JavaScript/jQuery FileManager - Ajax
The Ajax file provider works with a virtual file system represented by an array of JSON objects loaded from a URL.
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
$(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"
});
});Options
