How to call a function from ruby-on-rails (HTML)?
Let I have a button
```html
<button type="button" onclick = "myfunction()" class="collapsible">Expand content</button>
```
And, I have a JS function.
```javascript
function collapse() {
var coll = document.getElementsByClassName("collapsible");
var i;
for (i = 0; i < coll.length; i++) {
coll[i].addEventListener("click", function() {
this.classList.toggle("active");
var content = this.nextElementSibling;
if (content.style.display === "block") {
content.style.display = "none";
} else {
content.style.display = "block";
}
});
}
}
```
Usually, we call a JS function in HTMl using `onclick`. What if it comes to Ruby-on-rails? I noticed that I can't call a function that way in Ruby-on-rails. How to call a function from ruby-on-rails (HTML)?
