根据用户选择的值的动态数量分配单选按钮的值

Question

用户选择五个选择下拉列表后，我想根据最多 3个用户选择设置字段"radio_btn_name"中的单选按钮的值。将每个对象视为一个"规则"。如果选择组合与该规则匹配，请为"radio_btn_x"提供"输出"值。

在我问题的第 1 部分中，当"selected_option_names_"的数量等于选择下拉列表的数量时，我达到了我想要的结果。但是，我需要能够针对最多 3个用户选择检查动态数量的下拉列表。

我想解决方案将与第 1 部分大不相同，因此我觉得有必要提出一个新问题。

$(document).ready(function() {
// A successful solution would render all these rules true, radio_button_4, 
// radio_button_8 and radio_button_1 would get their respective new values
var objs = [{
selected_option_name_1: "select_1",
selected_option_name_2: "",
selected_option_name_3: "",      
selected_option_value_1: "1-1",

// Solution for part 1. Will only work if number of dropdowns == "selected_option_name_"
$("#submit").on("click", function() {
$("#wrapper").find("input[type='radio']").each(function(i, o) {
var btn = $(this);
var btn_name = $(this).attr("name");
$.each(objs, function(index, rule) {
if (btn_name == rule.radio_btn_name) {
if(rule.selected_option_value_1 == $('#select_1').val()

&& rule.selected_option_value_3 == $('#select_3').val()) {
btn.val(rule.output);
console.log(rule.output);

Answer 1

事实证明，解决方案并不像我想象的那么遥远。我只需要添加一个隐藏的输入类型，名称等于空字符串，以考虑对象中的任何空字符串。

我还更新了我的jQuery，以从我帖子的第一部分找到名称与id的值。

更新的小提琴

$(document).ready(function() {
$("#submit").on("click", function() {
$("#wrapper").find("input[type='radio']").each(function(i, o) {
var btn = $(this);
var btn_name = $(this).attr("name");
$.each(objs, function(index, rule) {
if (btn_name == rule.radio_btn_name) {
if(rule.selected_option_value_1 == $('[name="'+rule.selected_option_name_1 + '"]').val()
&& rule.selected_option_value_2 == $('[name="'+rule.selected_option_name_2 + '"]').val()
&& rule.selected_option_value_3 == $('[name="'+rule.selected_option_name_3 + '"]').val()) {
btn.val(rule.output);
console.log(rule.output);
}
}
});
});
});
});

<div>
<input type="hidden" name="" value="">
<button id="submit">Submit</button>
</div>
