我有一个表单部分,人们可以在其中添加他们的电子邮件地址。
我有几个问题:
(1)在提交电子邮件地址时,页面会刷新(我知道如果没有ajax或异步解决方案,这是不可避免的)。不过,这会引起第二个问题,
(2)我似乎无法将这些电子邮件保存为数组,并使用JSON.parse(localStorage.getItem('EmailsStuff'))
将其显示出来
我的JS/Jquery的一部分
var total = [];
$(document).on("click", ":submit", function(e) {
var stuff = ($($email).val())
total = [JSON.stringify(stuff)];
localStorage.setItem('EmailsStuff', JSON.stringify(total));
});
和html:
<form class="newsletter">
<input type="email" value="" placeholder="Join Update List Here" class ="newsletter-email" />
<input type="submit" value="Thanks!" class="newsletter-email" id="fast"/>
</form>
如果我取样:
localStorage.setItem('sample',JSON.stringify(["bob", "susan", "rafiki"]);
因此读作
JSON.parse(localStorage.getItem('sample'));
最佳答案
您的电子邮件输入选择器似乎错误,请尝试将其更改为:
var stuff = $('#email').val();
输入一个id:
<input id="email" type="email" value="" placeholder="Join Update List Here" class ="newsletter-email" />

编辑:
如果要保留以前输入的所有电子邮件地址,并在每次提交表单时将其添加到此数组中,可以执行以下操作:
$(document).on("click", ":submit", function(e) {
var stuff = ($('#email').val());
// Load emails
var emails = JSON.parse(localStorage.getItem('EmailsStuff'));
if (emails) {
// If the item exists in local storage push the new email address to the array and and save
emails.push(stuff);
localStorage.setItem('EmailsStuff', JSON.stringify(emails));
} else {
// If the item doesn't exist in local storage set the item to a new array containing new email address
localStorage.setItem('EmailsStuff', JSON.stringify([stuff]));
}
});
$(document).on("click", "#loadEmail", function(e) {
alert(JSON.parse(localStorage.getItem('EmailsStuff')));
});
