When using hot controls it is expected to include data-control="mycontrol" to an element to bind it. Here are some helpful tips for working with this approach.
Binding multiple controls
Did you know you can bind multiple controls to the same element? It works just like a CSS selector! In this example the control1, control2 and control3 controls are all bound to the same DIV element.
<div data-control="control1 control2 control3"></div>
Using a custom selector
Sometimes, you cannot access the element to attach the data-control attribute. In these cases, you can listen to the render event and connect it using JavaScript instead. Here’s a sample code snippet for this:
// This adds data-control="full-calendar" to all elements with .some-class
var mySelector = '.some-class';
var myControl = 'full-calendar';
addEventListener('render', function () {
document.querySelectorAll(mySelector+':not([data-control~="'+myControl+'"]').forEach((element) => {
if (element.dataset.control) {
element.dataset.control = element.dataset.control + ' ' + myControl;
}
else {
element.dataset.control = myControl;
}
});
});
Here, we use the data-control~="..." selector to prevent it from adding twice; the ~ modifier checks if the name is found in a space (" ") separated list, just like CSS. Then, we append to that list or start a new list. Hot controls work like magic, so this logic can come any time – before or after the control is registered.
I hope this is helpful to someone out there!
