your ajax request, ensure to include the parameters as shown below:

data: { num1:5, num2: 2.3 }
