Get data from file input in JQuery
I created a form data object and appended the file:
var form = new FormData();
form.append("video", $("#fileInput")[0].files[0]);
and i got:
------WebKitFormBoundaryNczYRonipfsmaBOK
Content-Disposition: form-data; name="video"; filename="Wildlife.wmv"
Content-Type: video/x-ms-wmv
in the headers sent. I can confirm this works because my file was sent and stored in a folder on my server. If you don't know how to use the FormData object there is some documentation online, but not much. Form Data Object Explination by Mozilla
You can try the FileReader API. Do something like this:
<!DOCTYPE html>
<html>
<head>
<script>
function handleFileSelect()
{
if (!window.File || !window.FileReader || !window.FileList || !window.Blob) {
alert('The File APIs are not fully supported in this browser.');
return;
}
var input = document.getElementById('fileinput');
if (!input) {
alert("Um, couldn't find the fileinput element.");
}
else if (!input.files) {
alert("This browser doesn't seem to support the `files` property of file inputs.");
}
else if (!input.files[0]) {
alert("Please select a file before clicking 'Load'");
}
else {
var file = input.files[0];
var fr = new FileReader();
fr.onload = receivedText;
//fr.readAsText(file);
//fr.readAsBinaryString(file); //as bit work with base64 for example upload to server
fr.readAsDataURL(file);
}
}
function receivedText() {
document.getElementById('editor').appendChild(document.createTextNode(fr.result));
}
</script>
</head>
<body>
<input type="file" id="fileinput"/>
<input type='button' id='btnLoad' value='Load' onclick='handleFileSelect();' />
<div id="editor"></div>
</body>
</html>input file element:
<input type="file" id="fileinput" />
get file :
var myFile = $('#fileinput').prop('files');
