我正在使用 html5 和 xhr 进行多文件上传,如您所见,我正在循环发送请求,这是一个不好的概念,但是当我将文件发送到循环外并且只有最后一个文件得到时,我无法上传文件上传。我哪里错了?
$('#uploadimg').on('click', function(e) {
var files = document.getElementById('files').files;
var formData = new FormData();
for (var i = 0; i < files.length; i++) {
formData.append('file', files[i]);
var xhr = new XMLHttpRequest();
xhr.open('POST', 'http://localhost/ajaxuploader/upload/uploadimg');
xhr.onload = function() {
if (xhr.status === 200) {
console.log('all done: ' + xhr.status);
} else {
console.log('Something went terribly wrong...');
}
};
xhr.send(formData);
}
// now post a new XHR request
});
代码点火器
public function uploadimg (){
$config['upload_path'] = FCPATH . 'uploads/' ;
$config['allowed_types'] = 'gif|jpg|png|jpeg|pdf|doc';
$config['remove_spaces'] = 'TRUE';
$this -> load -> library('upload', $config);
//$this->upload->initialize($config);
foreach ($_FILES as $k => $f) :
$this -> upload -> do_upload($k);
endforeach;
//$this->index();
}
