如标题所说，有没有办法在Javascript中按类获取数组中的输入值？我正在尝试使用类名称获取每个输入值，并将其存储在这样的数组中
$(document).ready(function(){
$("#Scal").click(function() {
var map = [];
$('input').each(function() {
map[$(this).attr('class="Sc"')] = $(this).val();
});
alert(map.Sc1);
});
});<!doctype html>

更新：-我已经添加了我的HTML代码。我想要的是获取学分的每个输入框，并将其存储在使用类的数组中
此创建<className，arrayOfInputs>映射：
var map = {};
$('input').each(function() {
var $this = this;
($this.className||'').split(/\s+/).forEach(function(className){
if(!map[className]) map[className] = [];
map[className].push($this);
})
});
这收集了select价值
var map = {};
$('input[class="Sc"]').closest('ul').find('select').each(function(){
map[$(this).attr('name')] = $(this).val();
});
这input使用输入name作为键来收集值
var map = {};
$('input[class="Sc"]').each(function(){
map[$(this).attr('name')] = $(this).val();
});
