"Exploring the versatility of Typescript coupled with the power

I've come across the code snippet below:

Updated: added return to $.ajax

searchAjax({url = 'app/php/check.php', data}: {url: any, data: any}): any 
{   
    return $.ajax({
        url: url,
        type: 'post',
        dataType: 'text', 
        data: { data },
        success: function (return_data)
        {   
            return String(return_data);
        },  
        error: function (xhr, status, error) 
        {   
            var err = eval("(" + xhr.responseText + ")");
            console.log(err.Message);
            return err.Message;
        }   
    }); 
}

Currently, check.php is set to return echo 'hi'. In order to test it, I'm attempting to log the response (in this case return_data). However, when trying to console.log it, an error message of EXCEPTION: hi is not defined pops up.

Update: Now I receive an object with various details and a responseText containing the actual response.

Answer №1

It appears that your eval function is not recognizing the correct text input. It seems like the apostrophe in your result: "echo 'hi'" is being removed, causing it to actually evaluate as "echo hi". This issue could be related to a problem with the ajax client or possibly caused by your API stripping the apostrophes. I recommend checking what data your browser is receiving from the API to pinpoint the source of the problem.

In addition, please note that the use of "echo" is not native to JavaScript.

Answer №2

It seems like you may have missed the mark with your timing in responding. Instead of displaying the response, it appears that you are attempting to interpret the response as a piece of javascript code. When running this evaluation, javascript does not recognize 'echo hi' as a valid string, leading to the error message 'hi is not defined'. Furthermore, you are not actually showcasing the ajax response itself, but rather the result of the evaluation process, which clearly results in failure. To properly display the response, you should use: console.log(xhr.response);
