Attempting to send a String in a particular structure

Question

Attempting to send a String in a particular structure

I'm facing an issue with the format I'm trying to pass. The expected format should be like this:

[{"blah.png"},{"blah2.png"}]

However, instead of getting the desired format, I am receiving this:

["blah.png","blah2.png"]

Below is the code snippet that I am using:

var filesObj = [];

$('#fileList .files .fileName').each(function () {
    var name = $(this).text();
    filesObj.push(name);
});

console.log(filesObj);
$.ajax({
    type: "POST",
    url: "/dat/Controller",
    data: JSON.stringify(filesObj),
    dataType: "json"
});

If anyone can offer assistance in resolving this issue, it would be greatly appreciated. Thank you!

[{"image1.png"},{"image2.png"}]

Not meeting the requirements for valid JavaScript or JSON. If you prefer using objects instead of strings, your code should be structured like this

$('#fileList .files .fileName').each(function () {
    var name = $(this).text();
    filesObj.push({"name": name});
});

In this case, each object contains a key "name", with the corresponding value coming from $(this).text();

Here is a way to achieve this:

let filesArray = {files:[]}; //initialize as an array in JavaScript

$('#fileList .files .fileName').each(function () {
    let name = $(this).text();
    filesArray.files.push(name);
});

console.log(filesArray);
$.ajax({
    type: "POST",
    url: "/FileUpload/ImportCommit",
    data: JSON.stringify(filesArray),
    dataType: "json"
});

If you're curious about what lies ahead...

The solution to my issue didn't involve changing the format of the string, but rather adjusting the AJAX call.

I structured my object like this:

var filesObj = [];

$('#fileList .files .fileName').each(function () {
    var name = $(this).text();
    filesObj.push(name);
});

This sends a string like:

["delete-icon.png","something.exe"]

The key was to modify my AJAX request to use POST in this way:

$.ajax({
    type: "POST",
    url: "/dat/Controller",
    data: JSON.stringify(filesObj),
    contentType: "application/json",
    traditional: true,
    success: function (result) {
        console.log("Success: " + result);
    },
    error: function (result) {
        console.log("Error: " + result);
    }
});

Switching from using dataType to contentType and including traditional: true resolved the issue for me. I believe this is because the data being sent wasn't truly in JSON format. Adding traditional: true was more of a precautionary measure.
