从 json 阵列 javascript 中删除整个 object

Question

I have a json array like the picture below

The position for marker 1 is Null, how can i remove the entire marker 1 object from the array so i only have marker 2,3 and 4 left in the array? thank you

Answer 1

jsonArray = jsonArray.filter(item => !item.position.includes(null))

Or

jsonArray = jsonArray.filter(item => item.position[0] !== null && item.position[1] !== null)

Answer 2

You could do something like:

const result = arrayOfObjects.filter((object) => {
  return object.position[0] !== null && object.position[1] !== null);
}

Answer 3

We can use a library lodash and using filter method, like this:

var items = _.filter(items, function(item){return item.position});

or

var items = _.filter(items, function(item){return item.position !== null && item.position !== ""});

we can filter out objects which do have position null

Answer 4

Try this code:

const filtered = array.filter(items => items.position[0] != null || items.position[1] != null);
console.log(filtered);
