Javascript - 我看不到值總和的結果

Question

我在腳本中有一個設計問題，它給出了右列的值（忽略左邊的值），當我點擊“查看”時，我在綠色框中看不到sume的結果結果”

 // Old script /*window.sumInputs = function() { var inputs = document.getElementsByTagName('input'), result = document.getElementById('total'), sumar = 0; for(var i=0; i<inputs.length; i++) { var ip = inputs[i]; if (ip.name && ip.name.indexOf("total") < 0) { sumar += parseInt(ip.value) || 0; } } result.value = sumar; }*/ // ======================== // New script $(document).ready(function() { var valores = $('#derecha').children(); var suma = 0; $.each(valores, function() { valor = $(this).val() || 0; suma += parseInt(valor); }); //console.log(suma); valores = document.getElementById('total'); }); 

 body p { margin: 0 20px } /*#izquierda {display:none}*/ #izquierda, #derecha { display: inline-block; vertical-align: top; width: 140px; margin: 20px 20px 20px 20px; padding: 10px; border: 1px solid #000 } #izquierda span, #derecha span, body span { font-weight: bold } #izquierda p, #derecha p { margin: 5px auto 15px; text-align: center } input { width: 80px; display: block; margin: 5px auto; padding: 2px 0; background: #f2f2f2; border: none; border: 1px solid #000; text-align: center } #cont-resultado { text-align: center; width: 120px; padding-left: 40px } #cont-resultado input { display: inline-block; margin: 0 auto 10px; background: red; color: #fff; border: none; padding: 10px 0 } #cont-resultado a { display: inline-block; text-decoration: none; color: #fff; background: green; padding: 10px 12px } #total { display: block }

我究竟做錯了什么...？

提前致謝！

$(document).ready(function(){
var valores = $('#derecha').children();
var suma = 0;
$.each(valores,function(){
  valor = $(this).val() || 0;
  suma += parseInt( valor );
});

//console.log(suma);
valores = document.getElementById('total');

});

你沒有對suma做任何事情，進一步，為孩子使用選擇器.children('input') 。

 $(document).ready(function() { function sumInputs(e) { e.preventDefault(); var valores = $('#derecha').children('input'); var suma = 0; $.each(valores, function() { valor = $(this).val(); suma += Number(valor); }); valores = document.getElementById('total'); $(valores).val(suma); } $('#sumup').on('click', sumInputs); });

你需要將valores （新的）的值設置為suma ：

valores.val(suma);
