sessionstorage 怎么存储一个json

Question

如题所述

Answer 1

storage只能存储字符串的数据，对于JSON中常用的数组或对象却不能直接存储。
<code class="hljs nix">var <span class="hljs-variable">obj = { name:'Jim' };
sessionStorage.<span class="hljs-variable">obj = obj;
localStorage.<span class="hljs-variable">obj = obj;

var <span class="hljs-variable">arr = [<span class="hljs-number">1,<span class="hljs-number">2,<span class="hljs-number">3];
sessionStorage.<span class="hljs-variable">obj = arr;
localStorage.<span class="hljs-variable">obj = arr;</span></span></span></span></span></span></span></span></span></code>
