Trying to access file attributes from an input field after a file is selected. Tried this but get the error 'file not defined'
var file = $("#uploadedfile").prop("files")[0];
var fileName = file.fileName;
var fileSize = file.fileSize;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");
If #uploadedfile is an input with type "file" :
var file = $("#uploadedfile")[0].files[0];
var fileName = file.name;
var fileSize = file.size;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");
Normally this would fire on the change event, like so:
$("#uploadedfile").on("change", function(){
var file = this.files[0],
fileName = file.name,
fileSize = file.size;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");
CustomFileHandlingFunction(file);
});
To get the filenames, use:
var files = document.getElementById('inputElementID').files;
Using jQuery (since you already are) you can adapt this to the following:
$('input[type="file"][multiple]').change(
function(e){
var files = this.files;
for (i=0;i<files.length;i++){
console.log(files[i].fileName + ' (' + files[i].fileSize + ').');
}
return false;
});
<form id = "uploadForm" name = "uploadForm" enctype="multipart/form-data">
<label for="uploadFile">Upload Your File</label>
<input type="file" name="uploadFile" id="uploadFile">
</form>
<script>
$('#uploadFile').change(function(){
var fileName = this.files[0].name;
var fileSize = this.files[0].size;
var fileType = this.files[0].type;
alert('FileName : ' + fileName + '\nFileSize : ' + fileSize + ' bytes');
});
</script>
Note: To get the uploading file name means then use jquery val() method.
For Ex:
var fileName = $('#uploadFile').val();
I checked this above code before post, it works perfectly.!
Just try
var file = $("#uploadedfile").prop("files")[0];
var fileName = file.name;
var fileSize = file.size;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");
It worked for me
The input.files attribute is an HTML5 feature. That's why some browsers din't return anything.
Simply add a fallback to the plain old input.value (string) if files doesn't exist.
