TypeScript does not recognize the $.ajax function

Question

TypeScript does not recognize the $.ajax function

Looking for help with this code snippet:

    $.ajax({
        url: modal.href,
        dataType: 'json',
        type: 'POST',
        data: modal.$form.serializeArray()
    })
        .done(onSubmitDone)
        .fail(onSubmitFail);

Encountering an issue where TypeScript is flagging a message at the $.ajax call, saying:

Supplied parameters do not match any signature of call target.

I've double-checked my $.ajax setup and made sure to reference the jQuery definitions correctly. Any suggestions on what might be causing this error?

Answer №1

When referencing jquery.d.ts:

ajax(url: string, options: JQueryAjaxSettings);

This is the defined signature for the ajax function. To ensure compatibility with TypeScript, it is recommended to extract the url from the settings object and pass it as a separate parameter. Alternatively, you can modify the definitions in jquery.d.ts to allow for passing settings only during function invocation.

Although the original jQuery definitions did not initially include the overload without the Url, they have since been revised and you can access the most recent version from GitHub:

Additionally, you can find an updated mirror of the jQuery definitions at https://github.com/borisyankov/TypeDefinitions
