我正在尝试使用jquery在localstorage中存储一个对象,但似乎无法获得不同的结果:[object Object]。
例如,我如何能够在下面的代码中登录国家?
<html>
<head>
<script src="https://code.jquery.com/jquery-3.3.1.js" integrity="sha256-2Kok7MbOyxpgUVvAk/HJ2jigOSYS2auK4Pfzbm7uH60=" crossorigin="anonymous"></script>
</head>
<input type="text" id="text">
<button value="save" onClick="setStorage()" id="btn"> Save </button>
<script>
function setStorage(){
var text = $("#text").val();
testobj = {'country' : 'testcountry', 'population' : 3}
localStorage.setItem('storage', {'text' : testobj});
var retreived = localStorage.getItem('storage');
console.log('retreived : ' + retreived);
}
</script>

localStorage
存储字符串。出于这个原因,我在将对象等存储到存储时存储JSON,在存储时使用JSON.stringify
,在检索时使用JSON.parse
:
function setStorage(){
var text = $("#text").val();
testobj = {'country' : 'testcountry', 'population' : 3}
localStorage.setItem('storage', JSON.stringify({'text' : testobj}));
var retreived = JSON.parse(localStorage.getItem('storage'));
console.log('retreived : ' + retreived);
}
