将表单数据保存到本地存储并在刷新时显示 [英] Saving form data to local storage and show it on refresh
问题描述
我正在制作一个表单，用户可以输入他们的数据。我希望通过本地存储来保存这个日期。但是当我刷新页面时，只记得身高和体重。
I am making a form where users can input their data. I'd like for this date to be saved by use of local storage. But when i refresh the page only height and weight are still remembered. And i have been quite stuck on trying to make gender , sportivity and birthdate be remembered as well.

推荐答案
您的脚本很复杂。尝试这个。正在工作 JSFIDDLE
You are complicating your script. Try this. Working JSFIDDLE
如果您使用jQuery一次，请不要将它与纯JavaScript混合使用，如 document.getElementById（）。并且不要创建 height 变量来存储 $（'＃height'）。val（），你可以直接使用这个。代码更易读。
If you are using jQuery once, do not mix it with pure javascript, like document.getElementById(). And do not create a height variable to store the $('#height').val(), you can use this directly. Code is more readable.
$(document).ready(function() {
$(window).unload(saveSettings);
loadSettings();
});
function loadSettings() {
$('#height').val(localStorage.height);
$('#weight').val(localStorage.weight);
$('#dateOfBirth').val(localStorage.dateOfBirth);
$('input[value="' + localStorage.gender + '"]').prop('checked', true);
$("#sportive").val(localStorage.sportive);
}
function saveSettings() {
localStorage.height = $('#height').val();
localStorage.weight = $('#weight').val();
localStorage.dateOfBirth = $('#dateOfBirth').val();
localStorage.sportive = $("#sportive").val();
localStorage.gender = $('input[type=radio]:checked').val();
}
