"ploads/2022/08/Offer-Image-Intro-647-x-742-E.jpg&quote= 

can someone help?

I know the concept of split() and filter(), but don't know to use the to only select whatsapp

this is my piecd of code:

jQuery('div.share_block > div > a').click(function(){
var _shareLink =jQuery(this).attr('href').filter() === "whatsapp";
var visit_link= jQuery(this).prevUntil('div.offer_hover_block > a').text();
  
window.dataLayer = window.dataLayer || [];
    window.dataLayer.push({
      'event': 'whatsapp_click',
      'carouselHref' : _shareLink,
      'pageName' : visit_link
    });
  });

EDITED: I just want to filter out whatsapp. my code above has a var shareLink which prints out the whole whatsapp link. i want to add a function to just filter out whatsapp

Based on your code, it appears you are trying to test if whatsapp string is part of the URL. Consider the following.

jQuery('div.share_block > div > a').click(function(){
  var _shareLink = (jQuery(this).attr('href').indexOf("whatsapp") > -1);
  var visit_link = jQuery(this).prevUntil('div.offer_hover_block > a').text();
  window.dataLayer = window.dataLayer || [];
  window.dataLayer.push({
    'event': 'whatsapp_click',
    'carouselHref' : _shareLink,
    'pageName' : visit_link
  });
});

The indexOf() method returns the first index at which a given element can be found in the array, or -1 if it is not present.

If you have a URL like:

https://api.whatsapp.com/send?text=ploads/2022/08/Offer-Image-Intro-647-x-742-E.jpg&quote= 

And an expression like:

var _shareLink = jQuery(this).attr('href').indexOf("whatsapp");

The value of _shareLink will be:

12

You can then use this as a logical statement to get true or false .
