这是实验性技术
检查浏览器兼容性表格要小心谨慎在生产中使用这之前。

非标
此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

只读 webkitEntries 特性为 HTMLInputElement interface contains an array of file system entries (as objects based on FileSystemEntry ) representing files and/or directories selected by the user using an <input> element of type file , but only if that selection was made using drag-and-drop: selecting a file in the dialog will leave the property empty (bug 1326031).

The array can only contain directories if the webkitdirectory 特性为 true . This means the <input> element was configured to let the user choose directories.

This property is called webkitEntries in the specification due to its origins as a Google Chrome-specific API. It's likely to be renamed someday.

句法

var entries = HTMLInputElement.webkitEntries;

值

An array of objects based on FileSystemEntry , each representing one file which is selected in the <input> element. More specifically, files are represented by FileSystemFileEntry objects, and, if they're allowed, directories are represented by FileSystemDirectoryEntry 对象。

范例

This example shows how to create a file selection <input> element and process the selected files.

HTML

<input id="files" type="file" multiple>

JavaScript

document.getElementById("files").addEventListener("change", function(event) {
  event.target.webkitEntries.forEach(function(entry) {
    /* do stuff with the entry */
  });
});

Each time a change event occurs, this code iterates over the selected files, obtaining their FileSystemEntry -based objects and acting on them.
