Ajax function try catch block not correct-CodePudding

I have the code below but I'm not sure if my try-catch block is actually right. Can someone guide me please?

var upload = new FormData($("#video_upload")[0]);
 

    try {
            $.ajax({
                url: "files/video_upload",
                enctype: 'multipart/form-data',
                type: 'POST',
                data: upload,
                async: false,
                success: function (data) {
                    $('.filesToUpload').empty();
                },
                cache: false,
                contentType: false,
                processData: false
            });
    } catch (Exception e) {
    alert (‘Upload Failed.');
    }

CodePudding user response：

Instead of using try-catch around ajax. You can use the error function return by ajax request when the request fails.

 $.ajax({
                url: "files/video_upload",
                enctype: 'multipart/form-data',
                type: 'POST',
                data: upload,
                async: false,
                success: function (data) {
                    $('.filesToUpload').empty();
                },
                //Add this
                error: function (error) {
                    console.log(error)
                },
                cache: false,
                contentType: false,
                processData: false
            });
