Kubadilisha Miundo Iliohifadhiwa katika localStorage kwa JavaScript

Acha kwenye kuhifadhi dhabiti kuhifadhiwe safu fulani:

javascriptlet arr = [1, 2, 3, 4, 5];
localStorage.setItem('data', JSON.stringify(arr));

Acha sasa hitaji litakaje la kubadilisha safu hii, kwa mfano, kuongeza kipengele kingine mwishoni au kubadilisha kipengele kilichopo tayari.

Kutatua tatizo hili, tutapata mnyororo uliohifadhiwa kwenye hifadhi na safu, tubadilishe mnyororo huu kuwa safu, tufanye mabadiliko yanayohitajika kwenye safu hii, tubadilishe safu hii tena kuwa mnyororo na tuandike tena kwenye hifadhi:

javascriptlet json = localStorage.getItem('data');
let data = JSON.parse(json);

data.push(6);
data[0] = '!';

localStorage.setItem('data', JSON.stringify(data));

javascriptlet users = [
  {
    surn: 'surn1',
    name: 'name1',
    age: 31,
  },
  {
    surn: 'surn2',
    name: 'name2',
    age: 32,
  },
  {
    surn: 'surn',
    name: 'name3',
    age: 33,
  },
];
