Valider l'extension et la taille du fichier avant de soumettre le formulaire

J'utilise le plug-in de validation jQuery et souhaite valider l'extension et la taille du fichier avant de soumettre un formulaire.

"use strict";
$('#update_profile').validate({
    rules: {
        FirstName: {
            required: true,
            maxlength: 20
        },
        image: {
            required: true,
            extension: "jep | jpeg",
            filesize : 50000,
        }
    }
});

Je veux un code similaire à celui ci-dessus.

Vous devez écrire une règle personnalisée pour valider la taille du fichier. Les extensions de fichier doivent également être transmises sous forme de chaîne séparée par des virgules.

$.validator.addMethod('filesize', function (value, element, param) {
    return this.optional(element) || (element.files[0].size <= param)
}, 'File size must be less than {0}');

jQuery(function ($) {
    "use strict";
    $('#update_profile').validate({
        rules: {
            FirstName: {
                required: true,
                maxlength: 20
            },
            image: {
                required: true,
                extension: "jpg,jpeg",
                filesize: 5,
            }
        },
    });
});

  <input type="submit" value="Save" />
</form>

$.validator.addMethod('filesize', function (value, element, arg) {
            var minsize=1000; // min 1kb
            if((value>minsize)&&(value<=arg)){
                return true;
            }else{
                return false;
            }
        });

        $("#myform" ).validate({
            rules: {
                file_upload:{
                    required:true,
                    accept:"application/pdf,image/jpeg,image/png",
                    filesize: 200000   //max size 200 kb
                }
            },messages: {
                file_upload:{
                    filesize:" file size must be less than 200 KB.",
                    accept:"Please upload .jpg or .png or .pdf file of notice.",
                    required:"Please upload file."
                }
            },
            submitHandler: function(form) {
                form.submit();
            }
        });
