Slugify a string from the object data input (no classes just js)

@swina

//create a button (layout component) in the object class

//example you want to create a slug based on a field name 'title' (text input)
//to save in the field 'url' (text input)
//click on the button will automatically create the slug

//copy and paste the following code in the button handler
((btn)=>{

//get button id
const id = btn.id
//get button element
const button = document.getElementById(id);
//define the current DataObject as workspace in order to find the elements  
const workspace = '_data_object_name'; //ex. News
  
//find the root element of the record
const root = button.closest('div.pimcore_class_' + workspace);

//find the source input field by name with the value to slugify (in this example 'title')
const source = root.querySelector('input[name="title"]');
//find the targe input field by name with the slugified value (in this example 'url')  
const target = root.querySelector('input[name="url"]');

//set the target value with the slugified value
target.value = slugify(source.value);

function slugify(str)
{
