I'm trying to add error function to my ajax

Console.log error

script.js:255 Uncaught SyntaxError: Unexpected token (

line 255 would be error:function(error){ not sure why it won't read my code.

Answer 1

Error function is part of the AJAX and hence it needs to be inside it. Try this below code:

 function getWikiData(marker) { var wikiurl = "https://en.wikipedia.org/w/api.php? action = opensearch & search = " + marker.title + "&format=json&callback=wikiCallback"; $.ajax({ url: wikiurl, dataType: "jsonp", // jasonp: "callback", success: function(response) { var summary = response[2][0]; var article = response[3][0]; var articleUrl = article; console.log(response); console.log(response[2][0]); console.log(response[3][0]); self.infoWindow.setContent('<h2>' + marker.title + '</h2><p>' + summary + '</p>' + '<a title="go to wikipedia article" href="' + articleUrl + '">> go to wikipedia article</a>'); self.infoWindow.open(map, marker); }, error: function() { alert("An Error Occurred Loading Wikipedia Article. Please try again later ") } }); } 

Answer 2

Your error:function() was outside of ajax call. move error function to inside ajax call

 function getWikiData(marker) { var wikiurl = "https://en.wikipedia.org/w/api.php?action=opensearch&search=" + marker.title +"&format=json&callback=wikiCallback"; $.ajax({ url: wikiurl, dataType: "jsonp", // jasonp: "callback", success: function(response) { var summary = response[2][0]; var article = response[3][0]; var articleUrl = article; console.log(response); console.log(response[2][0]); console.log(response[3][0]); self.infoWindow.setContent('<h2>' + marker.title + '</h2><p>' + summary + '</p>' + '<a title="go to wikipedia article" href="' + articleUrl + '">> go to wikipedia article</a>'); self.infoWindow.open(map, marker); }, error: function(){ alert("An Error Occurred Loading Wikipedia Article. Please try again later") } }); }
