Leveraging $.ajax for fetching HTML and converting it into a JavaScript array

let urlPath = window.location.pathname.split("/"),
    idFromUrl = urlPath[2],
    dataEndpoint = "/bulletins/" + idFromUrl + "/data";

$.ajax({
    url: dataEndpoint,
    type: "get",
    dataType: "html",
    success: function (data) {
        let dataArray = data.replace(/"/g, '"');

        console.log(dataArray);
    }
});

I need to extract the content from an HTML page. The content is very basic - just a simple "array" in plain text format, causing JavaScript to treat it as a string instead of an array when retrieved. This is the content of that HTML page:

[{"sermontitle":"test","welcome":"test","_id":"52e7f0a15f85b214f1000001"}]

If I don't replace the "'s, the console.log output will be 

[{"sermontitle":"test","welcome":"test","_id":"52e7f0a15f85b214f1000001"}]

My question now is how can I convert this HTML string (already in "array" form) into an actual array?

Answer №1

To convert JSON data into a JavaScript object, you can utilize the JSON.parse method.

JSON.parse(dataObj);

Answer №2

To convert the retrieved HTML snippet into JSON format, you can use:

JSON.parse(dataObj);

Answer №3

Modify the "dataType" parameter to "json" to automatically convert the data:

var urlArray = window.location.pathname.split("/"),
    idFromUrl = urlArray[2],
    dataPath = "/bulletins/" + idFromUrl + "/data";

$.ajax({
    url: dataPath,
    type: "get",
    dataType: "json",
    success: function (data) {
        console.log(data);
    }
});

If you are getting " instead of ", ensure that the AJAX response is properly formatted as JSON.
