Javascript Hooks
To register javascript hooks, use the WPD.Hooks javascript object methods addFilter and removeFilter
/**
* Adds a callback function to a specific programmatically triggered tag (hook)
*
* @param tag - the hook name
* @param callback - the callback function variable name
* @param priority - (optional) default=10
* @param scope - (optional) function scope. When a function is executed within an object scope, the object variable should be passed.
*/
WPD.Hooks.addFilter = function( tag, callback, priority, scope )
/**
* Removes a callback function from a hook
*
* @param tag - the hook name
* @param callback - the callback function variable
*/
WPD.Hooks.removeFilter= function( tag, callback )

Usage

// Add regular function
let func1 = funtion(arg1, arg2) {
return 'my value';
}
WPD.Hooks.addFilter('hook_name', func1);
// Add an object method, with reference to "this" inside the method
let myObject = {
'myValue': 'my value',
'myFunction': function(arg1, arg2) {
return this.myValue;
}
};
WPD.Hooks.addFilter('hook_name', myObject.myFunction, 10, myObject);
// Anonymous function
WPD.Hooks.addFilter('hook_name', function(arg1, arg2){
return 'my value';
});
// To remove all hooks
WPD.Hooks.removeFilter('hook_name');
