I am trying to delete the items from my localstorage I render the table data on the screen but my table data is coming into the localstorage i want to delete particular item for example:
if i have localstorage just like that
0: {namex: "ANUJ", lnamex: "ANUJ", emailx: "anuj123@gmail.com"}
1: {namex: "ANUJ", lnamex: "ANUJ", emailx: "anuj123@gmail.com"}
2: {namex: "ANUJ", lnamex: "ANUJ", emailx: "anuj123@gmail.com"}
3: {namex: "ANUJ", lnamex: "ANUJ", emailx: "anuj123@gmail.com"}
4: {namex: "ANUJ", lnamex: "ANUJ", emailx: "anuj123@gmail.com"}
5: {namex: "ANUJ", lnamex: "ANUJ", emailx: "anuj123@gmail.com"}
6: {namex: "rohit", lnamex: "ANUJ", emailx: "anuj123@gmail.com"}
let say I want to delete 6 items. How can i do so or if i delete it when I refresh the page it come again
You can remove localstorage item with this method:
//setting item
localStorage.setItem('image', 'myCat.png');
//removing item
localStorage.removeItem('image'); function example(){
let array = [
{namex: "1", lnamex: "ANUJ", emailx: "anuj123@gmail.com"},
{namex: "2", lnamex: "ANUJ", emailx: "anuj123@gmail.com"},
{namex: "3", lnamex: "ANUJ", emailx: "anuj123@gmail.com"},
{namex: "4", lnamex: "ANUJ", emailx: "anuj123@gmail.com"},
{namex: "5", lnamex: "ANUJ", emailx: "anuj123@gmail.com"},
{namex: "6", lnamex: "ANUJ", emailx: "anuj123@gmail.com"}
];
localStorage.setItem('text32', JSON.stringify(array));
let getDataFromLocalStorage = JSON.parse(localStorage.getItem("text32")); //convert your saved string array to object
let result = getDataFromLocalStorage.filter((x, idx) => idx != 1);
document.getElementById('ex').innerHTML = JSON.stringify(result)
}
You have to save your array as a string in local Storage so you have to get it back and convert it to Object and use filter() method. it will give all the data except 1th index object according to above example
if you want to remove 6th one you have to send the index number as 5 because array objects are start form 0th index
then save it back to local storage as a string if you want
