Using Splice to Remove Array Elements in JavaScript
var productIds = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];
var removed = productIds.splice(2,2);
var list = ["bar", "baz", "foo", "qux"];
list.splice(0, 2);
// Starting at index position 0, remove two elements ["bar", "baz"] and retains ["foo", "qux"].
Removing Array Items By Value Using Splice
var productIds = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];
for( var i = 0; i < productIds.length; i++){
if ( productIds[i] === 5) {
productIds.splice(i, 1);
}
}
//=> [1, 2, 3, 4, 6, 7, 8, 9, 0]
var productIds = [1, 2, 3, 4, 5, 5, 6, 7, 8, 5, 9, 0];
for( var i = 0; i < productIds.length; i++){
if ( productIds[i] === 5) {
productIds.splice(i, 1);
i--;
}
}
//=> [1, 2, 3, 4, 6, 7, 8, 9, 0]
Using the Array filter Method to Remove Items By Value
var productIds = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];
var filtered = productIds.filter(function(value, index, arr){
return value > 5;
});
//filtered => [6, 7, 8, 9]
//productIds => [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
The Lodash Array Remove Method
var productIds = [1, 2, 3, 4];var evens = _.remove(productIds, function(n) { return n % 2 === 0;});console.log(productIds);// => [1, 3]console.log(evens);// => [2, 4]
Making a Remove Method
function arrayRemove(productIds, value) {
return productIds.filter(function(ele){
return ele != value;
});
}
var result = arrayRemove(array, 6);
// result = [1, 2, 3, 4, 5, 7, 8, 9, 0]
Explicitly Remove Array Elements Using the Delete Operator
var productIds = [1, 2, 3, 4, 5, 6];
delete productIds[4]; // delete element with index 4
console.log( productIds );
// [1, 2, 3, 4, undefined, 6]
alert( productIds );
// 1,2,3,4,,6
Clear or Reset a JavaScript Array
var productIds = [1, 2, 3, 4, 5, 6]; //do stuffar = []; //a new, empty array!
Example
var productIds = [1, 2, 3, 4, 5, 6];
var productIds2 = productIds;
// Reference productIds by another variable productIds = [];
console.log(productIds2);
// Output [1, 2, 3, 4, 5, 6]
Example
var productIds = [1, 2, 3, 4, 5, 6]; console.log(productIds); // Output [1, 2, 3, 4, 5, 6] productIds.length = 0; console.log(productIds); // Output []
Example
var productIds = [1, 2, 3, 4, 5, 6]; console.log(productIds); // Output [1, 2, 3, 4, 5, 6] productIds.splice(0, productIds.length); console.log(productIds); // Output []
Example
var productIds = [1, 2, 3, 4, 5, 6];
console.log(productIds);
// Output [1, 2, 3, 4, 5, 6]
while (productIds.length) {
productIds.pop();
}
console.log(ar);
// Output []
