Is there a way to fire jquery only once when resizing? I have here a script that adds a hash(#) within the href of an anchor <a> element. The problem is the script keeps when resizing and so it keeps adding hash within the href. Is there a way to make it fire only once?

(function($)
 'use strict';



 var mobileMenuDrawer = 

 init : function() 

 $('.region-primary-menu').addClass('primary-mobile-menu');
 $('.primary-mobile-menu .menu.-primary > .menu-item').addClass('mobile-menu-item');
 $('.primary-mobile-menu .menu.-primary > .mobile-menu-item > .link').off('click').on('click', function() 
 $(this).closest('.mobile-menu-item').toggleClass('-active');
 )
 ,

 clear : function() 
 $('.primary-mobile-menu, .mobile-menu-item').removeClass('primary-mobile-menu mobile-menu-item');
 
 

 var addHash = 

 init : function() 

 if ($('.region-primary-menu').hasClass('primary-mobile-menu')) 

 $('.primary-mobile-menu .mobile-menu-item > .link').each(function() 
 // console.log($(this).attr('href'));
 let currentUrl = $(this).attr('href');

 $(this).prop('href', '#' + currentUrl);

 // this.href = '/#/' + this.href;
 // window.location.hash = $(this).attr('href');
 );
 

 else 

 $('.primary-mobile-menu .mobile-menu-item > .link').each(function() 

 $(this).removeAttr('#');

 );

 
 
 


 $(document).ready(function() 

 if ($(window).outerWidth() <= 1024) 
 mobileMenuDrawer.init();
 

 else 
 mobileMenuDrawer.clear();
 

 addHash.init();


 );

 $(window).on('resize', function() 

 if ($(window).outerWidth() <= 1024) 
 mobileMenuDrawer.init();
 addHash.init();
 

 else 
 mobileMenuDrawer.clear();
 
 );



)(jQuery)

Yes. Just put a flag checking if the property already exists:

if(!$(this).prop('href')) 
 $(this).prop('href', '#' + currentUrl);

Or if the property is similar:

if($(this).prop('href') != '#' + currentUrl) 
 $(this).prop('href', '#' + currentUrl);

Or if the property is empty (will only work if the property already exists):

if($(this).prop('href') == "") 
 $(this).prop('href', '#' + currentUrl);

If you want to prevent the entire codeblock from executing. You could use some sort of custom flag that you need to flick to the opposite boolean value once a desired operation has been completed. You could make this a variable in your local function scope or make it a property of the addHash object. I'll do the former in this one.

 let isOk = false;

 var addHash = 

 init : function() 
 if(isOk) return;

 if ($('.region-primary-menu').hasClass('primary-mobile-menu')) 

 $('.primary-mobile-menu .mobile-menu-item > .link').each(function() 
 let currentUrl = $(this).attr('href');

 $(this).prop('href', '#' + currentUrl);
 isOk = true;
 );
 
 

Note: You should stop using var.
