页面刷新后保留选中多个单选按钮
[英]Retain Multiple Radio Buttons checked after page refresh
问题描述
在一种形式中，有2组单选按钮。
在名为Result的第一个组中，有4个选项：id =“ ok”，id =“ fa”，id =“ fp”，id =“ bp”。
在第二个名为ResultCategories的组中，有9个选项：id =“ cat1” .... id =“ cat9”。
我想要的是：
一种。 如果单击“确定”，则ResultCategories将被取消选中（如果已选中）。
湾 如果单击fp或bp，将检查ResultCategories的cat9。
C。 如果单击ResultCategories的cat1到cat8之一，将检查Result的fa。
d。 单击单选按钮时，页面将刷新，并且选中的单选按钮保持选中状态。
我到c工作，但d没有工作 。 它仅保留一组的选中的无线电。
这是尝试的方法：

我在这里添加了一个小提琴： 小提琴
$(document).ready(function() {
var result_dom = $('input[name="Result"]');
var categories_dom = $('input[name="ResultCategories"]');
var cat9 = $('#cat9');
var fa = $('#fa')
result_dom.on('change', function() {
var checked_val = $(this).val();
if (checked_val == 1) {
categories_dom.prop('checked', false);
} else if (checked_val == 3 || checked_val == 4) {
cat9.prop('checked', true);
}
});
categories_dom.on('change', function() {
var checked_val = $(this).val();
if (checked_val >= 1 && checked_val <= 8) {
fa.prop('checked', true);
}
});
});
$(document).ready(function(){
if(localStorage.selected) {
$('#' + localStorage.selected ).attr('checked', true);
}
$('.radio').click(function(){
localStorage.setItem("selected", this.id);
});
});
如何保留选中的两组单选按钮？
更新的代码：
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
var result_dom = $('input[name="Result"]');
var categories_dom = $('input[name="ResultCategories"]');
var cat9 = $('#cat9');
var fa = $('#fa')
result_dom.on('change', function() {
var checked_val = $(this).val();
if (checked_val == 1) {
categories_dom.prop('checked', false);
} else if (checked_val == 3 || checked_val == 4) {
cat9.prop('checked', true);
}
});
categories_dom.on('change', function() {
var checked_val = $(this).val();
if (checked_val >= 1 && checked_val <= 8) {
fa.prop('checked', true);
}
});
});$(document).ready(function() {
var result_dom = $('input[name="Result"]');
var categories_dom = $('input[name="ResultCategories"]');
var cat9 = $('#cat9');
var fa = $('#fa')
result_dom.on('change', function() {

if (checked_val == 1) {
categories_dom.prop('checked', false);
} else if (checked_val == 3 || checked_val == 4) {
cat9.prop('checked', true);
}
});
categories_dom.on('change', function() {
var checked_val = $(this).val();
if (checked_val >= 1 && checked_val <= 8) {
fa.prop('checked', true);
}
});
});
$(document).ready(function(){
//get the selected radios from storage, or create a new empty object
var radioGroups = JSON.parse(localStorage.getItem('selected') || '{}');
//loop over the ids we previously selected and select them again
Object.values(radioGroups).forEach(function(radioId){
document.getElementById(radioId).checked = true;
});
//handle the click of each radio
$('.radio').on('click', function(){
//set the id in the object based on the radio group name
//the name lets us segregate the values and easily replace
//previously selected radios in the same group
radioGroups[this.name] = this.id;
//finally store the updated object in storage for later use
localStorage.setItem("selected", JSON.stringify(radioGroups));
});
});
