Question

我有一个数组：

var array = [
    {id: "X", numberA: 1, numberB: 2, dif: 1},
    {id: "Y", numberA: 2, numberB: 3, dif: 1},
    {id: "Z", numberA: 3, numberB: 5, dif: 2},
]

我还有一个表格：

<form id="agenda_form">
    <p>ID</p>
    <input type="text" id="id">
    <p>Start<p>
    <input type="number" id="numberA">
    <p>End</p>
    <input type="number" id="numberB">
    <input type="submit" value="Submit" id="submitForm">
</form>

我正在尝试使用该表单创建一个对象并将该对象推送到我的数组中。我可以通过从数字A中减去numberB来计算。

我尝试过使用jQuery和.val（）但似乎无法弄明白。我该怎么做？

谢谢！

Answer 1

这样的事情怎么样？

var array = [
    {id: "X", numberA: 1, numberB: 2, dif: 1},
    {id: "Y", numberA: 2, numberB: 3, dif: 1},
    {id: "Z", numberA: 3, numberB: 5, dif: 2},
]

$("#agenda_form").on("submit", function(e) {
  
  var numA = $("#numberA").val(),
      numB = $("#numberB").val();
  
  var obj = {
    id: "", //whatever you need,
    numberA: numA,
    numberB: numB,
    dif: numB - numA
  };
  
  array.push(obj);
  
  //Prevent page from submitting
  return false;
  
});

试试这个。把它放到你的页面里。

HTML CODE

<form id="agenda_form">
<p>ID</p>
<input type="text" id="id">
<p>Start<p>
<input type="number" id="numberA">
<p>End</p>
<input type="number" id="numberB">
<input type="button" value="Submit" id="submitForm">
</form>

JS CODE

$(document).ready(function() {
var array = [
{id: "X", numberA: 1, numberB: 2, dif: 1},
{id: "Y", numberA: 2, numberB: 3, dif: 1},
{id: "Z", numberA: 3, numberB: 5, dif: 2},
];

$('#submitForm').on('click', function(){
  var id = $('#id'),
  numberA = $('#numberA'),
  numberB = $('#numberB');

 var k =  {id:'', numberA: '', numberB: '', dif: ''};
  k.id = id.val();
  k.numberA = numberA.val();
  k.numberB = numberB.val();
  k.dif = parseInt(k.numberB) - parseInt(k.numberA);
  array.push(k);

 });
});
