Empty an array when function triggered

Question

var names = {};

// PUTTING DATA TO tmpChatters output example is.

[ { name: 'aaa', age: '', sex: 'man'},
  { name: 'bbb', age: '', sex: 'female'} ]


function deleteFunction(currentName) {

}
deleteFunction('aaa');

So deleteFunction must empty where names eqauls the name inside the object. How do i need to do this ?

So you don't want to EMPTY the array, you want to delete the object where `name` is `aaa`, correct? — PlantTheIdea, Mar 25 '15 at 18:34

So you are deleting a single object from an array of objects based on the value contained in an arbitrary field in the the object? — Mike Brant, Mar 25 '15 at 18:36

Just loop over it and slice the object out of the array:

for(var i = yourArray.length; i--;){
    if(yourArray[i].name === currentName){
        yourArray.splice(i,1);
        break;
    }
}

Should give you what you want. If there can be multiple names that match, just remove the break to loop over them all.

Shouldn't it be `yourArray = yourArray.slice(i,1);`? – i-- Mar 25 '15 at 18:40
This make the whole object empty – Inna Mar 25 '15 at 18:55
@inna - i messed up, this should have been `splice` instead of `slice` ... i had a typo originally and it cascaded. oh well, the OP got the answer they wanted. – PlantTheIdea Mar 25 '15 at 19:17

Try it as a forEach();

   names.forEach(function(a, b){
        if(curretNick === a.name){
            names.splice(b, 1);
        }
    });
