jQuery - Remove object from array

Question

I'm trying to remove an object from an array with

delete array[index]

which is deleting the object from the array however the .length property of the array is still == 1

Any ideas?

PS I'm trying to delete a question e.g. topic->questions[question_id]

enter image description here

if(topic_array[topic_id] !== 'undefined'){
 if(topic_array[topic_id].questions.length > 0){
 for(var i = 0; i < topic_array[topic_id].questions.length; i++){
 if(topic_array[topic_id].questions[i].question_id == question_id){
 delete topic_array[topic_id].questions[i];
 console.log(topic_array);
 }
 }
 }
 }

You don't want delete, you want splice:

topic_array[topic_id].questions.splice(i, 1);

• Garbit: topic_array[topic_id].questions.splice(i, 1) (splice on the questions array). Many thanks Elliot
