jquery file upload

Use below javascript function:


function uploadFile(fileObj) {
    var formData = new FormData();
    formData.append("file", fileObj.files[0]);
   
    var url = "sv/upload-file.php?action=upload-image";

    $.ajax({
        type : "POST",
        url : url,
        cache : false,
        contentType : false,
        processData : false,
        data : formData,
        success : function(json) {
            console.log(json);   
       },
        error : function (err){
            console.log(json);
        }
    });
}


And in Html code:

<input type="file" onchange="uploadFile(this)" />


Write your server side code in php, java or any other language.

If any doubt ask in comments.
