我在代码中使用{{uploader}},每当用户上传图片时,都会显示他("上传+ fileName ...")
这是它的代码
let upload = ( options ) => {
template = options.template;
let file = _getFileFromInput( options.event );
let config = options.config;
_setPlaceholderText( `Uploading ${file.name}...` );
_uploadFileToAmazon( file, config );
};
问题是当用户选择一个大尺寸文件时他会等待很长时间,所以最好有一个上传百分比而不是("加载...")
我正在使用meteor add edgee:slingshot包上传到Amazon S3
这是调用上传者的代码
var uploader
if (config === '1') {
uploader = new Slingshot.Upload( "uploadToAmazonS3Cg1" );
}
if (config === '2') {
uploader = new Slingshot.Upload( "uploadToAmazonS3Cg2" );
}
if (config === '3') {
uploader = new Slingshot.Upload( "uploadToAmazonS3Cg3" );
}
var progress = Math.round(uploader.progress() * 100);
我尝试创建模板助手,如下所示:
Template.uploader.helpers({
progress: function(uploader){
var progress = Math.round(uploader.progress() * 100)
return progress;
}
});
然后我用{{progress}}
在我的助手里面调用它,它没有工作
我怎么能做到这一点?
答案 0 :(得分:0)
我使用这样的东西:
var uploader = new Slingshot.Upload("myFileUploads")
// ...get your upload started and save the uploader (in state for React or in a template variable in Blaze)
var progress = Math.round(uploader.progress() * 100)
