I am trying to remove all the even numbered items from my array with this code:
var myArray = [1,2,3,4,5,6];
myArray.forEach(function(item) {
if (item%2 == 0) {
myArray.splice(item);
}
});
I think where im getting it wrong is with the splice?
you can do like this :
var myarray = [1,2,3,4,5,6]
filtered = myarray.filter(function(el, index) {
return index % 2 === 1;
});
output : [2, 4, 6]
You should do it this way:
var myArray = [1,2,3,4,5,6];
myArray.forEach(function(item, x) {
if (item%2 == 0)
myArray.splice(x, 1); // Remove 1 item from index x
});
Or the better way to use .filter (IE8+)
var myArray = myArray.filter(function(item) {
return item % 2 ==0 ? false : true; // Return false if item is even and true other way round.
});
yes, splice is done by index
var myArray = [1,2,3,4,5,6];
myArray.forEach(function(item) {
if (item%2 == 0) {
var index = myArray.indexOf(item);
myArray = myArray.splice(index,1);
}
});
filter() would be better
var arr = myArray.filter(function(item) {
return item % 2 ==0 ? true : false;
});
