trigger element|selector
trigger 唤出文件选择器,可以是:

Methods
链式调用:
var uploader = new Uploader({
trigger: '#upload-icon',
name: 'image',
action: '/upload',
data: {'xsrf': 'hash'}
}).success(function(response) {
alert(response);
}).error(function(file) {
alert(file);
});
Data API
<a id="upload" data-name="image" data-action="/upload" data-data="a=a&b=b">Upload</a>
<script>
var uploader = new Uploader({'trigger': '#upload'});
// more friendly way
// var uploader = new Uploader('#upload');
uploader.success(function(response) {
alert(response);
});
</script>
Advanced
Demo in API section could not be controlled. When you select a file, it will
be submitted immediately. We can broke the chain with change
:
var uploader = new Uploader({
trigger: '#upload-icon',
name: 'image',
action: '/upload',
data: {'xsrf': 'hash'}
}).change(function(files) {
for (var i=0; i<files.length; i++) {
console.log('you are selecting ' + files[i].name + ' Size: ' + files[i].size);
}
// Default behavior of change is
// this.submit();
}).success(function(response) {
alert(response);
});
Now you should handle it yourself:
$('#submit').click(function() {
uploader.submit();
});
Show Progress
It is impossible to show progress, but you can make a fake prgress.
var uploader = new Uploader({
trigger: '#upload-icon',
name: 'image',
action: '/upload',
data: {'xsrf': 'hash'},
progress: function(e, position, total, percent, files) {
$('#progress').text('Uploading ... ' + percent + '%');
}
}).change(function(files) {
// before submit
$('#progress').text('Uploading ...');
this.submit();
}).success(function(response) {
$('#progress').text('Success');
alert(response);
});
Seajs Hint
Load uploader with seajs:
seajs.use('upload', function(Uploader) {
var uploader = new Uploader({
});
});
