I am trying to iterate an object that I get in Angular but I was unable to. In order to understand that I tried it simply using below code:
<script>
var x = {"data":['A','B','C']};
for(v in x)
{
alert(v[0]);
}
</script>
The output of this is "d".How can I output "A"?
If you use this for loop, this is the syntax:
var x = {"data":['A','B','C']};
for(var key in x)
{
alert(key); //data
alert(x[key]); //A,B,C
}
This is plain JS though, no Angular.
You can add further if
clauses to receive the first element like A
, but make sure it doesn't error out on other properties of the object.
