A JavaScript JSON request that includes several specific parameters

Here's a simple question:

JavaScript needs to make a request to the server using this URL:

myserver/scipt.php?LANG=EN&AGENT={"Login":{"name":"user","pass":"user"}}

How should I structure the URL and data for an Ajax call?

Is this approach correct?

var formData = {
            "login":$("#field1").val(),
            "pass":$("#field2").val()
               };

$.ajax({
    url:'http://myserver/scipt.php?LANG=EN&',
    type:'GET',
    data:'AGENT=' + $.toJSON(formData),
    success: function(res) {
                        alert(res);
                           }
      });

Appreciate your help!

Answer №1

If you're looking for optimal performance, consider using JSON with a POST request instead of GET. GET comes with certain limitations that may hinder your progress.

Other than that, it appears that your code is in good shape.

UPDATE:

I apologize, but upon further inspection, your code needs some adjustments.

Please modify the data line to read as follows:

data: $.toJSON(formData),

Answer №2

In order to transmit the information to the server, it should be formatted as a map.

The information is already structured in json format, so there is no need to convert it using $.toJSON again.

Instead of sending it like this:

data:'AGENT=' + $.toJSON(formData),

You should send it in this manner:

 data:{ 'AGENT' : {'Login' : formData } },

Answer №3

Make sure to properly encode any strings that are being passed through Ajax requests.

Similar to submitting a form, it's important to assign all query string data to the data attribute in order to prevent overwriting any existing query strings.

url:'http://myserver/scipt.php',
type:'GET',
data: { 
    "AGENT": $.toJSON(formData),
    "LANG": "EN"
},

Remember, if you are sending sensitive information like user credentials, opt for using POST requests instead of GET to avoid caching and storing these details in server access logs.
