Ajax

The Ajax file provider works with a virtual file system represented by an array of JSON objects loaded from a URL.

Export: default
Type:

Object

Assign the URL to the url option. Data object fields should have conventional names listed in the url description. Otherwise, specify [fieldName]Expr options: nameExpr, sizeExpr, dateModifiedExpr, and so on.

The following code shows how to bind the FileManager to the Ajax file provider:

jQuery
index.js
$(function() {
    $("fileManagerContainer").dxFileManager({
        fileProvider: new DevExpress.FileProviders.Ajax({
            url: "https://mydomain.com/data.json",
            thumbnailExpr: "icon",
            // ...
        })
        // A shortcut that can be used if object fields have conventional names
        fileProvider: "https://mydomain.com/data.json"
    });
});
