如何在HTML中找到localStorage的大小？
localStorage用于在多个会话之间保留信息。最大大小为5MB。
示例
您可以尝试运行以下代码片段以检查分配的大小-
var sum = 0;
//循环查看尺寸
for(var i in localStorage) {
var amount = (localStorage[i].length * 2) / 1024 / 1024;
sum += amount;
document.write( i + " = " + amount.toFixed(2) + " MB");
}
document.write( "Total = " + sum.toFixed(2) + " MB");
