TypeError: stepUp called on an object that does not implement interface HTMLInputElement

Question

I have this code

<a data-remote="true" data-box_no="1" class="find_or_add_horse" href="#">Find/Add Horse</a> 

And I do ajax call when I click one the link

$(document).on('click', '.find_or_add_horse', function () {         var search_term = $(this).parents('.sub-middle-column').find('.search_horse');         var box_no = $(this).data('box_no');           $.ajax({             url: "/startup_wizard/find_horse",             dataType: 'script',             type: 'GET',             data: { box_no: box_no, search_term: search_term}         });         return false;       }); 

But when I click on the link I get this error "TypeError: 'stepUp' called on an object that does not implement interface HTMLInputElement" when I remove this code from ajax call

data: { box_no: box_no, search_term: search_term} 

my code just work fine. Why this is happening and how to fix this? How can I send the data?

Answer 1

If search_term is an input field you might want to get its value.

var search_term = $(this).parents('.sub-middle-column').find('.search_horse').val(); 

Right now you are referencing a jQuery Object containing a HTMLDom-Element but I think what you want is the string inside the search input element.

Answer 2

TypeError: stepUp called on an object that does not implement interface HTMLInputElement comes when you forget # sign for(id) and . sign for class. when we can get value directly without . or # sign.

Wrong method: - var email = $('PHMC_email').val();

Correct Method:

-var email = $('#PHMC_email').val(); Or var email = $('.PHMC_email').val();
