Hi, mastering JavaScript is critical if you want to be a modern, professional developer: www.udemy.com/course/professional-javascript-course/?referralCode=0C1D5752923168BC87C2 Also, if you are a front-end developer then mastering CSS (including Flexbox, CSS Grid, etc.) is equally important: www.udemy.com/course/professional-css/?referralCode=4C3C08E82629E6B15752

Hi, Thank you so much for the amazing tutorial. I have 1 issue, I did the exact same thing, but I get the "crbug/1173575, non-JS module files deprecated." then the page is not working. What could be the issue here?

@troymelok831 Год назад

Hi, thanks for sharing. I don´t understand why is needed to convert to json if we can send FormData directly and then in the php file get data with POST if we use this method to send of course

@marynakryvoruchenko1393 Год назад

Thanks for the video! Is there a json file that the information gets stored to so I could display it in another file?

When I try to console log my elements, it says « null » and when I try to send them to the api it says « failed to load resource: server responded with 401 ». Do you have ideas on how I could fix it ? Thank you for your video

Hi, probably you didn’t select the HTML-element properly with querySelector

What if the data to submit is an array of json's? when i send to the backend it gets there on a whole differente format and messes up everything, thank you!

@ByteGrad Год назад

Hi, I don’t know what an array of json’s. You have a code example?

@valdompinga3790 Год назад

@@ByteGrad Hello thanks for answering, my issue is that im trying to post data to a server that expects a JSON array, an exemple of it is: [{name : "Joe"},{name : "Bill"} ], i tested the endpoint using Insomnia REST, posting an hardcoded JSON array and it works fine, but on the frontend code, the js object is stored in variable because i had to do data pre propressing, so when i posted the data, i did: JSON.stringify(varWithPreprocessedJsObject). What the server recieved it would be equivalent to {[{"name" : "Joe"},{"name" : "Bill"} ]" : ''} So my question is, do identify something i did wrong? Sorry for the long text... thank you!

@ByteGrad Год назад

When you do JSON.stringify() you make it JSON format. Maybe it was already JSON format when you do JSON.stringify()? You would be doubling it

Hi, are you on UpWork by any chance? as i am trying to fix a piece of code, that needs a "save post" button on the front end, to save response text into a post, it supposed to be straight forward, but I am having trouble with the authenticity token I think, which wont allow the submission to go through. Is there any way to get your help? do you do that kind of thing? thank you
