Once the page appears, fill in the requested fields with the correct values and click Go. As described in the previous task, the list of nodes in the folder will be visible. Now that the folder is shown in the panel, let's see how to upload new content. Clicking on the Show Upload Panel button, the uploading form will be shown, as presented in the following screenshot.
To upload the content, fill in the file name (extension included) and choose the file from the file system. Click the Upload button and your file will be uploaded into Alfresco repository in the current folder. The client will show you an updated list of nodes. Below is an example uploading a text file called My new content.txt.
Description of the solution for uploading content
Looking at the source code, the upload is possibile using the AJAX call on the /alfresco/api/-default-/public/alfresco/versions/1/nodes/<nodeId>/children service with method POST. Once the REST service is executed with success, the refresh of the list of nodes is requested, invoking the click event directly using the Go button.
