jQuery Bindings

The kvision-jquery module allows you to work with jQuery library, with the help of a wrapper library jquery-kotlin.

jQuery object

You can use the io.kvision.jquery.jQuery object to create a jQuery instance with all supported selector types. You can use them to directly access and modify underlying DOM elements and their attributes.
import io.kvision.jquery.invoke
import io.kvision.jquery.jQuery

getElementJQuery() method

The extension function getElementJQuery() can be used to access the jQuery instance bound to the underlying DOM element of the component. It gives you the possibility to easily access and modify the default behavior of KVision components.
This method should only be called after the component has been rendered. It returns null otherwise. It's a good practice to overwrite afterInsert method from the Widget class in your own classes, and call getElementJQuery() from there. Alternatively you can use addAfterInsertHook method of the Widget class to wait until rendering is complete without the need to create your own class.
override fun afterInsert(node: VNode) {
this.getElementJQuery()?.parent("#id")?.click { e ->
console.log("clicked parent: ${e.clientX}, ${e.clientY}")
There is also a getElementJQueryD() method which returns a value of dynamic type. It can be used to initialize and run code from external NodeJS modules and events to create custom KVision components.
override fun afterInsert(node: VNode) {
