如何将图像从本地存储到 vaadin-upload?我找不到来自 vaadin-upload 的输入。希望你能帮助我,谢谢!
Vaadin-upload 正在与 Polymer 3.0 一起工作。
<vaadin-upload id="upload" no-auto></vaadin-upload>
--------
ready(){
super.ready();
var upload = this.$.upload;
var files = upload.files;
var newImage = JSON.parse(localStorage.newAttachment);
var maxImage = newImage.length;
for(var i = 0; i < maxImage; i++) {
files.indexOf(localStorage.getItem(newImage[i].data));
}
}
它显示无。
