Please made changes in your JS code at success call back. Because data.item is undefined.

There is no item key on that json response.

<script> $.getJSON("url", { tags : "dogs", tagmode : "any", format : "json" }, function(data) { console.log("length" + data.length); $.each(data, function(i, item) { }); }); </script>

How can i parse and display each "title" from the JSON?

power_scriptor Over a year ago

Need to use one more each inside first each.

$.each(data, function (outKey, outerObjVal) { 	$.each(outerObjVal, function (innerKey, innerObjVal) { 		console.log(innerObjVal.title); 	}); });

If you got solution, accept my answer
