I'm creating an event registration page.
On this page, users need to be able to search for a database item so it can be registered to this event. Therefore, the POST request must be submitted to a different URL than what the user is on, so that it doesn't interfere with the form wizard sequence.
This is my javascript:
(document).ready(function() {
$('#primary_artist_lookup').on('input', function(){
console.log("Listener success");
var searchItem = $('#primary_artist_lookup').val();
$.ajax({
url : $('#lookupLink').val(),
type : "POST", //http method
data : searchItem,
dataType: "json",
// handle a successful response
success : function (json) {
console.log(json); // log the returned json to the console
console.log("success"); // another sanity check
},
// handle a non-successful response
error : function(xhr,errmsg,err) {
$('#results').html("<div class='alert-box alert radius' data-alert>Oops! We have encountered an error: "+errmsg+
" <a href='#' class='close'>×</a></div>"); // add the error to the dom
console.log(xhr.status + ": " + xhr.responseText); // provide a bit more info about the error to the console
}
});
});
The url is a hidden html value that maps to the url I am trying to POST the data to:
<p hidden id="lookupLink">{% url "Users:lookup" %}</p>
There is an additional js portion to submit a CSRF token to Django for security purposes:
// CSRF VALIDATION //
// This function gets cookie with a given name
function getCookie(name) {
var cookieValue = null;
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = jQuery.trim(cookies[i]);
// Does this cookie string begin with the name we want?
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
break;
}
}
}
return cookieValue;
}
var csrftoken = getCookie('csrftoken');
/*
The functions below will create a header with csrftoken
*/
function csrfSafeMethod(method) {
// these HTTP methods do not require CSRF protection
return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
function sameOrigin(url) {
// test that a given url is a same-origin URL
// url could be relative or scheme relative or absolute
var host = document.location.host; // host + port
var protocol = document.location.protocol;
var sr_origin = '//' + host;
var origin = protocol + sr_origin;
// Allow absolute or scheme relative URLs to same origin
return (url == origin || url.slice(0, origin.length + 1) == origin + '/') ||
(url == sr_origin || url.slice(0, sr_origin.length + 1) == sr_origin + '/') ||
// or any other URL that isn't scheme relative or absolute i.e relative.
!(/^(\/\/|http:|https:).*/.test(url));
}
$.ajaxSetup({
beforeSend: function(xhr, settings) {
if (!csrfSafeMethod(settings.type) && sameOrigin(settings.url)) {
// Send the token to same-origin, relative URLs only.
// Send the token only if the method warrants CSRF protection
// Using the CSRFToken value acquired earlier
xhr.setRequestHeader("X-CSRFToken", csrftoken);
}
}
});
return false;
});
When I try to use this ajax function, it doesn't post to the url I request, but rather the page that the users are on. What am I doing wrong?

use text()
instead:
url : $('#lookupLink').text(),
and data should be an object:
data : { searchItem : searchItem },
