How To Apply Ajax To Get Data In Dropdown?

i am using django as a backend to query my result.Like i have three dropdown and in my views I am using the value from first two drop down to bind the data in third dropdown. I kno

Solution 1:

Are you trying to retrieve some data to use in the third select? You can do this:

$.ajax({
   url: 'The url to the view',
   type: 'GET', //Use POST if database modification would occurdata: {
         'first_select': $('#first-select').val(),
         'second_select': $('#second-select').val()
   },
   success: function(data){
          //data contains whatever your view returns. If it's html, then add it to the select directly like $('#select').html(data); but if it's json response, Use it as you wish
   },
   error: function(xhr){
       alert(xhr.status + ": " + xhr.responseText);
   }
})

I'd recommend that you add this just before closing the body tag on your page and not within the page. You may define some {% block script %}{% endblock %} in the base template that you've inherited and override that block to add your scripts in there.
