Question

我想为多个输入字段创建一个自动计算数组。问题是，自动计算的工作方式与第1行的魅力相似，但不适用于第2行和第3行。我想有15排。

任何帮助都将不胜感激。

<script type="text/javascript">
function calc(){
var textValue10 = document.getElementById('input10').value;
var textValue9 = document.getElementById('input9').value;
var textValue8 = document.getElementById('input8').value;
var textValue7 = document.getElementById('input7').value;
var textValue6 = document.getElementById('input6').value;
var textValue5 = document.getElementById('input5').value;
var textValue4 = document.getElementById('input4').value;
var textValue3 = document.getElementById('input3').value;
var textValue2 = document.getElementById('input2').value;
var textValue1 = document.getElementById('input1').value;
document.getElementById('output').value = (textValue10*10) + (textValue9*9) + (textValue8*8) + (textValue7*7) + (textValue6*6) + (textValue5*5) + (textValue4*4) + (textValue3*3) + (textValue2*2) + (textValue1*1);

Answer 1

问题很简单，HTML元素只能有一个唯一的id。你为多个元素提供了相同的ID。

Javascript getElementById方法只会选择具有给定id的第一个元素，而忽略其余元素。

这就是你的第一行像魅力和休息一样被忽略的原因。

为每个元素尝试不同的ID。或者为每行指定一个唯一的类时使用getElementsByClassName方法。

<html>

<head>
    <script type="text/javascript">
        function calc() {
            var row1 = document.getElementsByClassName('row1');
            var row2 = document.getElementsByClassName('row2');
            var row3 = document.getElementsByClassName('row3');
            document.getElementById('output1').value= clacARow(row1);
            document.getElementById('output2').value = clacARow(row2);
            document.getElementById('output3').value = clacARow(row3);
        
            
        }

        function clacARow(row){
            var output = 0;

            for(var i=0; i<row.length;i++){
                var value = (row[i].value)*(row.length-i);
                console.log(i)
                if(value){
                    output = output + value;
                }
            }
            console.log(output);
            return output;
        }
    </script>

Answer 2

您可以使用querySelectorAll DOM来动态完成计算。

＆＃13;

function calc(rowNumber){
var cells = document.querySelectorAll("#table tr:nth-child("+(rowNumber+2)+") td");

var sum = 0;
for (var i = 0; i < cells.length; i++) {
   var val = parseFloat(cells[i].firstChild.value) * (10 - i);
   if (!isNaN(val)) {
      sum+=val;
   }
}
cells[10].firstChild.value = sum;
 }

＆＃13;

<table id="table">
  <tr>
  <td>10</td>
  <td>9</td>
  <td>8</td>
  <td>7</td>
  <td>6</td>
  <td>5</td>
  <td>4</td>
  <td>3</td>
  <td>2</td>
  <td>1</td>
  <td>Total</td>
  </tr>
  
  <tr>
  <td><input size="8" onkeyup="calc(0)"value=""></td>
  <td><input size="8" onkeyup="calc(0)"value=""></td>
  <td><input size="8" onkeyup="calc(0)"value=""></td>
  <td><input size="8" onkeyup="calc(0)"value=""></td>
  <td><input size="8" onkeyup="calc(0)"value=""></td>
  <td><input size="8" onkeyup="calc(0)"value=""></td>
  <td><input size="8" onkeyup="calc(0)"value=""></td>
  <td><input size="8" onkeyup="calc(0)"value=""></td>
  <td><input size="8" onkeyup="calc(0)"value=""></td>
  <td><input size="8" onkeyup="calc(0)"value=""></td>
  <td><input size="8" value="" id="total"></td>
  </tr>
  <tr>
  <td><input size="8" onkeyup="calc(1)"value=""></td>
  <td><input size="8" onkeyup="calc(1)"value=""></td>
  <td><input size="8" onkeyup="calc(1)"value=""></td>
  <td><input size="8" onkeyup="calc(1)"value=""></td>
  <td><input size="8" onkeyup="calc(1)"value=""></td>
  <td><input size="8" onkeyup="calc(1)"value=""></td>
