Question

我使用Yii2框架。我想显示文件上传进度。我不需要带有拖放或预览功能的复杂界面。只有进度条和可能的“取消”按钮。您能指出一个简单的例子吗？谢谢。

最终我用jQuery ajax做到了。

js：

function upload() {
var input = $('#archiveInput');
var files = input.prop('files');
if (files.length > 0) {
    var data = new FormData();
    data.append('archive', files[0]);
    $.ajax({
        url: input.data('upload-url'),
        type: 'POST',
        data: data,
        cache: false,
        contentType: false,
        processData: false,
        success: function () {
            alert('Upload Complete');
        },
        xhr: function() {
            var myXhr = $.ajaxSettings.xhr();
            if (myXhr.upload) {
                myXhr.upload.addEventListener('progress', onProgress);
                return myXhr;
            }
        }            
    });
}
}

function onProgress(ev) {
if (ev.lengthComputable) {
    var progress = parseInt(ev.loaded / ev.total * 100, 10); 
    $("#progress .progress-bar").css(
        "width",
        progress + "%"
    );
}
}

php控制器：

public function actionUpload($idSupply)
    {
        $directory = FileHelper::normalizePath(Yii::getAlias('@app') . '/uploads/' . $idSupply);
        if (!is_dir($directory)) {
            FileHelper::createDirectory($directory);
        }
        $fileName = 'archive.zip';
        $filePath = $directory . DIRECTORY_SEPARATOR . $fileName;
        if (is_file($filePath)) {
            unlink($filePath);
        }
        move_uploaded_file($_FILES['archive']['tmp_name'], $filePath);

    }
