Note that «document.write» or equivalent statements in intrinsic event
handlers create and write to a new document rather than modifying the current
one. When a user
attempts to leave the field, the onblur event calls a JavaScript
function to confirm that userName has an acceptable value. A web page with no dynamically updating content is referred to as static — it just shows the same content all the time.
The controller needs to be stored in a file called acme-documents.get.js to match up with the descriptor. Normally, these should be nouns that make sense
from the perspective of the API consumer. When looking at a content model it probably makes sense to use the types as resources, so for the ACME content model we
could have the ACME Document, ACME Contract, and so on as resources.
Repository web scripts
It might also update the repository for URIs that intend to modify the repository (PUT, POST, and DELETE method bindings). The JavaScript has access to the URI query string, services, and repository data entry points. You can place controls on your content to
manage it and provide uniform access for a wide variety of client applications and services, such as a browser, portal,
search engine, or custom application. Here we first check if we got a search keyword passed in, if we don’t we will exclude the FTS from the query.
However,
it might not be the most realistic Web Script implementation, it is not something we would need to do in a “real” project. It is more likely that we will have to implement a ReST API based on a custom content model, such as the
ACME sample content model. When specified as in the above example it is assumed that the descriptor
file is located in the alfresco/extension/templates/webscripts/alfresco/tutorials directory.
Dynamic versus static code
If the user agent
doesn’t support scripts, the user may still retrieve the data through a
link. To quickly provision your site for many different countries and languages, you can provide a message bundle for the
Alfresco Share configuration. To do so, you need to wire in your own message bundle to Share that overrides uses of a script Share’s
default message bundle values. For human-readable web script responses it is often necessary to render the output in the preferred language of the user
or the preferred language of the client. This means that human-readable text cannot be placed directly in the web script
response template.
- The code is received in its programmer-friendly text form and processed directly from that.
- Repository web scripts encapsulate access and modification of content/data held in the content repository; therefore,
they are provided and exposed only by the Content Services server. - You can create amazing webpages without JavaScript, but JavaScript opens up a whole new level of possibilities.
Usually, the third party is someone you hired or a software that you bought. Website scripts are lines of code embedded in your website to make it more interactive, informative, and helpful—for you and your customers. They are also a leading cause of performance issues, as well as security and privacy risks. And, unless you know how to read code or manage Google Tag Manager containers, you can’t readily find or see all of the scripts that may be on your website. Control elements such as INPUT, SELECT, BUTTON,
TEXTAREA, and LABEL all respond to certain intrinsic events.

You can further boost the number of SoundCloud plays you receive in real-time by investing in SocialsUp service to monetize your files organically. You can choose from an array of customized real-time packages from such trusted service providers to promote your account. This is where the behavior of a custom Java-backed web script is encapsulated, including the population of the web
script model, which is returned from this method. The first method, getDescription(), returns a WebScriptDescription object, which is a Java representation of the
web script description XML document. The second method, execute(), is invoked by the Web Script Framework to initiate
the web script. Unlike scripted web scripts, Java-backed web scripts require more tooling for their development as you must compile
the Java source code, package, and deploy to the Content Services server.
When
these elements do not appear within a form, they may be used to augment the
graphical user interface of the document. Each scripting language has its own conventions for referring to HTML
objects from within a script. This specification does not define a standard
mechanism for referring to HTML objects. A Kawa web page script is a Kawa program that is invoked
by a web server because the server received an HTTP request.
Authenticating web scripts
Instead, Content Services relies on one of the many HTTP caches already available,
such as Squid (-cache.org), an HTTP caching proxy. Therefore, you must either embed an HTTP cache in your client
or deploy an HTTP-cache proxy in front of the Content Services server to enable caching. A key aspect of HTTP is its ability to support caching of HTTP responses, relieving workload on the HTTP server, which
does not have to re-create the HTTP response for every request.
Either form of scripting (i.e., CGI or direct execution) can be used to build up complex multi-page sites, but direct execution usually results in less overhead because of the lower number of calls to external interpreters. The controller can fetch content from different sources, such as the repository, or a remote Web Service on the Internet. Note that the special root object called remote, which is available for
Surf web scripts to fetch remote data on the internet, is not available when implementing a Repository Web Script
JavaScript controller. To fetch remote data on the Internet from a Repository Web Script, a Java controller is needed. Web scripts that provide JSON responses are often invoked directly from within a web browser by using the XMLHttpRequest
object.
Users of a web script only interact through the web script interface, which comprises its URI, HTTP method, and
request/response document types. All of these are described in the web script description document, which is defined
by the web script creator. Repository web scripts encapsulate access and modification of content/data held in the content repository; therefore,
they are provided and exposed only by the Content Services server.
By contrast, with static site generation, the application generates all the static HTML pages at build time. These pre-built pages are then sent to the client at each request, without having to build them again. This leads to faster rendering times, since a new page doesn’t have to be generated on every request; the server simply hands over a file it already generated in the past. The downside is that when some data on the page changes, it needs to be rebuilt. Sites generated by static site generation tools are often hosted on Netlify or GitHub pages. The Hello World Web Script demonstrates most of the features available to us when implementing web scripts.
It is the third layer of the layer cake of standard web technologies, two of which (HTML and CSS) we have covered in much more detail in other parts of the Learning Area. However, if we were to try and invoke the Web Script we would see an
exception as currently it is not set up to authenticate with a username and password. We cannot use the people root object
to access Repository information about users without being authenticated.
