# Accessing the SWISH interface The jquery/3 predicate can be used to access arbitrary JavaScript functionality on the SWISH interface from Prolog. This notebook gives some examples for using this functionality. ## Status This API is *speculative*. Please consider the possibilities and make suggestions how to turn this into something generally useful for customizing SWISH and/or define new types of applications using it. ## Get access to the tabs The jQuery interface was added to provide access to the tabs in the SWISH interface. Our first example asks for for the available tabs. It returns an list holding a _dict_ for each tab.

The =|swish#tabData|= jQuery plugin method accepts an `options` dict with the following values: - active:Boolean Restrict the result to the active tab - type:String Restrict the result to tabs with objects of this type - data:Boolean|String If `true`, include the content of the reported tabs. If `"if_modified"`, only include the data if the tab was modified. The example below fetches the data from the active tab.

## The potential Except for querying UI properties, the general jQuery API can be used to add new element to the interface. The `this` root selector refers to the jQuery plugin `prologRunner`, which runs a single query. The query below inserts some HTML into the runner DOM. This level of interaction with the interface is probably not desirable. Restricted to a documented set of jQuery selectors and methods however, it can be used to generalise the user interaction.
