how to pass $(this).data() in ajax request

Time:10-05

i need to pass $(this).data into success func in ajax. here is my code

var product_id = $(this).data("product_id");

var url = "{{ route('client.add_wishlist')}}";

$.ajax({
  url: url,
  type: "POST",
  dataType: "json",
  data: {
    product_id: product_id,
    _token: "{{ csrf_token() }}",
  },
  success: function (data) {
    $(this).addClass("wishlist-comp-saved");
  },
});

But $(this).addClass('wishlist-comp-saved'); is not working inside success: function(data) {}

CodePudding user response:

$(this) will change context when called. When inside of the success: function (data), $(this) is not the same as it was inside of whatever is calling this $.ajax() request.

For your issue, you simply have to set $(this) as a variable before your $.ajax() request, and reference it in the success: function():

var product_id = $(this).data("product_id");
var url = "{{ route('client.add_wishlist')}}";

var that = $(this);
$.ajax({
  url: url,
  type: 'POST',
  dataType: "json",
  data: {
    'product_id': product_id
    '_token': "{{ csrf_token() }}"
  },
  success: function(data) {
    that.addClass('wishlist-comp-saved');
  }
});
